Latency
Our visualization focuses on Average Latency, presented as vertical bars to make comparing performance across different connection modes (Wired, Bluetooth, Dongle) instant and intuitive.
The chart differentiates between:
- Button Latency: How quickly the game registers a physical button press.
- Stick Latency: The delay in registering joystick movement (tested at 99% deflection).
Visualizing Stability (Jitter)
You may notice that the top portion of some bars is semi-transparent or "faded". This represents Jitter (instability):
- Solid Bar: Represents the stable, consistent average latency.
- Faded Top: Indicates the variance. A larger transparent area means higher jitter, implying the controller's response time fluctuates. A solid bar with little to no fading indicates a highly stable connection.
Deep Dive: Click the arrow to reveal Probability Distribution Charts. These show the exact breakdown of every input tested, displaying Probability (%) on the Y-axis and Latency (ms) on the X-axis.
Polling Rate vs. Latency
It is crucial to understand that Polling Rate and Latency are measured using two entirely different methodologies on our site:
- Latency (ms) is measured by the Prometheus 82 hardware. It captures the physical movement of the stick or button via hardware interrupts with microsecond precision. This is the "real-world" delay.
- Polling Rate (Hz) is measured via a Software Tool. It shows how often the OS receives reports from the USB stack.
Common Myth: A higher polling rate (like 8000 Hz) does not automatically guarantee lower latency if the controller's internal processing is slow. Conversely, a high polling rate on a chart might show fluctuations (e.g., 7800Hz instead of 8000Hz) due to OS jitter or CPU scheduling, which does not necessarily impact the hardware latency measured by the P82.
To test your own gamepad's polling rate, you can use our tool: Download Polling Rate Tester.
Testing Methods
Gamepadla ensures data integrity by combining three distinct testing methodologies:
-
Prometheus 82 (P82): Our gold standard. A custom-built hardware device that physically actuates buttons and sticks. It uses high-speed hardware interrupts to capture events, making it independent of the controller's polling rate. It provides an error margin of only ±1ms for buttons and sticks. View on GitHub.
-
GPDL Tester: An electrical monitoring tool for highly accurate button latency. While P82 simulates human-like mechanical movement, GPDL focuses on the electrical signal speed. View on GitHub.
-
Software Polling Test: A pure software diagnostic to check communication frequency. We use this to verify if a controller actually reaches its advertised specs (e.g., 1000Hz or 8000Hz) at the OS level. Download Software.
Note: By comparing hardware-level latency (P82) with software-level reports (Polling Test), we can identify if a controller has "fake" high polling rates or poorly optimized firmware.

Inner Dead Zone
The Inner Dead Zone is the area around the center of the stick where small movements are not registered. This helps prevent stick drift or accidental inputs, but if the dead zone is too large, it can make aiming less precise, especially in games requiring fine control. We evaluate the Inner Dead Zone based on how much you need to move the stick before it responds—the less movement required, the better.
The 8Bitdo Ultimate Bluetooth Controller has no Inner Dead Zone. The stick responds immediately to even the slightest movement, which is excellent for aiming accuracy and micro-control. This makes it a great choice for precision-heavy games like first-person shooters (e.g., Valorant or Apex Legends).
For comparison, many budget gamepads often have a moderate to large Inner Dead Zone, while premium controllers typically aim for a slight or no dead zone for better precision.
Want to learn more? Check out our video explanation of how the Inner Dead Zone works.
Outer Dead Zone
The Outer Dead Zone is the area near the edge of the stick’s range where further movement isn’t registered. This can make the stick feel less responsive at full tilt, affecting actions like quick turns or maximum speed in games. We evaluate the Outer Dead Zone based on how much 'lost' range there is—the smaller the dead zone, the better, as it allows full use of the stick’s range for more precise control.
The 8Bitdo Ultimate Bluetooth Controller has a slight Outer Dead Zone (0.6 mm). There’s a small portion of the stick’s range that isn’t registered, but it’s minimal and unlikely to affect gameplay noticeably.
Per-stick breakdown for the 8Bitdo Ultimate Bluetooth Controller: the left stick measures 0.6 mm, which corresponds to a slight outer dead zone, while the right stick measures 0.6 mm, which corresponds to a slight outer dead zone. This helps show whether the controller loses range evenly on both sticks or if one stick is noticeably weaker near full tilt.
Both sticks show the same measured Outer Dead Zone, which suggests consistent edge behavior between movement and camera inputs.
For comparison, budget gamepads often have moderate to large Outer Dead Zones, while premium controllers strive for minimal or no dead zone to maximize control.
Want to learn more? Check out our video explanation of how the Outer Dead Zone works.
Stick Asymmetry
Stick Asymmetry measures the consistency of the joystick's response across different directions. Ideally, if you physically deflect the stick by 80% from the center, the software should report an 80% deflection regardless of the direction. A high asymmetry score indicates a problem where for the same physical movement, the reported coordinates are inconsistent—for example, 60% in one direction and 90% in another. This creates an uneven, often 'egg-shaped,' response zone, which negatively impacts aiming and control predictability.
For the 8Bitdo Ultimate Bluetooth Controller, the Stick Asymmetry is 6.9% for the left stick and 11.0% for the right stick. Higher values can lead to noticeable inconsistencies, potentially impacting aiming or movement in games.
Testing Methodology: It's crucial to note that this test is performed at partial stick deflection (~80%), using special physical limiters (clips). Testing at 100% deflection often hides asymmetries because the controller's output is clamped at the maximum value, artificially 'smoothing' the resulting shape. Our method reveals the true performance of the stick in the ranges most critical for gameplay. This precise approach was also utilized by Linus Tech Tips in their controller review.
For comparison, many budget gamepads show asymmetry levels above 30%, while high-end controllers typically stay below 10% for better uniformity.
Learn more about how different gamepads perform in the Stick Asymmetry test and how to conduct such a test in this article. You can learn how to test joystick asymmetry yourself from this video.
Circle Error
Circle Error evaluates how closely the stick’s movement follows a perfect circle. A high Circle Error means the path is more square-like, which can cause inconsistent speeds when moving diagonally—your character might move faster or slower than expected. The lower the percentage, the better, as it ensures smooth, uniform movement in all directions.
For the 8Bitdo Ultimate Bluetooth Controller, the Circle Error is 7.3% for the left stick and 6.7% for the right stick. This is a good result, providing smooth diagonal movement similar to premium controllers.
For comparison, budget gamepads often have Circle Errors above 12%, resulting in 'square' feeling sticks, while high-quality ones aim for under 8% for better smoothness.
Want to learn more? Check out our video explanation of how Circle Error impacts performance.
Stick Bitness
Stick Bitness measures the precision of the joystick’s analog input, similar to bit depth in audio. Higher bitness means more distinct positions the stick can register, leading to smoother and more accurate control. Lower bitness can result in 'stepping' or less fluid movement, especially noticeable in slow, precise actions like aiming.
Unlike declared digital resolution, our True Bitness metric is derived from actual physical stick movement, reflecting the usable positions the stick can produce in practice. For the 8Bitdo Ultimate Bluetooth Controller, the movement-based True Bitness is 6.0 bits on both sticks. Lower bitness may cause noticeable stepping in precision-focused titles.
This corresponds to a measured Step Resolution of 0.03125 on both sticks, with about 32 SFC (Steps From Center) on each side, meaning roughly 32 distinct positions from the center to one edge.
For comparison, many budget gamepads have around 8 bits, while premium ones often exceed 10 bits for superior accuracy.
Want to learn more? Check out our video explanation of how Stick Bitness affects control. It is important to note that the video specifies the resolution of the stick, not the bit depth; the higher the bit depth, the higher the resolution.
Stick Centering
Stick Centering measures how accurately the joystick returns to its neutral (center) position after you release it. A good Stick Centering value prevents stick drift—a common issue where your character or camera moves slightly in a game, even when you're not touching the stick. The lower the percentage, the better the centering, and the less likely you are to experience drift.
For the 8Bitdo Ultimate Bluetooth Controller, the Stick Centering is 4.2% for the left joystick and 3.9% for the right stick. Values above 2% may lead to noticeable drift in some scenarios, which can affect precision in games.
This test methodology intentionally employs a more rigorous approach by implementing small-angle deflection and release, which produces the most challenging conditions for stick re-centering. This technique differs from the conventional maximum-deflection method where the stick is pulled to its full range and released, as small-angle deflection better simulates the micro-adjustments typically executed during actual gameplay scenarios, providing more representative data on potential stick drift occurrence during normal use.
Want to learn more? Check out our video explanation of how Stick Centering works.
Axis Magnet
Axis Magnet is a form of stick processing where movement tends to 'snap' or cling to the X or Y axis when the stick passes close to it within a certain part of its travel. This can make pure horizontal or vertical movement feel cleaner, but it also alters the real stick path and can distort diagonal or subtle player input.
The 8Bitdo Ultimate Bluetooth Controller shows no Axis Magnet. That means the stick does not artificially cling to the horizontal or vertical axes, so your real movement path is preserved more accurately. This is the preferable behavior for consistent aiming and natural analog control.
Want to learn more? Check out our video explanation of how Axis Magnet affects stick behavior.
Polling Rate
Polling Rate describes how often the controller sends stick data to the system, measured in Hertz (Hz). Higher values mean the controller reports its position more frequently, which can reduce the time between updates and make input feel more responsive.
The 8Bitdo Ultimate Bluetooth Controller does not have a saved polling-rate value for this test entry, so the field is shown as N/A. This usually means the measurement was not captured together with the stick data, not necessarily that the controller performs poorly.
Polling Rate is measured separately from latency, so it is best used as supporting information rather than a standalone quality verdict. In addition, this reading is approximate: Stick Tracer is not a specialized tool for precise polling-rate measurement, so some margin of error is expected.
Center Skip
Center Skip, also known as Stick Skipping, is a rare behavior where the joystick does not begin moving smoothly from its neutral position. Instead of a gradual response, it suddenly jumps to a noticeable deflection as soon as movement starts, which makes fine control much harder.
The 8Bitdo Ultimate Bluetooth Controller shows no Center Skip. That means the stick begins moving gradually from neutral, which is the expected and desirable behavior for precise aiming, camera control, and micro-adjustments.

The lower the percentage, the better the centering, and the less likely you are to experience drift.
For the 8Bitdo Ultimate Bluetooth Controller, the Stick Centering is 0% for the left joystick and 0% for the right stick. These are excellent results, as most high-quality gamepads typically have values below 2%. This means the 8Bitdo Ultimate Bluetooth Controller is unlikely to have any drift, making it a great choice for games requiring precise control, like shooters or racing titles.
This test methodology intentionally employs a more rigorous approach by implementing small-angle deflection and release, which produces the most challenging conditions for stick re-centering. This technique differs from the conventional maximum-deflection method where the stick is pulled to its full range and released, as small-angle deflection better simulates the micro-adjustments typically executed during actual gameplay scenarios, providing more representative data on potential stick drift occurrence during normal use.
Warning: The Stick Centering appears to be ideal (extremely low values, close to 0%), but this may be misleading due to the presence of an Inner Dead Zone (rated as 'med'). The Inner Dead Zone prevents small movements from being registered, which can mask potential drift and make the centering seem better than it actually is. This could affect micro-control in precision-heavy games, such as competitive shooters.

The 8Bitdo Ultimate is a solid controller, but what's up with the battery life? It feels like it drains way too fast for a universal gamepad. Anyone else noticing this issue?
I'm still not sold on the paddle layout, but I guess it's a small price to pay for the overall improvement in design. Maybe they'll get it right next time with a tiny blue controller like I suggested.
dude, you think a tiny blue controller's gonna magically fix the paddle layout? I'd like to see some actual improvements in design before I shell out cash for an overhyped redesign.
@Logan White dude, you think the paddle layout is the only thing wrong with the old controller? it's not like they're asking you to get rid of it, just an option to swap it out if you want.
I do it with a Wii U pro controller, so it's definitely doable.
I'm not surprised, those controllers are still great. You think the 8Bitdo Ultimate's latency is bad, try using a Wii U Pro with some wireless adapters, now that's lag.
oh great, the Wii U pro controller, yeah that's a great example of a non-ergonomic piece of junk that still somehow works. try using the 8bitdo for a while, see if it gives you wrist pain.
@Harrison Reed I’ve found the 8Bitdo Ultimate to be one of the best controllers I've used, and I haven't experienced any wrist pain while using it.
You'll still need some finesse to turn it off properly, that power button is tiny after all.
You're right, that power button is tiny, it can take some getting used to, but it's still way more convenient than a wired controller. Lol, guess we all learn to adapt imo.
Dude, a boomerang controller would be awesome but it'd probably get lost in the couch cushions, anyway. This 8Bitdo thing's not perfect but it's way more convenient than fumbling with a wired controller.
dude, you laughed so hard you pooted, nice, but seriously, what's with the tiny power button? how hard is it to, like, find a decent-sized one these days?
It seems the LCD model still can't be woken by the controller, despite the option supposedly existing for months. I'm not sure if it's a bug or a limitation, but it's definitely not working as intended for me.
Dude, I'm on the main branch and I can wake the LCD with my controller, check your updates, and then go into the controller settings on your Steam Deck, there's an option to wake the device via the controller.
@Andriy97 Nope, that's not accurate. The feature isn't functioning properly in the main branch yet. Also, what's the price on this controller? Is it worth it for these issues?
I understand your frustration! It's disappointing when features don't function as expected. Hopefully, they'll address this issue soon, as it's definitely a letdown when the controller can't wake the LCD.
@Andriy97 I’ve had that option enabled for a while, but pressing the PS button on my DualSense doesn’t wake my Steam Deck. It just doesn’t work on the stable version.
Sounds like a bug to me. I've had the same issue with waking it up. Definitely not working right if it’s supposed to.
Is it just me, or does the 8Bitdo Ultimate still have some serious connection issues? I’ve noticed it doesn’t always sync smoothly, which can really kill the vibe during a game. It's a shame because it feels like it could be great.
The Bluetooth connection drops too easily, which is a real hassle. It’s frustrating when I want to pick up and play but have to constantly reconnect. If they fix that, this could be a solid controller.
This controller's got potential, but it still needs work. It's annoying when it doesn't connect right away, especially for a universal gamepad.
I completely understand! It’s definitely frustrating when it doesn’t connect immediately, especially for a universal gamepad. They really need to work on that aspect.
Does the 8Bitdo Ultimate Bluetooth Controller have the ability to wake devices from sleep like my Xbox Series X controller does with my OLED screen?
It's still not perfect, but the Ultimate Bluetooth Controller is the best universal gamepad 8bitDo has made so far. I can wake it from sleep, but only in preview mode, which isn't exactly what I want.
I don't think so, the Bluetooth turns off when you put the console to sleep, at least that's my experience with the Ultimate Bluetooth Controller.
I was skeptical about the LCD support, thought it was a hardware limitation, but if they've managed to make it work, that's a big plus for me.
I've got one of these Ultimate gamepads and it's connected to my setup, works great for me.
I had a weird issue yesterday where my 8Bitdo Ultimate Bluetooth Controller connected to my PS4 controller by accident. It still worked fine after unplugging it from the dock, so I'm not sure if that's a normal quirk or not.
It sounds like a quirk of the controller. The 8Bitdo Ultimate can connect to multiple devices, but if you're experiencing issues, it might be worth checking the settings or ensuring no other devices are interfering.
I've had it turn on in my bag and start heating up, which is pretty wild, especially when it's just sitting there in its case.
I'm having trouble with the Bluetooth connection dropping on my Xbox deck, which is a major letdown since I wanted this to seamlessly replace my Xbox one for both deck and PC use. Does anyone else experience this issue?
My Ultimate Bluetooth Controller's wireless connection works fine, but I'm still not entirely sold on this one - it's the best 8bitDo controller I've used so far, but it's not without its flaws.
I tried the beta update and it's still not working, but I guess that's what beta updates are for, right?
I'm glad I discovered that the 8bitdo ultimate turns on when the case is opened, or it could've been a real disaster, especially if I'd been in the middle of a session.
Still having issues waking my Steam Deck on the stable version, but it does work on the beta version. My controller's on the latest firmware, and so is my Logitech Bluetooth keyboard, which also has the same issue.
I've got the 8Bitdo Ultimate and it's a solid controller, but I do think they could've done something to make the paddle layout more comfortable for larger hands, especially considering the overall design is otherwise pretty great.
Works with my PS5 DualSense, that's a plus. Still not perfect, but it's the best universal gamepad from 8BitDo so far.
I've had issues with it connecting to my TV's docked mode, often needing to reset the controller and reconnect. Wireless mouse trick works for me, though - just click it once to wake it up and connect the controller.
I've got the Ultimate Bluetooth Controller as my go-to docked controller and it flat out doesn't work, which is a major letdown given its otherwise solid build and decent hall effect sticks.
Still not sold on the "Ultimate" title if it doesn't bring any significant improvements over previous models. The Steam update's BLE compatibility issues are a major concern, making me question its overall usability.
dude, yeah, it's not just the 8bitdo, lots of BT controllers use BLE, it's not like they're all magically exempt from Steam's update issues, you know?
I'm still waiting for a feature that wakes my LCD Switch from sleep, which the 8Bitdo Pro 2 and Joy Cons can do. Anyone know if the Ultimate Bluetooth Controller has this capability?
Fingers crossed the purple model gets updated soon to match the quality of the Ultimate.
Just a heads up, they've added support for the Ultimate 2C in the latest firmware, so fingers crossed it'll work smoothly for you.
Does anyone know the layout difference between the black and white versions of this controller? I picked up both thinking they'd have the same layout but they don't.
Picked up this controller, but the size wasn't ideal for my hands - it took a while to get accustomed, and in the end, I opted for a different one.
Interesting to see this thing paired with a Dualsense on Steam Deck, it's definitely a testament to its versatility.
switched to 2.4gz usb instead of bluetooth for oled user and it works great, no issues here
I'm not sure if I'm just seeing improvements, but this 8Bitdo Ultimate feels like their best universal gamepad yet, still leaving room for refinement.
I'm glad to report that the latest 8BitDo Ultimate 2C firmware has resolved the issue with waking my Steam Deck from sleep, although it wasn't working on the previous stable version.
