More information

Latency

This chart shows how quickly your gamepad responds to button presses as well as joystick deviation. Each point on the graph represents a test result.

  • The horizontal axis (X-axis) measures the time elapsed from the button press or stick deflection to the game's response. This time is called “latency”.
  • The vertical axis (Y-axis) shows how often we got such a result, in percentages.

If you hover over a point on the graph, you'll see how long the latency was and how often it occurred.

The lower the latency, the better. In a perfect world, as soon as you press a button or move the joystick on a gamepad, the action in the game happens instantly. If there is a long delay, you can press the button, but the action will take some time. In fast-paced games where every second counts, a long delay can be a problem.

Use this chart to figure out how fast your gamepad reacts.

Polling rate

The polling rate (also known as the Refresh intervals) in gamepads refers to how often the controller sends input information to the console or computer. It's measured in Hertz (Hz), which translates to the number of times per second the device reports its status to the computer.

For example, a gamepad with a polling rate of 125 Hz sends its status to the computer 125 times per second, or every 8 milliseconds.

The polling rate is essential in gaming for two reasons:

  1. Responsiveness: A higher polling rate means the controller communicates its state to the computer more frequently, resulting in faster and more responsive gameplay. In fast-paced or competitive games, even a slight increase in responsiveness can give players an advantage.

  2. Accuracy: A higher polling rate can also increase the accuracy of the controller. This is particularly important for devices like gaming mice, where precise movements can be critical, but it can also impact gamepads, especially in games that require accurate inputs.

However, it's important to note that a higher polling rate can also put more strain on the computer's CPU, as it needs to process inputs more frequently. Moreover, beyond a certain point, increases in polling rate may not yield noticeable improvements due to limitations in human reaction time and display refresh rates.

Jitter

Jitter is a measure of how much the gamepad's latency varies during testing. It is calculated as the standard deviation of the recorded delay times. A lower jitter value indicates more consistent latency, while a higher jitter suggests unstable performance. Low jitter is important for a smooth, responsive gaming experience.

Inner Dead Zone

The inner dead zone is an important parameter for stick control. It helps avoid drift or accidental movement, but if this zone is larger than the necessary minimum, it can significantly impact aiming accuracy in games. Therefore, it is better when the inner dead zone is minimal or absent.

Gamepad Flydigi Apex 4 has no inner deadzones, which has which has a positive effect on aiming accuracy and micro control.

Outer Dead Zone

The outer dead zone indicates the extent to which there is an area where stick movement is not registered when fully deflected. If it's small, it indicates high stick calibration accuracy. In the case of a large outer dead zone, it significantly limits the useful range of motion and can have a negative impact on control.

The Flydigi Apex 4 gamepad has normal external stick dead zones (0.6mm). Its significant presence does not limit the range of motion and does not have a negative impact on control.

Stick Resolution

The stick resolution of the Flydigi Apex 4 gamepad has a motion resolution of 0.00069. This means that it can register 1449 positions from the center point of the stick to its outermost edge. This is similar to the resolution of a monitor, where more pixels provide a clearer image. In the case of gamepad sticks, higher resolution ensures smoother and more precise control. As a rule, 125 positions are more than enough for a comfortable game.

It is important to know that some gamepads do not have a constant resolution and give out 0.0078 or 0.0150 (for example). Therefore, the number of end positions may differ from the real ones.

Asymmetry Index

The Asymmetry Index measures the difference in the left-right and up-down deflection of the joystick. A higher difference indicates worse joystick movement. The largest difference in the X and Y axis deflection is selected as the index. This indicator helps to understand the joystick's performance during small, precise movements that are critical for aiming and typically use 25-60% of the joystick's range of motion.

The asymmetry index of the Flydigi Apex 4 gamepad is 3% for the left stick and 4.6% for the right stick.
Learn more about how the measurements are made.

Circle Error

The "Circle Error" parameter determines the behavior of the stick at its extreme diagonal positions. With the Joystick Tester program, you can check how accurately the gamepad stick draws a circle in its movement. The lower the error value, the better. The Flydigi Apex 4 gamepad has 9.2% left circle error, and 8.2% right circle error.

Central Accuracy

The stick centering parameter indicates how well the stick returns to the central position after the player releases it. This characteristic is responsible for stick drift: the lower the Central Accuracy value, the better. The average worst position at which the joystick stops is taken as a measurement and is not touched.

In the case of the Flydigi Apex 4, the Central Accuracy for the left joystick is 0.4%, and 0.2% for the right stick.

Disclaimer

All conclusions of the Flydigi Apex 4 gamepad are based on a single gamepad, which does not rule out the possibility that other units of this model may perform better or worse. However, this variation is usually insignificant. The test data was obtained using Joystick Tester program, and some parameters may differ in other programs.

The outer deadzones of the Flydigi Apex 4 gamepad has a noticeable size (0.8mm) that partially limits the useful travel area of the stick.

Stick Resolution

The stick resolution of the Flydigi Apex 4 gamepad has a motion resolution of 0.00071. This means that it can register 1408 positions from the center point of the stick to its outermost edge. This is similar to the resolution of a monitor, where more pixels provide a clearer image. In the case of gamepad sticks, higher resolution ensures smoother and more precise control.

Stick Movement Linearity Test

Resolution test for Flydigi Apex 4 • Firmware 6.8.3.5 • Stick Analyzer 2.0.0.0 • Dongle connection • Xinput mode. Uploaded, by John Punch

Resolution Test Results

The joint motion resolution test shows how many unique positions the controller can register during smooth motion. This test was performed using a linear motion from the center to the edge of the stick range using the Stick Analyzer program.

Total Points

Total Points represents the number of unique positions that were registered during the smooth movement of the stick from center to edge. This includes both clean analog values and positions affected by noise or jitter. In our test, we got 1443 points, which is an excellent result that indicates very precise stick movement registration. However, it's important to look at the Analog Points as well, as they show the true stick resolution without noise.

Analog Points

Analog Points shows the number of unique positions after filtering out noise and jitter. The test registered 1443 analog points. This is an excellent result, indicating very smooth and precise stick movement. This value is especially important as it represents the actual number of unique positions the stick can report reliably.

Tremor

Tremor percentage shows the difference between raw stick movement data and its processed signal. This is a technical characteristic of how the controller processes physical stick movement - higher values indicate more active signal processing, while lower values show more direct translation. The test showed 0.0% tremor. This indicates very stable stick movement with minimal noise in signal processing. It's important to note that tremor is just one of many factors in controller performance and doesn't directly correlate with aiming accuracy in games.

Step Resolution

Step Resolution shows the average size of movement steps between registered positions. Lower values mean finer control and smoother movement. The test measured 0.00069 average resolution. This indicates excellent stick precision, allowing for very fine control. This parameter directly affects how smoothly you can aim or control camera movement in games.

Test Duration

The time taken to complete the test was 7.86 seconds. This is an optimal test duration, providing reliable results. For the most accurate results, the stick movement should be smooth and controlled, typically taking between 3 and 10 seconds.
