How to compare two controllers for stick accuracy

One controller feels precise, while another seems to drift, skip or struggle to make small adjustments. A game can make those differences hard to judge because its sensitivity and deadzone settings affect what you feel.

Test both controllers in the same place before changing game settings. The Gamepad Test shows stick input in your browser, so you can compare how each one responds to the same movements.

Compare the controllers

1. Open the Gamepad Test on the computer you use for gaming. Connect the first controller. If the browser does not detect it right away, press a button on the controller to wake it.
2. Leave the sticks untouched for about 10 seconds. Watch the stick response on screen, and note whether it stays centered or moves by itself.
3. Move one stick slowly from the center toward each edge, pausing at several points. Repeat in the opposite direction, then move the stick around the edge in a circle. Avoid pushing harder on one controller than the other.
4. Repeat the same checks with the second controller. Use the same browser, computer, connection type, and test movements. If possible, reconnect the controllers one at a time so the test is clearly responding to the one you are holding.
5. Repeat any movement that looked uneven. A single jump can be a missed sample or a brief connection hiccup. Look for the same behavior on more than one pass.

For the fairest comparison, use a fully charged wireless controller or connect both controllers by cable if that is an option. Keep your hand position and movement speed similar. Do not compare one controller over Bluetooth with the other over USB unless you specifically want to compare those connection methods too.

What the result means

The stick stays near center when untouched

That is a good sign. A small, stable difference between controllers does not necessarily mean either one is defective. Sticks can report slightly different center values, and the test cannot establish how a particular game will treat those values.

The stick response moves while your hand is off it

This may be stick drift: the controller is sending movement even though the stick is at rest. Repeat the check after releasing the stick gently and letting it settle. If the movement keeps returning on one controller, compare it in a game with the same deadzone setting. A game deadzone is the small area around center where the game ignores input, so a larger deadzone can hide mild drift.

The response jumps or hesitates during a slow sweep

Repeated jumps in the same part of the movement can point to a worn stick, a connection issue, or a controller profile that changes the input. If the problem occurs only once, test again before drawing a conclusion. Also try another USB port or reconnect the wireless controller.

One controller reaches the edge sooner

The two sticks may have different calibration, travel, or output ranges. A browser test is useful for comparing movement patterns, but it does not guarantee identical readings or prove that one controller is more accurate in every game. What matters most is whether movement is smooth and repeatable, and whether the difference affects the way you play.

Both look smooth here, but one feels worse in a game

The issue may be in that game's settings rather than the controller. Games can use different sensitivity, response curves, and deadzones. A response curve changes how quickly in-game movement increases as you tilt the stick. Compare the controllers using the same settings in the game before deciding that a controller is at fault.

How to make the comparison fair

1. Use the same connection method. A low battery, wireless interference, or a loose cable can affect input. For Bluetooth, disconnect and reconnect the controller. In Windows 11, check Settings › Bluetooth & devices. On a Mac, check System Settings › Bluetooth.
2. Close remapping software. Controller tools and some games can change stick response or create virtual controller inputs. Close them while testing, then reopen them one at a time if you need to find which profile changes the result.
3. Check for a game-specific deadzone. If drift appears in the browser but not in a game, the game may be filtering small inputs. If the controller seems unresponsive near center in the game, its deadzone may be set too high. Change only one setting at a time and repeat the same movement.
4. Compare each controller in the same game. Use the same character, camera view, sensitivity, and deadzone. Make small left and right movements, then repeat them with the other controller. This checks what you feel during play, not just what the browser receives.
5. Restart and test again. Disconnect the controllers, close extra games and controller utilities, then reopen the browser test. This can clear a stale connection or an app that is intercepting input.

When the controller may be faulty

A controller is more likely to have a hardware problem if the same stick repeatedly drifts, sticks, or jumps in the browser and in more than one game, while another controller behaves normally on the same computer. Check for dirt around the stick and make sure the stick returns freely to center. Do not spray liquid cleaner into it.

If the problem continues after reconnecting and testing without remapping software, check the warranty or contact the manufacturer. For an older controller, a replacement stick module may be possible, but it can require soldering and careful disassembly. If you are not equipped for that repair, use a repair shop or replace the controller.

What a browser stick test can and cannot tell you

The test checks the controller input that reaches the browser. It can help reveal center movement and inconsistent response, but it cannot measure the force needed to move a stick, inspect its internal parts, or reproduce every game's input processing. A smooth test result is useful evidence, not a guarantee that the controller will feel identical in every game.

Compare repeatable behavior rather than expecting two different controllers to show exactly the same response.
