Ran my controller through it and the drift test caught an issue I didn't even notice in games. Love that everything runs locally.
@fatmazaytr9gjw Thank you Fatma! 🙌 That's exactly the scenario I built it for — small drift hides in games because most titles apply a deadzone on top of the raw input, so you never see it until it gets bad. The test reads the raw values, which is why it caught it early.
Out of curiosity, what deviation % did it show? If it's in the 2–5% range, recalibrating or cleaning around the stick base usually buys you a lot of time before it needs a module swap
finally something that runs my controller drift test without forcing me through a sketchy exe. refresh rate check felt accurate against my monitor's spec, too.
@sinan108042 Thanks Sinan! The "sketchy exe" problem is literally why this exists 😄
Glad the refresh rate test matched your spec — it measures real frame timings via requestAnimationFrame instead of just reading what the OS reports, so it catches cases where a 144Hz monitor is silently running at 60Hz because of a wrong cable or display setting. If it ever shows a number lower than your monitor's spec, that's usually the cable/settings, not the test.
