Why these tools matter
Your aim depends on your sens. Your sens depends on your DPI. And both of those interact with the game-specific yaw constants. If you switch from Valorant to CS2 without converting, you’re effectively learning a new game — your muscle memory is calibrated for a different number of degrees per millimeter of hand movement.
The same goes for crosshairs: a custom crosshair that’s tuned for visibility against your specific game’s lighting will give you fractions-of-a-second faster target acquisition. Over hundreds of duels, that adds up.
How they connect to the rest of FastX
- Use the sens converter to set your aim before training in the aim trainer or tracking test.
- Pick your crosshair, then go test your reflexes in the reaction time test and choice reaction test.
- The Lab bundles tools and tests by skill goal — if you’re focused on aim, start there.
