Is a fixed mouse DPI really better than changing it per game?
I’ve been trying to settle on a mouse setup for FPS games and I’m getting conflicting advice.
Some players say to lock one DPI (usually 400 to 800) and only change the in-game sensitivity per game. Others say DPI doesn’t matter much as long as the final sensitivity feels right, and that higher DPI like 1600 is fine on modern sensors.
I have three questions:
Does a fixed DPI actually help with muscle memory, or is eDPI (DPI x in-game sensitivity) all that matters?
Is there a real accuracy difference between 800 and 1600 DPI on a modern sensor, or is it mostly placebo?
When you switch games, do you match cm/360 or just adjust until it feels right?
What do you run, and how did you settle on it?

Fixed DPI vs eDPI. The physical distance per turn is what your hand learns, and that comes from DPI × in-game sensitivity (plus the game’s own scaling). A fixed DPI helps because you only change one variable, the in-game sensitivity, so your cm/360 is easy to track and repeat. Two different DPI/sensitivity pairs with the same cm/360 will feel the same.
800 vs 1600 on a modern sensor. Any decent current sensor tracks accurately at both, so the difference is small. Very low DPI with a high in-game sensitivity can feel slightly steppy, because each count gets multiplied. That’s why 800 is a common middle ground, and why going far past 1600 rarely brings a real benefit. I wouldn’t call it pure placebo, but it won’t change your results much either.
Switching games. Match cm/360 first. Each game scales sensitivity differently, so the same number feels different between titles, and converters use each game’s own constants for this. Then fine-tune by feel for a few days.
I run a fixed DPI and only change in-game sensitivity per game. I made a small tool for checking DPI that I used while testing this, in case it’s useful: mousedpianalyzers.com
