The best DPI for FPS games is the one that lets you use a comfortable in-game sensitivity. Most pros use 400 or 800 DPI.
Why Not Higher DPI?
Higher DPI isn’t worse, but it means smaller in-game sensitivity values which can reduce precision in some games’ sensitivity sliders.
The Real Answer
Pick 400 or 800 DPI, then adjust in-game sensitivity until your eDPI feels right. Use our DPI Converter when changing DPI without losing muscle memory.
