Frequently Asked Questions
What is Timer Resolution in Windows?
Windows Timer Resolution controls the global system clock tick interval. The default Windows timer resolution is 15.6 ms. Reducing it to 0.5 ms or 1.0 ms using timeBeginPeriod(1) improves input responsiveness in competitive gaming.
Does changing timer resolution increase FPS?
While it does not boost GPU framerates directly, setting a 1ms timer resolution lowers input lag and reduces micro-stuttering in fast-paced competitive esports titles like CS:GO, Valorant, and Fortnite.
