With a MS Sidewinder X3 at any DPI and my motherboard (ASRock H87 Fatal1ty) boosting the mouse polling rate, I notice no lag in Warframe, LoL, Dota 2, Vindictus, Battlefield 3 & 4 beta, and Rome II TW. I've been running Windows 8.1 RTM since it was released on MSDN a couple of months ago.
Now, before I boosted the mouse polling rate, I did notice some mouse lag issues, but was right after I cleaned my dusty glass desk, so I need to faster polling for a laser mouse to consistently read on a clean and clear surface. Lol.
