I have G700 wired/wireless mouse for over a year and it has been working good. However, in the last few weeks I noticed that the mouse would have a "dead zone" while playing in FPS. It would literally not respond for a few seconds while moving it slowly. This happnes both in BF3 and Crysis 3. This was happening while in the "wireless" mode. I played around with DPI, but the same issue would happen at 1100 or 1500. The polling rate was set at 500, and "Use OS native drivers for pointer speed/acceleration" was checked off. Did that happen to anyone else? Any ideas to fix it?
