G-series Gaming Mice

[hekturr]

Hi I've had my Logitech G400 Mouse for about 4 months now. I've noticed that during a majority (almost all) of the PC games I play if I move the mouse too fast it will cause a huge drop in FPS. I've tried it with V-Sync on and off, and i still does it. It even cause audio lag if I move my mouse in a circle or too fast from one corner of the screen to another which is horrible for playing MOBA style games. I've tried looking for fixes but I haven't found anything. Also I tried downloading the Logitech Gaming SOoftware to try and update my drivers but the program never opens. I tried running it as admin, but it never opens.I have WIdows 7 64bit. If anyone has any help on this I'd love to hear, I'm close to switch back toa generic mouse that doesn't cause constant fps drops.
