Hi. I have a evga gtx 560 ti that has been running the 314.22 driver since it came out. Everything has been good with it. But recently I did a clean install of win 7 and windows update installed the latest 340.52 driver version. For some reason, After installing both that driver and the latest flash player 16.0.035, I'm getting more blur and motion issues in both my games, win media player, homecinema and youtube. Is there a problem with the latest drivers and should I go back to 314.22?
 
Issues are framerate drop in halo pc and halo custom edition, some lag in gta 4, extreme tearing and green flickering Battlefield 3, more pixelated playback using homecinema for mkv files, and more blur on youtube.
any advice would be appreciated!

I really sound dumb asking this, but when removing and re-installing drivers which should I delete and which do I keep? There is a 3d vision controller, 3d vision driver, graphics driver, hd audio driver, physX system software as well

I found a problem, when I go to the nvidia folder to delete, all I see is some older ones. 340.52 isn't there
