Geforce 7600GS+91.31 drivers at the time it was enabled and installed. Played a game of UT2004, hit CTRL+T to enable, thought it was cool. NHL 09 wasn't as cool, wanted to disable it, CTRL+T; all it does is a slight drop in saturation, and only if you're really watching. Went into Nvidia 3d stereo settings, changed from "Enabled by Hotkey" to "Disabled"...nothing. I also had to disable AA for 3d Stereo games for performance. Now the "Disable AA when Stereo is Enabled" Is unchecked but no AA, can't get it back on. I uninstalled all those drivers with Driver Sweeper as suggested by a 3d gaming site, now running 162.50 drivers. Any help is appreciated, and thanks in advance. Edit: Now Running 181.20 drivers.
