I appear to be having problems with OpenGL games in windows 7. The games I have encountered this with are Neverwinter Nights, Freespace 2 (using the freespace open update, using the FSOInstaller) and just to make sure I started World of Warcraft in opengl mode to verify the problem. When running any of the games I get the same problem which is that i get horrible flickering horizontal bars on the screen. When running World of Warcraft in default (direct x) mode the problem is non existent, so I am pretty sure it is limited to opengl games. I suspect the issue may stem from the fact that I am using Windows Vista x64 video card drivers and the included opengl drivers may be incompatible. My system specs are Windows 7 x64, Intel Core 2 duo 2.16ghz running at 2.6ghz Nvidia Geforce 7600GT with the most recent 181.2 drivers and 4gb of ram.
