In the last few builds I have had no issues, but in build 199 I am now getting a substancial amount of screen flickering (horizontal bars, I assume this is due to vsync?), which has not been present before. Running on windows 7, i7cpu, all drivers are updated etc.
NS2 is the only game that is giving me this issue.
Anyone else noticed this or how to address it? I couldn't find any information in my initial searches.
