Ray, Lately I've been noticing that in certain games ATT can't force vsync on. Right now I've noticed it in Battlefield Bad Company 2, and Metro 2033. If I use the D3DOverrider portion of Rivatuner, it can force vsync on, so I know it's not the games themselves being "unforceable". Both of those games are running in DX11 mode on my 5870, so that might be the issue there. Are you aware of this issue, and if so, have any fixes or plan to fix it in a new version at some point?
