Just tested Spec Ops the Line, and it ran great, maxed out, 60 fps all round with vsync enabled. But there's no AA, so I tried to force it using RadeonPro. Still no AA, but now the Vsync has gone all wonky, keeps dropping my frames to 30. I disabled RadeonPro thinking there was some compatibility issue, but still drops to 30 all the time. Fiddled with vsync from drivers, radeonpro, in game, restarted windows, but vsync still messed up. Had to do a system restore to before when the game was installed, reinstalled, did not mess with anything, and now game runs fine again, perfect 60 fps with in-game vsync enabled. What was the cause to making vsync unstable and how to undo it if I try to mess around with settings again (i still want to try and get AA to work) without having to resort to a system restore? P.S: I know about triple buffering, it is enabled by default from radeonpro as a global setting, and it works fine, it's just when I start messing around with settings that things get weird.
