for some reason the vsync turns off when i enable crossfire...i run 2 x1800xl 512mb cards, which ati says that are not supported officially, but people are running xl 256mb succesfully...x1800gto is pretty much 4pipe locked xl...so somehow the drivers dont force vsync to work on both cards...anyone can help or tell me a program that i can try to force vsync with...i tried in games, in ccc nad ati tray tools and there is tearing all the time in all games
