Well I thought my crappy audigy2 zs platinum pro sound card drivers were holding me back but after updating those correctly thanks to daniel_k cd and creative updates I still have that sync loss problem with both supreme commander and scFA for movie playback and briefing videos, rest of the game is just fine though. Maybe these games don't correctly support 1680x1050? I say that because I used to have a 19 inch samsung 2ms lcd monitor that ran at 1280x1024 and it worked just fine with scfa as long as the vsync was on. I turn it on off it doesn't matter now lol.
