I am having problems with my All-In-Wonder Radeon. In OpenGL, it's quite obvious that VSync is disabled. I get image tearing, etc. I can enable and disable it in ATi's control panel as much as I like, ...

Recently I've installed Windows 2000 on my system; my video card is an NVIDIA TNT2 Ultra (32mb). I play TFC (a Half-Life mod) on a very regular basis, and as such I attempted to start a game of it.
