I am running Windows 2000 with an Asus V7700 32mb GeForce2 GTS card. Homeworld Cataclysm apparently cannot detect OpenGL compliancy despite the fact that I am running the 6.50 Detonator3 official Win2k drivers off the nVidia site. The game simply lists Software and Direct3d as the ONLY rendering systems available. The game does support OpenGL, and Quake3, which is an OpenGL game, runs beautifully. I have SP1 and all relevant Windows 2000 updates/patches from the Microsoft site. I also tried the WHQL-certified 6.62 Detonator3 drivers for Win2k, but they made no difference. If anyone has any ideas, please, advise.
