Serious Sam: The Second Encounter's GLSetup says that I should get OpenGL drivers from grapic card manufactuer, but ati does not have such a thing. I've also searched using google for opengl drivers windows xp but no success. Is there any OpenGL driver installation available for download or should I reinstall windows, like I'm going to do because games like Doom3 doesn't work at all because dx is dead.
do that anyway. OpenGL drivers are included in cat releases (...) and you'll probably need a cat 6 series driver for such an old card, or maybe a modified newer driver (?) :-
For now I've solved OpenGL by installing Catalyst 7.4 (7.2 was previous installation) and dx is somewhat solved by overwriting some dx files, which I got from computer whose dx is healthy.
