I run my previous glut project on WinXP. But my projects are not accelerated by my Vodoo3. This not happend on Win98.
Then I try running several games and they are accelerated. What I mean is the game can detect my gfx card.
What I think is glutGameMode automatically detect my gfx card and use it. And I've see somewhere something call LCD (if I'm not mistaken). What is LCD? Is it related to my problem? Are the games that I play not using LCD? Are all opengl program use LCD?
