GLQuake / GLQuakeWorld / GLProQuake / and other GL randered Quake 1's.

well even under WinXPpro's compatibility it runs but i get a unresponive console and i can hear the demo in the background (tried resolutions 512x384x16 & 640x480x16). i can exit the game still this way also (hitting escape, then up once, <enter>, y (for yes))
but under normal running in WinQuake it runs fine, but also DOSQuake doesnt even run at all (like im gonna miss it ;))

If no opengl drivers are installed XP emulated Opengl by redirect Opengl calls from Opengl programs to an Opengl to D3D shim. This shim emulates a couple of opengl functions (most just for quake).

Make sure your video card drivers opengl ICD is installed and try again!.
