Trying to start the game results in everything OK, except:
 
Initializing OpenGL driver
...getting DC: succeeded
...GLW_ChoosePFD( 16, 16, 0 )
...35 PFDs found
...GLW_ChoosePFD failed
...failed to find an appropriate PIXELFORMAT
...restoring display settings
...WARNING: could not set the given mode (3)
...shutting down QGL
...unloading OpenGL DLL
...assuming '3dfxvgl' is a standalone driver
...initializing QGL
...calling LoadLibrary( 'C:\windows\System32\3dfxvgl.dll' ): failed
...shutting down QGL
GLW_StartOpenGL() - could not load OpenGL subsystem
 
Read the stuff on regedit but don't have an advanced features to edit/delete. D/l'd 3dfx 3-4-5 winxp test but don't know if I should run it before doing something else. Ideas, suggestions, etc. appreciated.
