OpenGL & DirextX

is it possible to have both directx and opengl installed at teh same time? i wouldnt have thought so, but is there any tricks to get such a thing working?

i need OpenGL for Valve Hammer Editor, but i need DirectX for most games.

im just assuming that really, what kind of support does OpenGL have for games? i mean, if i had OpenGL installed, would i have to pick games based round the fact that i am using it? i dont liek to limit my choices is all.


Yes, OpenGL libraries are shipped with graphics drivers, and DX is installed as separate package. AFAIK there is no interference between them (unless You are running both GL and DX apps at the same time - but it should only hit the performance due to context switches).
