i know with directX you can check the system to see what the video card can do. how do you accomplish the same task with opengl? is it even possible?

as many makers of commerical apps will tell u, u cant rely on capsbits in directx, very often they give incorrect data.
basically the safest method is to do a little test, see if it worked. if so the card + drivers can do it, if not then look for alternatives. use the same method also if u want to find out if a particlur feature is quick enuf

In OpenGL, you can just query the version of the ICD (if its 1.3, then it *should* support all the 1.3 calls), and you can query the extensions string.
