It's the graphics drivers mostly - please stop blaming ID Software. Carmack already said at quakecon that GPU drivers are the most frustragin thing on the PC - because of abstraction and and brute force needed -
One of the most important things is this is OpenGL , it's not DirectX and GPU vendors just weren't prepared or how should i say -- definitely less effort on that obviously.
