It's need to out large RGB picture to OpenGl window.
I do it with simple:
All nVidia cards (GeForce, old TNT,etc..) shows good fast result, but INTEL or some ATI cards (include top) shows up to 10(!) times more to draw such picture...
My init of OGL:
mov ecx,sizeof.PIXELFORMATDESCRIPTOR shr 2

I don't know the specific problem here, but a few hints - not all from my knowledge (some from articles I've read):
1) The Intel video hardware is not capable of meeting very high standards - that is what you need an external card for. Intel has made many efforts to support all the newest technologies like SM3.0 etc. so it doesn't suck completely, but there is a limit of how much you can stuff on this rather small chip with passive cooling.
2) There have been many tries from ATI to make its technologies, but (this is only MY opinion - not to be quoted!) it seems that they have failed because the mainstream has been moving in other directions. For ATI I would say that they have had the best quality to speed ratio, but in most tests they only test speed - that is why nVidia came on top.
3) Of course there's an issue of angry Linux people because ATI worked worse with drivers than nVidia WITHOUT! Furthermore ATI's drivers gave a 2x boost while nVidia's ones more like a 1000x boost in performance. However, there was an article not long ago that said ATI to release better drivers.
Like I said - I don't know the specific cause, but one or more of these points might bring more light.
