Interesting Stefan, I didn't know that.
So how would one achieve similar effect on non-quadro cards?
To my knowledge:
1) Use Linux/OS X
2) Soft-mod your Geforce to a Quadro
3) It might be possible with ATI cards, I haven't checked that for
some time.
Surely it must be possible to use two GPUs independently?
You can, just not with OpenGL. Cuda, OpenCL and iirc Direct3D can
address individual GPU's.
If not, that means that multi-GPU systems are inherently broken on
windows?
Depends on you definition of broken. For a user it is certainly good
to be able to drag GL windows across GPU's.
Also the overhead is 'just' broadcasting GL commands to all GPU's. If
your window covers only one GPU, the other GPU(s) will have no
fragments to process.
Or can I setup truly independent screens in driver settings, like
with X?
Not that I am aware of, but I'ld like to know if you find a solution.
Cheers,
Stefan.
