cadaveca, what you tell is simply impossible.

you can't bring 200fps to stuttering in cf/sli.

If you have 200fps with CF, even in the WORST situation, means when both cards pump out 1 image each at the exacly same time, it would feel like 100fps.

But that's not possible, as the cpu can't "prepare" for 2 images at the same time.

So even if your cpu is capable of 1000fps, it would mean there is at least 1ms between the frames, making 200fps@CF feel at least like 111fps.

If you feel that, you must be god.
