Yeah youre right. There is harsh FPS drops on the 660ti tri sli.
How did you found that out, if that's not a secret?
I was always under the impression adding more cards into SLI/crossfire would always give less return than the previous card added. i.e 100% for the original card, +95% for the second card, + 80% for the third card and so on...
Not really sure it does work in % rate. Drivers+game optimization. Look at metro benches.Originally Posted by chaogui

However looking at that Battlefield 3 test in particular, at 5760 x 1080 the second card only gave an extra +31% in FPS relative to a 1 card setup. However, the third card somehow managed to give a +45% boost. At such a high resolution with those AA settings, I would have expected the 660 Ti to be so heavily bottlenecked by VRAM that the third card wouldn't give much improvement at all. I have no idea how it managed to give more of a FPS boost than the second card did, could an OCN pro please explain?![]()
My bad, my graph reading skills must be extra fail today. I looked at the first few benchmarks and assumed that the last one was a 660 Ti, only see that it is a 680 after you pointed it out. Now I feel sillyOriginally Posted by DiNet

Plus they didn't provide single 660ti bench in this graph. Drivers change, game updates change fps too, so looking at older benches doesn't give precise numbers.
P.S. Your % numbers are way too high anyway![]()
