I ran it again and again and a g a i n. Sorry, it's trippy. When I got back to the real world I could see steady 12 FPS...
I think it's a better test than Furmark, more enjoyable. In 64bit exe which runs by default Afterburner can't display so make sure you run the32bit which you find in your install folder. In top left there's an arrow where you can set, well, the settings. It runs Ultra by default hence the 12FPS.
It is really made for 690 or 680/70 SLI but nevertheless it is beautiful and runs smooth at the aforementioned 12-14 FPS on my card. Have fun.
