After cranking the resolution up to 2560x1600, the GTX Titan was reduced to a still highly playable 59fps, while the GTX 680 got by with 46fps. Again the GTX 670 took out the HD 7970 GHz Edition, this time by 2fps, while the standard 7970 averaged just 36fps making it slightly faster than the GTX 660 Ti. Below the GTX 660 Ti, we have the 7950 Boost with just 34fps, while the standard 7950 averaged 32fps
With a frame rendering time of 25ms, the GTX Titan effectively only delivered 40fps, the GTX 680 was much slower at 40ms (25fps), and the HD 7970 GHz Edition took 49ms (20fps). While the latter two did provide playable performance, it wasn't quite as smooth as the frame per second data above might suggest.
