Umm, where did these people go to school?? They haven't got a single number right....
When gaming at 2560x1600 in Crysis 3 the GTX Titan X rendered an impressive 51fps on average, 46% faster than the GTX 980 and 39% faster than the R9 290X, while it was just 19% slower than the R9 295X2.
Jumping to 4K reduced the average frame rate to just 26fps, though if we were to disable anti-aliasing we would likely receive playable performance. Even so, with 26fps the GTX Titan X was 48% faster than the GTX 980 and 24% faster than the R9 290X while also being 24% slower than the R9 295X2.
That's ~%15 @ 25x16 and ~%15 @ 4K. Same misinformation through the entire review. lol
