Benchmarks: Civilization: Beyond Earth, Total War Attila, Assassin's Creed Unity
The GeForce GTX 980 Ti had no problem delivering playable performance at 2160p in the Civilization Beyond Earth late game test. With an average of 52fps the GTX 980 Ti was just 7% slower than the Titan X and 21% faster than the GTX 980. It was also 24% faster than the Radeon R9 290X.
The GeForce GTX 980 Ti ran into a CPU bottleneck at 1600p, as did the Titan X and original GTX 980. This bottleneck was removed at 2160p making the GPUs the limiting factor and as such the GTX 980 Ti was 6% slower than the Titan X, but 25% faster than the GTX 980, while it was a whopping 67% faster than the R9 290X.
Assassin's Creed Unity was tested using FXAA with PCSS (Percentage-Closer Soft Shadows) disabled and despite that the game was still very demanding at 2160p. Here the GeForce GTX 980 Ti averaged just 34fps, making it 8% slower than the Titan X, but 17% faster than the GTX 980, while it was also 26% faster than the Radeon R9 290X.
