Tests were done on the same system as the recent Talos Principle NVIDIA comparison using that new test profile on OpenBenchmarking.org. The GPUs I tossed in for this weekend comparison were a GTX 680, GTX 750, GTX 760, GTX 780 TI, GTX 960, GTX 970, GTX 980, GTX 980 Ti, and GTX TITAN X.
At 1080p obviously not a lot different with regards to the frame-rates for this battle arena game as they are all fast and modern GPUs and this Source 2 engine game bound by the CPU at 1920 x 1080:
But things become much more interesting at 4K:
For going through all of the data including 2560 x 1440 results for Dota 2 on this NVIDIA Linux setup, visit this OpenBenchmarking.org result file.
There is also this OpenBenchmarking.org result file with some system monitoring data.
Wondering how the NVIDIA results compare to yesterday's open-source Radeon results with Mesa 11.2-dev and Linux 4.5? It's easy with some simple OpenBenchmarking.org magic. Check it out.
