Hm... those numbers are pretty disappointing, seeing as Civ Beyond Earth is a native port by a trusted Linux developer (Aspyr), and it has roughly halved performance versus Windows (at least on a Titan X): http://www.anandtech.com/show/9059/t...tan-x-review/8.
I'm assuming that if you were running this on a stock Ubuntu system then unredirecting fullscreen windows in compiz was enabled (even though it tends to be broken for nVidia currently and causes tearing: https://bugs.launchpad.net/ubuntu/+s...z/+bug/1307144), so I'm not sure what other performance bottlenecks there might be. I expect some amount of performance penalty just given most devs' increased familiarity with DirectX and ability to write more efficient code, but this is a little worse than I expected. I'm going to think twice about getting a larger-than-1080p monitor anytime soon -- though I doubt even Wayland and Vulkan are going to be a silver bullet here.
