In the Ashes of the Singularity game we set the graphics quality to the highest "Crazy" setting and run the test under full HD and 4K for both DirectX11 and DirectX 12 APIs.

The advantage of GeForce GTX 1080 Ti in the Full HD test is about 6% for DirectX 11 and about 21% for DirectX 12. The result can be explained considering that the CPU bottleneck factor becomes lighter under DirectX 12.

In the demanding 4K test, as the frame rate drop, the CPU becomes a bottleneck less, and the average frame rate of DirectX 12 and DirectX 11 is not as much as the full HD

In the Overwatch FPS game we set the video quality to the highest "Epic" settings and again we measudered the average FPS for each card under different resolutions.

Here the GeForce GTX 1080 Ti has a lead of about 29% for Full HD, 32% for WQHD and 30% for 4K. The potential of GeForce GTX 1080 Ti is fully demonstrated in the low resolution tests.
