Test System

The test system we use is the same as we always use. A trusty Skylake running at stock speeds to better simulate the a more usual setup. PresentMON will be our tool of choice going forward due to how extensible it really is. It’s fairly easy to use and works for all titles, and doesn’t need anything specific to be able to report FPS numbers for DX12 or Vulkan games, something that is problematic for GUI-based tools.

The settings you have control over are actually quite varied, and much more than one might expect for what was primarily an Xbox One developed game.

You have full control over the texture quality, geometry complexity, shadows and of course motion blur. Reflections, shadows and mirror quality have the largest impact on FPS, though we didn’t change individual settings for the primary tests. Shadows always seem to take quite a bit of VRAM as shadow maps can be enormous. Reflections simply take a bit of computing power, though we’re under the impression that those in particular are making use of asynchronous compute.
