AMDGPU-PRO vs. NVIDIA On Linux With OpenGL & Vulkan

First up is Dota 2 at a range of resolutions, beginning with 1280 x 1024 for a more CPU-limited scenario.

With Dota 2 rendering using OpenGL at 1280 x 1024, the NVIDIA binary driver performance was 10~14% higher than the AMDGPU-PRO results. Given the low resolution, there wasn't much scaling between the GPUs on either side.

When switching over to Vulkan at 1280 x 1024, NVIDIA was still leading but the overall performance was higher on both drivers. AMDGPU-PRO performance went up to 102~110 FPS compared to 87~93 FPS when using OpenGL. With the NVIDIA Linux driver, the performance went from 103~106 FPS to 120~122 FPS.

When running at 1080p, NVIDIA still was performing better than the Radeon cards on AMDGPU-PRO by a measurable difference.

But with Vulkan for Dota 2 at 1080p the gap narrowed between AMDGPU-PRO and NVIDIA. The performance overall was up for all tested hardware.
