Intel vs. Radeon vs. NVIDIA OpenGL/Vulkan Linux Driver Performance

Serious Sam Fusion 2017 with low quality settings at 1080p saw the Intel Vulkan perforance coming up short of OpenGL while RADV and NVIDIA's Vulkan performance were both much greater than OpenGL.

Vulkan allowed the Serious Sam Fusion 2017 performance at low quality settings to be almost 60% faster on both the Radeon RADV and NVIDIA drivers.

With ultra quality settings, the gains were much less for RADV and NVIDIA with the GTX 1060, but the GTX 1080 still was able to benefit greatly from Vulkan at ultra image quality settings.

With the more graphically demanding Serious Sam scenario, RADV and NVIDIA with the GTX 1060 were only around 10% faster, but the GTX 1080 saw a 30% boost in frame-rate with Vulkan.

Looking at the CPU utilization in the different scenarios across all the tests, we see the average CPU usage was somewhat similar between these different runs with OpenGL and Vulkan, but when using Vulkan, the CPU utilization peaked much less than when using OpenGL.
