Serious Sam 3 - BFE: OpenGL vs. Vulkan With Fusion 2017 Update
At 1080p high quality settings with OpenGL, the R9 Fury and RX 480 were slightly faster than the GTX 1060...
And switching over to Vulkan had yielded a boost in frame-rate for most of the graphics cards tested (except for the GTX 1050). But the NVIDIA Vulkan performance relative to OpenGL remains greater than RADV Vulkan.
4K with high quality settings had the GeForce GTX 1070 or R9 Fury being faster than a 60 FPS average.
The 4K high quality settings run with Vulkan showed faster NVIDIA Vulkan performance but the RADV performance was slightly lower.
