AMD Ryzen 5 2400G Radeon Vega Linux OpenGL/Vulkan Gaming Benchmarks
Dota 2 at 1080p with OpenGL on the latest Linux graphics drivers delivers around a 53 FPS average for the Ryzen 5 2400G. Hopefully with continued AMDGPU/RadeonSI optimizations, this could eventually rise above 60.
While using the RADV Vulkan driver with the Ryzen 5 2400G is a few frames slower.
Serious Sam 3: BFE with Vulkan is easily playable at 1080p with the Ryzen 5 2400G.
