Poor OpenGL Performance on Vega Starting w/ 17.9.3

Question asked by cybereality on Oct 13, 2017

My RX Vega 64 system was working great initially. Then after installing the 17.9.3 driver (also 17.10.1), OpenGL performance has tanked.

 

So far, I have tried RAGE and DOOM (OpenGL) and performance is less than half what it was before. For example on RAGE I was getting around 75 - 80 FPS 4K max settings, now I'm only getting around 30 FPS. DOOM is similar. WebGL is also affected. DirectX and Vulkan games are running at full speed with no problems. Please help.

 

Here are my specs (on Windows 10 64-bit).

 

AMD Ryzen 7 1800X | MSI X370 Titanium | G.Skill Flare X 16GB DDR4 | EVGA SuperNOVA 1000 | Corsair Hydro H110i

Gigabyte RX Vega 64 x 2 | Samsung 960 Evo M.2 500GB | Seagate FireCuda SSHD 2TB | Phanteks ENTHOO EVOLV
