Retroarch doesn't find Vega M GL, only iGPU


#1

I’ve got a machine with one of the weird frankenstein Kaby Lake G 8705-G processors – it’s got both an Intel HD 630 and a Vega M GL GPU. I’ve installed the latest drivers available (including the Vega M driver from Intel). None of Retroarch’s graphics drivers recognize the Vega M GL at startup, however. Here’s the log when using Vulkan:

Here’s the same for OpenGL:

I should mention that other games (for example, games on Steam) utilize the Vega M GL so I know that it’s usable. Are there any settings I need to tweak to get Retroarch to recognize it, or is this GPU unsupported?


#2

I figured out how to force using the Vega M GL. In the “Radeon RX Vega M Settings” panel, under System > Switchable Graphics, change the “Running Applications” tab to “Installed Profiled Applications”. Click “Browse” and select the RetroArch binary – this should add an entry into the list. Click on the new entry and in the list select “High Performance” and you’re good to go! I verified that both the log shows the Vega M GL being selected and the task manager shows high utilization on that GPU (instead of the integrated Intel HD 630).
