Summary
Valve released SteamOS 3.8.28 Beta with a fix for game performance drops that could hit systems using discrete AMD graphics after sleep and resume.
The changelog says the bug affected AMD discrete GPU systems, including Steam Machine hardware, though Valve did not specify which GPU generations were impacted or how severe the slowdown was.
The 3.8.28 update is available on SteamOS Beta and Preview channels through Settings > System > System Update Channel.
Valve has patched similar suspend-resume issues before, including reduced CPU performance on Steam Machine and fixes in SteamOS 3.9.1 Preview for RDNA1 and RDNA2 dedicated graphics.
