Even more fixes are landing in Preview for Steam Deck in the SteamOS 3.5.9 Preview: Well Paced Edition update. I'm enjoying Valve giving them fun code-names too.
Here's what's changed:
Graphics and Performance
- Reduced stutters when the upscale filter was set to FSR or NIS under high GPU load.
- Fixed an issue regarding frame-pacing and stutter, especially affecting some external displays.
- Fixed display sometimes getting stuck at 60Hz after returning from sleep on the Steam UI.
- Fixed an issue where a core could be stuck at 100% CPU if a game's window closed in an unclean way.
This comes shortly after the bigger SteamOS 3.5.8 Preview: Flatlined update a few days ago, as Valve continue cleaning up issues from the rather massive SteamOS 3.5 update that changed a ridiculous amount of the system.
Since it's in Preview you need to opt into it before Valve roll it out to everyone. You can opt into this in Settings > System > System Update Channel.
Are there any particular bugs you really want to see solved right now that haven't been fixed in these two recent Preview updates?
