#Edit: This has been resolved now.
For those of you who've been using the Steam Deck variant of Bazzite on desktops/HTPCs with AMD GPUs - beware that currently there's a bug affecting (some?) users, where the GPU's TDP is capped to just 15W!
You can check your settings by running a tool like LACT (ujust install-lact):
As you can see, LACT shows the current limit is 15W, but it can actually go upto 280W on my card.
A bug report for this was opened last year, but it was closed as fixed, but at least one other user (besides me) has been experiencing it - so check your wattage, you might be affected too!
At the moment there are no actual fixes - but you can try the workaround posted in the original bug report. Also, using tools like LACT or corectrl isn't a fix unfortunately, because as soon as you go into game mode (or reboot), the limit resets back to 15W. I'm currently troubleshooting this with a couple of the developers, and hopefully we may get to bottom of this soon.
As for the performance impact - here's a screenshot of Last Epoch running at a glorious 4 FPS, thanks to the caps:
Thanks for confirming that. Yeah there was another report saying that the desktop image was fine. Seems like there's something extra in the Deck image that's enforcing this limit.
