Resume after Suspend throttles GPU

  • I'm on the deck-ISO, updated on April-5th but I've seen the issue since first installing ~two weeks ago
  • Machine is a custom HTPC, GPU is an RX 7600, CPU is a 7700x
I have no issues with any hardware when running any games I've tried on normal launch and play for any amount of time, but after I sleep and then resume the GPU appears to be throttling / spiking to 100% usage and limits game performance. No real consistency in clocks or watts dropping when it does throttle (playing Zelda TOTK on yuzu watts drop to 35 when usually in the 50-60s, playing Risk of Rain 2 watts drop to 125 when usually around 140), but it says 100% usage in steam overlay and clearly is causing FPS slowdowns.

If I close the game and relaunch whatever I was playing the throttling is completely gone.

Not really sure how to troubleshoot this, but open to trying anything. Definitely curious if anyone else can replicate this. Thanks in advance.
