throttle_status, indep_throttle_status for RX 7900 XTX (Sapphire NITRO+ RX 7900 XTX Vapor-X) available from gpu_metrics almost always shows TEMP_HOTSPOT, even when idling.
Yeah I was just double checking. It could be some nvidia/Wayland issues. The stutter I still experience is when GPU is 99% used and I click and hold middle mouse button. It's very specific.
