I tried a few games, there was a performance hit on all of them for openSUSE, I tried editing power states, P1/P2 settings, nothing helped, I’m not really sure what’s going on because nothing jumped out at me, gputop looks the same between other distros and openSUSE, nvtop too, CPU usage looks fine, it’s beyond me unfortunately.
I tried disabling selinux, switching to 64 bit steam, distrobox steam, forcing the correct GPU VK ICD file, running an embedded gamescope session, enabling NTSYNC, different Proton versions, switching to XFS from BTRFS with no snapshots, longterm kernel, nothing has helped and I don’t know what more I can do unfortunately!
I can only suggest submitting a bug report with the relevant graphics details, and logs or performance results illustrating the issue, and a link to this topic for additional info.

@Shortwave8115 Is you user a member of the video and renderer groups?
I will check, good call, failing that, I’ll see if I can make a bug report, thank you!
They weren’t, but I added them and no change, I don’t think I’ve ever added a user to those groups before!
@Shortwave8115 it’s needed for the likes of Level Zero, I also pushed updates for openvino to use the npu, just did an update for intel-media-driver as well.
I haven’t push my intel raytracing package yet…
Unfortunately whilst I have ARC Alchemist (A310 and A380) hardware, I also can’t really do much performance wise as using PCIe 3.0 and no rebar… likewise flipping between Xe and i915

Marked submitting a bugreport as the solution, I had to move my laptop off of Tumbleweed for the time being but I left a small partition to re-test when I get the time. Thanks for the input everyone.
