Adding on, the GPU utilization is very low
Please make an apitrace.
I already looked at this, this is not a D3D-related issue at all, it's barely rendering anything, there are no weird thread/GPU syncs on our end and the CPU time spent in our code is like a single-digit percentage. Performance is even identical with wined3d. The game is just bottlenecked in its own code somewhere.
Just tried to run this with -force-d3d12 (yes, it actually works) and getting the exact same shitty performance there, so yeah.
@doitsujin That's interesting to me, thanks. I did this on my linux laptop too and gpu util was low and perf had issues but windows did not.
Maybe report it on the proton github tracker, if it's fast on windows then it's probably a wine issue.
Nothing extracted yet.
Raidou remastered on Steam Deck and other Linux-based systems have performance drops when any reflections are on screen. This can be seen in the opening cutscene and especially in battles.
