Edit: It’s a single threaded render thread issue that is common with many UE4 games.
I’m bringing this up because my Ryzen 5 3600X machine seems to have no bottlenecking issues with DXVK and UE4, but my 4960X, a pre-AVX2 CPU, seems to be bottlenecking like crazy at all resolutions…
The specific game is Breathedge, which got a big map update recently that sees my framerate dip to 30fps at ALL resolutions on non-AVX2 CPUs. Native Windows though doesn’t see this problem on non-AVX2 CPUs.
Could it also be Wine vs Proton? I just don’t understand why one has such a performance deficit because they use the same Vulkan driver and I’m using an identical GPU.
Could it be
LC_ALL=C? That’s the difference between my 3600X machine and my 4960X machine.
