I’d done that a few days ago, but you’re right, not specifically to these suggestions. I tried the export VKD3D_DISABLE_EXTENSIONS=VK_EXT_mesh_shader VKD3D_FEATURE_LEVEL=12_0 VKD3D_SHADER_MODEL=6_5 %command% and variations of it. It reduced performance significantly, so would not suggest people on more recent Mesa versions try this anymore. When I looked into it, it seemed to mainly be in place for Mesa 22.x which was still lacking mesh shader support.

Thought I’d post an update. Performance is better now, playing in 1440p with FSR2 on Balanced, graphic settings on Medium. I’m getting around 45FPS.

I’m not quite sure what the fix was in the end, but I’ve installed proton-ge-custom-bin from the AUR, so I’ve got Proton GE installed onto my system (not just within Heroic). Both the AUR and Heroic are on Proton-GE 9.7. I then added the AlanWake2.exe file to Steam, and forced compatibility to use Proton GE. So whatever extra was happening with Heroic was taken away.

I tried changing my Mesa drivers, but it appears Manjaro is even with the nonfree repo at this point, so I’m still on Mesa 24.1.1, only on the Manjaro-approved version, not the mainline Arch version.

It appears that somewhere within that combination of (1) running the game directly from Steam, (2) using the system-installed Proton-GE package, and (3) reverting to the Manjaro Mesa package the framerate got bumped from lower 20-s to mid-40s. CPU and GPU usage still hover around the 40%, so I feel there would be more improvement to be had perhaps?

I tested the game on my second PC, which is running ChimeraOS, has a 5800X3D chip, 32Gb RAM and a 7600 XT card, where it’s easily hitting these framerates and better (but with higher GPU usage, hardly any CPU usage, that 5800X3D is a beast). So I wonder if my 10700K might be a bit of a bottleneck? ChimeraOS’ version of Mesa is on 23.2 so maybe there are just some kinks to be worked out in the 24.1 branch?

Anyway… long story short: I’m happy with the overall performance at this point. Happy to dive into the Overlap and deal with Nightingale!

Hi, I’ve checked but the Manjaro nonfree branch is the main one, just more up to date with the Arch main branch. Or are you suggesting a particular version?

These all sounds like good ideas to play with, thanks! I’ll have a go later tonight and will update here. It would be bonkers if the mesh shaders were at fault, since I got my 7800XT specifically for that feature…

Hi, sorry, the non-free is a very Manjaro-specific thing.

TLDR: They removed a lot of proprietary video codecs from Mesa, which means that Manjaro’s Mesa tends to lag behind the Arch repo. By using nonfree, the Mesa installation is pulled and compiled straight from Arch.

So yes, I’m using RADV through Mesa 24.1.1 instead of version 23.x (which is where Manjaro is still at). I wanted to be on a newer version since 24.x packed in a lot of 7000XT improvements.

Out of curiosity, have you tried AW2 with your 7800XT? How does it run for you?

I’ve been on Manjaro for about 1.5 years now too. I switched over to the Unstable branch a while back, which fixed this issue for me. This branch seems to be getting all packages at the same speed as regular Arch. Plus, I still get the Manjaro-specific kernels, access to their repos, integrated pamac, etc. For now, I’m sticking with Manjaro this way.
