Kinda cross-posting... What would be the way to run Alan Wake 2 on Lutris proper? With Path Tracing enabled. AMD 7800XT (lemm.ee)

So.. Yeah, I installed Lutris on my KDE Neon (based off of Ubuntu 22.04, which might have an outdated Mesa...not sure how to get a most recent one?). I'm getting the now well-known AMD issue with textures, where the FBI jackets are non visible, and the facial textures look a bit...flat/untextured. Performance is rather decent with rasterizing, but Path Tracing/RT is grayed out in settings, not available. Another user suggested Nobara, which is Arch/Fedora-based. This fixed the textures, at the cost of completely tanking the performance to around 10-15FPS. RT settings continue to be greyed out... Any idea of what am I doing wrong? My card should be fully capable of displaying RT graphics, right ? Even if not hitting a great framerate, I'd like to see it!

EDIT: Ok...Just to bring some sanity back, Windows DOES enable the path tracing, and I can see the performance hit depending on whether it's enabled or not, and it definitely plays with a rather high FPS if it's off. So...what's gimping my Linux experience? What can I try?

Thanks!

As you mentioned, you need the latest Mesa(ATM git master). With that I had no issues.

For ray tracing, the only thing which enables it for me is using the VKD3D_CONFIG=dxr11 environment variable, but it would get so slow in forest and around water that made me disable it.

Try setting VKD3D_CONFIG=dxr as a launch argument for the game

THIS. This is the solution I needed originally. Additionally, there were a bunch of OTHER issues. But if you want a game to recognize you have a RT-capable card, this is what you need to add in Lutris or any other launcher. Thanks!

Just wanted to say that it seems DXR is enabled by default in vkd3d version 2.11 https://github.com/HansKristian-Work/vkd3d-proton/releases/tag/v2.11
