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 Yeah, I installed Lutris on my KDE Neon (based off of Ubuntu 22.04, which might have an outdated Mesa...not sure how to get a most recent one?).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!

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!
