rx 6650xt owner here, ray tracing isn’t worth it.
Control is the only game I’d describe as playable with RT.
Control 1080p high with medium RT (so only reflections RT) runs always under 60.
Ratchet and Clank: Rift Apart 1080p medium with RT reflections high (which is the minimum) and RT draw distance 1 (also minimum) I get between 20 and 30 fps.
Hogwarts Legacy 1080p medium with low RT reflections also ran like crap.
All this was tested on Arch Linux with the recent Mesa 23.2 which is the one that introduced RT by default and huge optimizations.
rx 6650xt is great for non-RT 1080p gaming and good enough for low-end 1440p gaming. You can get pretty much any game except Alan Wake 2 and Starfield to run at 1440p60 with medium or high settings, older games like War Thunder (max settings except MSAA) and GTA 5 (max settings except MSAA) run great at over 100fps except GTA 5 has some dips in traffic.
Overall I’d recommend 1080p high refresh rate for this GPU and you’ll have a great time with high settings, but if you for some reason have a bigger screen, the GPU runs 1440p60 fine with at least medium settings.
Are you using Lutris as a flatpak?
In that case you might need to allow Lutris access to the game folder using Flatseal.
In this case the problem would be that Lutris doesn’t have access to important dlls in the game directory, as the file picker dialog only gives Flatpak Lutris access to the file you selected.
