After downloading the Cyberpunk 1.62 update, Ray Tracing stopped working for me. I'm on Linux.

After downloading the 1.62 Cyberpunk update, Ray Tracing stopped working and crashes my game. I'm unable to get pass the initial warning screens if RT was on before coming back from a crash. I'd have to remove Ray Tracing related run arguments in Steam Play in order to play again.

The only way I'm able to play the game is by switching off Ray Tracing. Before 1.62 I was enjoying ray tracing effects with no issues.

Scenarios:

1. If I'm running the game and switch on RT, the game locks up and I need to restart the game.
   1. Once I restart the game and if RT was left on before crashing, I won't get pass the title screen.

Try running the game with PROTON_ENABLE_NVAPI=0. You'll lose DLSS (if you were using it) but can use FSR instead. Path tracing works too, if you're interested (my laptop with a mobile 3070 and FSR Balanced manages 9,5FPS on the benchmark)

Since we have a Linux thread here: Is there any chance to get RT (pathtracing or not) working on Linux with AMD cards? I can't test it as I only have a 5700XT.

Assuming you use Mesa/radv: the bits and pieces to have working RT in Cyberpunk on AMD cards under Linux are fairly new, and as far as I know there is no official Mesa release yet that includes them. You can check whether your distribution offers more recent Mesa packages ("mesa-git" or similar), or you can build Mesa from source yourself and point the game towards it (that's easier than it sounds, and it does not overwrite your existing Mesa install or affect your system). The game works and effects render properly, but performance is bad.

However.... with patch 1.62 RT on AMD cards on Linux is broken again for different reasons and the game won't launch. If you still have 1.61 around you can test it with that.

That did the trick! Thanks a lot. I was using DLSS but after you mentioned it, tried FSR and the Intel one. Went with the Intel option, works amazingly!
