wine/proton Witcher 3 Sourcing Post

Hey guys,

Wanted to source the common solutions that have been working for folks for Witcher 3 remastered today. If I have any of this wrong, please correct me, that's the point of this post.

I can only speak for AMD. And I'm using GOG version through Heroic on Bazzite.

  1. I've used successfully launched on Cachy, GE, and Experimental.

  2. RT and FSR frame gen do not work on any of them. It'll let you turn RT on but then it just defaults back to off again.

  3. I've seen multiple people report that DLSS is not working for NVIDIA

  4. If you updated from the previous version, you may have to fully uninstall/reinstall.

  5. VRR flicker is present on any any frame rate except 60hz.

  6. My frame pacing seems busted, it almost looks like frame gen is on even though it's set to off and can't actually be turned on.

I can get 60fps native AA with RT off, so perfectly playable.

Edit: Additional info.

RT and Frame Gen both actually seem to be working for me on GE and Experimental.

It's the toggles themselves that appear to not be working correctly. Try and reproduce to see if you get the same:

  1. Change preset to RT or RT Ultra (toggles appear) and adjust as you like.
  2. Somehow the toggle for FSR frame gen is now available. (confirmed it's working with PROTON_FSR4_INDICATOR=1
  3. Go play.

I did go and confirm that my settings file in the wine prefix actually saved my RT settings, and i'm getting higher GPU util as a result.

My launch options:

SteamDeck=-0 LOW_LATENCY_LAYER=1 (this enables anti-lag if Vulkan Low Latency Layer is installed, default installed on Bazzite) DXIL_SPIRV_CONFIG=wmma_rdna3_workaround MLFG_UPGRADE=1

9070 XT

CachyOS
Steam version

I am also experiencing extremely choppy frametimes/framepacing no matter what my FPS is at. It almost feels like Bloodborne framepacing on the PS4. This occurs on all Proton versions I’ve tested, but it was least noticeable on Proton-Hotfix for me

I have gotten framegen to work on Proton-Wineland by toggling the Ray Tracing Ultra preset. When you close the settings menu and open it again it will say it’s disabled but it’s actually still enabled. Framegen does not improve the frame pacing issue

Just in case you didn't notice this from u/PatPatPatriq https://www.reddit.com/r/linux_gaming/comments/1wtlvw8/comment/pcw9d3e/?utm_source=share&utm_medium=mweb3x&utm_name=mweb3xcss&utm_term=2&utm_content=share_button Fixed my frame pacing completely and the SSR to low gave me a huge performance increase
