dlssg-to-fsr3 mod with Proton

[Zenzi0]

Feature Request

I confirm:

• that I haven't found another request for this feature.
• that I have checked whether there are updates for my system available that
  contain this feature already.

Description

Is it possible to use this mod with Proton? It replaces Nvidia Frame Generation with FSR3 in games like Cyberpunk 2077, The Witcher 3 and others.

A RTX graphics card is required. From what I've read one needs to place both .dll files into the folder with the game's executable (make a backup of the original dbghelp.dll). In game one needs to disable V-Sync. Another comment here recommends to enable Hardware-Accelerated GPU Scheduling (in Windows). I don't know whether that is possible in Linux.
This could be a massive improvement for Nvidia graphics cards older then 40XX gpus.

Edit: They have since changed the installation instructions and the file names. Here are the instructions at the time of writing:
dlssg-to-fsr3 has been tested in Cyberpunk 2077 and The Witcher 3 only.

dlssg-to-fsr3 may be obtained from: https://github.com/Nukem9/dlssg-to-fsr3

================================
===== Install instructions =====

1. Right click on "DisableNvidiaSignatureChecks.reg" and select "Merge". Click "Yes" when the dialog opens.

2. Locate your game's installation directory. For Cyberpunk 2077, this would be the folder containing Cyberpunk2077.exe.

3. Copy "dlssg_to_fsr3_amd_is_better.dll" and the new "nvngx.dll" to your game's installation directory.

4. Done. Launch the game. You'll see a message box on startup.

================================
==== Uninstall instructions ====

1. Right click on "RestoreNvidiaSignatureChecks.reg" and select "Merge". Click "Yes" when the dialog opens.

2. Delete "dlssg_to_fsr3_amd_is_better.dll" and "nvngx.dll" in your game's installation directory.

Wine currently does not support the APIs Streamline uses to check if Hardware Accelerated GPU Scheduling is enabled. I have a hack for this here which should apply to Wine 9.0-rc2 and some flavors of it.

Warning though, some assembly is required; you will need to compile your own Wine to use this (don't forget to run tools/make_specfiles before building, otherwise linking will fail). It seems to be working for me in Cyberpunk 2077 (you will need to export WINEHAGS=1 environment variable to enable it).

[Zenzi0]

Maybe it is time to learn how to build packages and include patches then.
But isn't something like this what a project like GloriousEggroll's proton-ge-custom would be willing to include? At least until a non-hacky alternative presents itself. I don't possess the knowledge to judge this accurately.

Thanks, it works. But I actually had to patch gpu detection to get dlss to work.

Could u say how to do it step by step :3 ?

Well I gonna try both patches on my machine and report back.
Just need to wait for the compile to end, the patches applied to wine-proton-9999 without problems:

[Saancreed]

Don't forget to also apply the second patch from my gist, the hags-0002.patch one.

[MrDuartePT]

Well after adding the missing path and editing the ebuild to add tools/make_specfiles now should work.

[MrDuartePT]

@Saancreed it work but create graphical corruption:

Edit: Turnning off dlss frame generation the bug disappear.

Pausing the game or staying still the color return to normal:

I gonna try removing some env to see if solves it:

Ok didnt solve. Can be a bug with wine since is a rc version

This is the same result people got on Windows on GTX cards when using my nvapi-dummy (based on dxvk-nvapi) to spoof the GPU arch.

[FakeMichau]

@MrDuartePT Would you mind sharing your dxvk-nvapi log?

@MrDuartePT Would you mind sharing your dxvk-nvapi log?

Well I only could generate the VKD3D logs lets see if this helps:
cyberpunk-vkd3d.txt

And I using a RTX 3070 Mobile (laptop) is very strange this is happening

Why is an Nvidia GPU required, when FSR is explicitly designed by AMD to be largely hardware agnostic?

Because it uses DLSS, which is Nvidia only. It only uses the Frame gen component from FSR3.
