DLSS to XeSS/FSR2 (2.1 & 2.2)

Drop-in DLSS replacement with XeSS/FSR2 for DLSS2 supported games.

Based on PotatoOfDoom's excellent CyberFSR2.

I have adapted it to use Intel's XeSS too.

With this branch:

• Added FSR 2.2.1 support for DX11 (Native or with DX12), DX12 and Vulkan
• Added FSR 2.1.2 support for DX11 (with DX12), DX12 and Vulkan
• Added ImGui in-game menu for DX11 & DX12 (Shortcut key is HOME)
• Added Unreal engine detection and autofixes
• Added FidelityFX CAS shapening support, you can enable and adjust it from ini file.

Supported backends:

• DX11 : XeSS (with DX12), FSR2 (native), FSR2 (with DX12)
• DX12 : XeSS (native), FSR2 (native)
• Vulkan : FSR2 (native)

Note: (with DX12) backends have a performance penalty (around %10-15).

Installation

Windows

• Download the latest relase from releases.
• Extract the contents of the archive next to the nvngx_dlss.dll file in your games folder.
• Copy the libxess.dll to your game executable directory.
• Run EnableSignatureOverride.reg and confirm merge.
• That's it. Now DLSS option should appear in settings if not you may try using d3d12-proxy for DirectX games and vulkan-spoofer for Vulkan games

Linux

• Download the latest relase from releases.
• Extract the contents of the archive next to the nvngx_dlss.dll file in your games folder.
• Copy the libxess.dll to your game executable directory.
• Run the linuxinstall.sh script
• Or just run the following command with the appropriate file paths to install the tweaks manually:

WINEPREFIX=/path/where/the/steam/library/is/steamapps/compatdata/1091500/pfx /bin/wine64 regedit ../../common/Cyberpunk\ 2077/bin/x64/FidelityFx\ Super\ Resolution\ 2.0-3001-0-3-1656426926/EnableSignatureOverride.reg

• That's it. Now DLSS option should appear in settings if not you may try using d3d12-proxy for DirectX games and vulkan-spoofer for Vulkan games
