Drop-in DLSS replacement with XeSS for various games such as Cyberpunk 2077.

Based on PotatoOfDoom's excellent CyberFSR2. I have adapted it to use Intel's XeSS

As XeSS officially only supports DirectX12 (Support for DirectX11 added but consider it as alpha and expect performance and other problems).

Added FidelityFX CAS shapening support, you can enable and adjust it from ini file.

• 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

• 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

• Just run DisableSignatureOverride.reg
• Linux users should refer to prior command.

• Visual Studio 2022

• Clone this repo with all of its submodules.
• Open the CyberXeSS.sln with Visual Studio 2022.
• Copy the compiled nvngx.dll from the XeSS Directory to your game executable directory.
• Copy the libxess.dll to your game executable directory.
• Run the EnableSignatureOverride.reg to allow DLSS implementation to load unsigned DLSS versions
• Run the game and set the quality in the DLSS settings
• Play the game with XeSS
