OmniScaler (was CyberXeSS) is drop-in DLSS2 to XeSS/FSR2 replacement for games.

This project is based on PotatoOfDoom's excellent CyberFSR2.

Official Discord Server: DLSS2FSR

How it works?

OmniScaler implement's all necessary API methods of DLSS2 & NVAPI to act as a man in the middle. So from games perspective it's using DLSS2 but actually using OmniScaler and calls are interpreted/redirected to XeSS & FSR2.

Features

• An in-game menu for tuning and saving settings (Only on DirectX 11 & DirectX 12 APIs)
• Full integration with DLSS Enabler for DLSS-FG support
• Fidelity FX CAS (Contrast Adaptive Sharpening) support for XeSS to mitigate relatively soft image upscaler generates
• A supersampling option for backends running on DirectX 12
• Autofixing colored lights on Unreal Engine & AMD graphics cards
• Autofixing wrong motion vector informations and reducing ghosting on these games
• Autofixing missing exposure texture information
• Ability to modify MipmapLODBias value of game

Which APIs and Upscalers are Supported?

Currently OmniScaler can be used with DirectX 11, DirectX 12 and Vulkan but each API has different sets of upscaler options.

For DirectX 11

• FSR2 2.2.1 native Direct11 implementation (Default upscaler)
• XeSS 1.x.x with background DirectX12 processing [*]
• FSR2 2.1.2 with background DirectX12 processing [*]
• FSR2 2.2.1 with background DirectX12 processing [*]

[*] This implementations uses a background DirectX12 device to be able to use Dirext12 only upscalers. There is %10-15 performance penalty for this method but allows much more upscaler options. Also native DirectX11 implementation of FSR 2.2.1 is a backport from Unity renderer and has it's own problems which some of them avoided by OmniScaler.

For DirectX 12

• XeSS 1.x.x (Default upscaler)
• FSR2 2.1.2
• FSR2 2.2.1

For Vulkan

• FSR2 2.1.2 (Default upscaler)
• FSR2 2.2.1

Installation

• Download the latest relase from releases.
• Extract the contents of the archive next to the game executable file in your games folder. [1]
• Run EnableSignatureOverride.reg and confirm merge. [2][3]
• DLSS option should be appeared/enabled in games settings. If it's not, you may try using d3d12-proxy for DirectX games, vulkan-spoofer for Vulkan games and nvapi-dummy for spoofing NVAPI.

[1] This package contains latest version of libxess.dll and if game folder contains any older version of same library it would be overwritten. Consider backing up or renaming existing file.

[2] Normally Streamline and games check if nvngx.dll is signed, by merging this .reg file we are overriding this signature check.

[3] Adding signature override on Linux - There are many possible setups, this one will focus on steam games:

• Make sure you have protontricks installed
• Run in a terminal protontricks regedit, replace with an id for your game
• Press "registry" in the top left of the new window -> Import Registry File -> navigate to and select EnableSignatureOverride.reg
• You should see a message saying that you successfully added the entries to the registry

If your game is not on Steam, it all boils down to opening regedit inside your game's prefix and importing the file.

Uninstallation

• Run DisableSignatureOverride.reg file
• Delete EnableSignatureOverride.reg, DisableSignatureOverride.reg, nvngx.dll, nvngx.ini files
• If there were a libxess.dll file and you have backed it up delete the new file and restore the backed up file. If you have overwrote old file DO NOT delete libxess.dll file. If there were no libxess.dll file it's safe to delete.
