Spoofing
Except from first generation of DLSS2 games they all have some kind of NVidia verifying to enable DLSS option.
To bypass these checks modders have developed some tools.
Windows
Nvapi
For spoofing Nvapi calls FakeNvapi can be used. This is needed for enabling DLSS support for some games (like Shadow of the Tomb Raider etc.)
Also as a big bonus with latest releases FakeNvapi added support for AMD's AntiLag 2 & LatencyFlex to reduce input latency on games that supports Nvidia's Reflex.
Usage
Just put nvapi64.dll next to OptiScaler and set OverrideNvapiDll=true from OptiScaler.ini. This only works when OptiScaler is working as non-nvngx (not as nvngx.dll).
For using without OptiScaler:
You need to put nvapi64.dll file to your %WINDIR%\System32 but be careful!
- If you are an Nvidia user backup your original file and restore after mod usage is over.
- Do not use this mod with online games, it might cause anti cheat issues or banning.

DXGI
OptiScaler have built-in DXGI spoofing option which is enabled by default when working as non-nvngx (not as nvngx.dll).
d3d12-proxy
Alternatively for spoofing DXGI adapter checks d3d12-proxy can be used. This mod reports your GPU as RTX 4090.
Usage
Just place dxgi.dll file next to games executable.
Link
Vulkan
OptiScaler have built-in Vulkan spoofing options when working as non-nvngx (not as nvngx.dll).
Vulkan spoofing by default disabled and should be enabled from OptiScaler.ini when needed.
; Enables Nvidia GPU spoofing for Vulkan
; true or false - Default (auto) is false
Vulkan=auto
; Enables Nvidia extension spoofing for Vulkan
; true or false - Default (auto) is false
VulkanExtensionSpoofing=auto
vulkan-spoofer
Alternatively for spoofing GetPhysicalDeviceProperties checks vulkan-spoofer can be used. This mod reports your GPU as RTX 4090.
Compatiblity is a bit hit and miss, works for No Man's Sky (not working with latest streamline patch) but not working with Doom Eternal.
Usage
Just place version.dll file next to games executable.
Link
Linux
On Linux with you can use Wine & DXVK's embedded spoofing mechanisms.
DirectX & Vulkan
For DXGI & Vulkan spoofing just create a dxvk.conf file next to game's executable with this content or just download it from here.
dxgi.customVendorId = 10de
dxgi.hideAmdGpu = True
dxgi.hideNvidiaGpu = False
dxgi.customDeviceId = 2684
dxgi.customDeviceDesc = "NVIDIA GeForce RTX 4090"
NVAPI
For spoofing NVAPI with Proton set this envvar PROTON_FORCE_NVAPI=1
Goghor's DLSS Unlocker's
Goghor have created DLSS Unlocker mods for a lot of games which can be found on his Nexus profile.
For example as far as I know for Doom Eternal still only way to enable DLSS is his mod.
