DLSS 5 Download: Official Links Only
We do not host any files on this site. Every link below goes to an official page.
Before you download anything, read this: one important file cannot be downloaded at all. We explain why below.
Official Download Pages
| Tool | Official source |
|---|---|
| OptiScaler | github.com/optiscaler/OptiScaler |
| OptiScaler + DLSSNR (DLSS 5 pass) | github.com/Dagherbou/OptiScaler_DLSSNR |
| DLSS Swapper | github.com/beeradmoore/dlss-swapper |
DLSS Swapper can also be installed through winget:
winget install --id=beeradmoore.dlss-swapper -eThese GitHub pages are the only official sources. The OptiScaler team has confirmed they have no official website.
The file you cannot download
Many people search for nvngx_dlssnr.dll. This is the DLSS 5 model file. You cannot get it from any mod page.
The developer has said it clearly. The file belongs to NVIDIA. It is not theirs to share. It comes from a driver package, and you must supply it yourself. You also need one copy in each game folder. There is no shared location for it.
So if a website offers you this file as a direct download, be careful. That is exactly how fake sites work.
How to check a file before you run it
Never trust a download blindly. Two checks take less than a minute.
Check the hash. Open PowerShell in your download folder and run:
Get-FileHash -Algorithm SHA256 .\filename.zipCompare the result with the hash shown on the official release page. If they do not match, delete the file.
Scan it. Upload the file to VirusTotal before you open it. It is free and takes seconds.
Quick safety rules
- Mods come as
.zipfiles, not.exeinstallers - Never turn off your antivirus to install a mod
- Never download a DLL from a comment or forum post
- These tools are free — any site asking for payment is a scam
