Editorial review: 5 October 2026 UTC. Official sources and one downloaded Windows installer were checked. Application execution, installation, antivirus scanning, game compatibility, performance benchmarks and restoration tests were not performed for this review.
DLSS Swapper is a free Windows tool for managing and replacing DLSS, FSR and XeSS libraries in supported game installations. It can be useful for a permitted single-player experiment with an older upscaling library, but it cannot add missing game integration or guarantee better image quality, FPS or stability.
Official version, download and price
The official GitHub release record currently identifies v1.2.6.1, published 26 August 2026, as the latest non-prerelease. Its notes add preset F for DLSS Ray Reconstruction. Start at the beeradmoore project README and its GitHub Releases link; the README also lists Windows Package Manager as an official installation route.
There is no purchase fee for the tool. Its GPL-3.0 license covers the project’s code, not a new license for NVIDIA, AMD or Intel DLLs. Library redistribution and each game’s rules remain separate. You still need an appropriately licensed game.
The winget community manifest directory currently lists 1.2.5.0 as its newest version, while GitHub lists 1.2.6.1. Check the version offered by your chosen route. Do not assume that running a package-manager command always installs the same build as today’s GitHub release.
Choose the release asset explicitly
The official v1.2.6.1 release page offers an installer and a portable ZIP. The installer asset is 114,898,480 bytes (114.90 MB); the portable asset is 119,973,583 bytes (119.97 MB). MB here means one million bytes. Older labels of 109.6 and 114.4 correspond approximately to binary MiB, not decimal MB.
We downloaded the named installer on 5 October and measured its SHA-256 against GitHub’s asset digest. Windows returned Valid / Authenticode / SignPath Foundation for that exact installer. The portable ZIP’s size and digest in this page’s file table are publisher metadata unless explicitly identified as measured evidence in the linked safety guide; this review does not transfer the installer’s signature result to the ZIP or DLLs.
Signature validity identifies a verified signer for those bytes; it is not a malware-free certificate, a code audit or proof of game compatibility. See the DLSS Swapper verification guide for the exact-file evidence and its limits. We do not host or repack either asset.
Windows and GPU requirements
The README specifies Windows 10 64-bit, 20H1/build19041, as the OS minimum, and lists any GPU for the library-management tool. This does not make NVIDIA DLSS run on every GPU: the game integration and the particular upscaler feature determine compatibility.
Windows 10’s compatibility minimum is separate from its support lifecycle. Read the ESU guide before continuing with that OS. For SR, RR, FG and MFG hardware boundaries and supported official alternatives, see DLSS Swapper versus NVIDIA App overrides.
When it fits, and when to stop
- Possible fit: a game permits library changes, already integrates the desired upscaler, and you want to compare one documented library version or preset.
- Stop: an online or anti-cheat policy prohibits unexpected game files. The repository owner’s warning says these changes can be flagged and lead to a ban.
- Stop: someone tells you to download a fix DLL from an issue comment, message or unaffiliated site, or to disable protection. A comment inside the real repository is still a third-party upload.
- Reconsider: your goal is adding DLSS to a game without integration, or unlocking a GPU-exclusive feature. Swapping a file does neither.
A controlled evaluation and recovery plan
Follow the project’s installation instructions for the chosen package. The tool detects several game launchers and permits manual additions, but recognizing a game folder does not certify replacement compatibility. Record its patch version, existing library and settings before modifying it.
Change one item at a time and compare the same scene and graphics settings. If it fails, the developer’s Reset instructions describe selecting the game’s DLL menu and restoring the original. A backup can be absent or outdated after a patch; launcher file verification can restore shipped files while removing other modifications. Preserve relevant mod configuration first.
These are proposed user checks, not a successful installation or recovery performed by us. Use the Windows hash and signature workflow and the official-source checklist for file provenance, while keeping game permission and real compatibility as separate decisions.
