Use DLSS Swapper with MSFS 2024 safely: find the correct PC install, replace the DLSS library, verify it, and restore it if problems appear.
On PC, use DLSS Swapper with Microsoft Flight Simulator 2024 by closing the simulator, selecting its detected installation, downloading a signed NVIDIA DLSS library, applying that version, then relaunching and enabling DLSS Super Resolution in the graphics settings. Keep the original DLL backed up so you can restore it after crashes, artefacts or an update.
DLSS Swapper setup steps for MSFS 2024
The safe method is to let DLSS Swapper replace the Super Resolution DLL in the active game folder, not to copy files into an MSFS package folder.
- Confirm that you are on a compatible PC. DLSS requires an NVIDIA RTX graphics card. DLSS Swapper cannot modify the Xbox or PlayStation versions of MSFS 2024.
- Close MSFS 2024 completely. Check that the simulator is no longer running before replacing its library. Leaving it open can prevent the file change or cause a partial replacement.
- Select MSFS 2024 in DLSS Swapper. Refresh the detected game list and choose the installation you actually launch. If several copies appear, check the drive and installation folder rather than assuming the first entry is correct.
- Back up the stock library. The Super Resolution file is normally named
nvngx_dlss.dll. Even if the utility records the previous version, copy that original file to a separate backup folder before changing it. - Download the required DLSS version. Use a library that the utility identifies as digitally signed by NVIDIA. A DLL is executable code, so do not substitute an unknown file taken from an unrelated archive.
- Apply the library to the game. Select the downloaded version and run the swap. Reopen the MSFS 2024 entry afterwards and confirm that the reported installed version has changed.
- Enable DLSS in the simulator. Launch MSFS 2024 and select NVIDIA DLSS Super Resolution in its graphics options. Keep the same resolution and quality preset during the first comparison; our guide to choosing an MSFS 2024 DLSS preset covers the next adjustment.
- Test one controlled flight. Use the same aircraft, airport, weather, camera and graphics settings. Examine glass-cockpit text, runway markings, moving propellers and frame pacing before deciding whether the swap helped.
Do not place nvngx_dlss.dll in the Community folder, rolling cache or downloaded content folders. The relevant copy sits with the PC game installation and is loaded by the simulator executable.
What does DLSS Swapper actually change?
A normal DLSS Swapper operation changes the NVIDIA Super Resolution library, but it does not rewrite MSFS 2024 or automatically unlock every feature carrying the DLSS name.
| Feature | What controls it | Effect of a Super Resolution swap |
|---|---|---|
| DLSS Super Resolution | The in-game upscaling setting and nvngx_dlss.dll | The replacement library directly affects image reconstruction. |
| Frame Generation | A separate game setting, library and compatible hardware | It is not updated merely by changing the Super Resolution DLL. |
| Newer DLSS features | The game integration, driver, GPU and relevant library | A replacement file alone cannot expose an unsupported feature. |
Some DLSS Swapper releases display separate library types. Treat each one independently and do not assume that swapping Super Resolution also changes Frame Generation. Our explanation of how DLSS 4 features are exposed in MSFS 2024 covers that distinction in more detail.
Why does MSFS 2024 not appear in DLSS Swapper?
MSFS 2024 usually goes missing because the utility has not indexed that storefront installation, the game is on another drive, or the wrong content folder has been selected.
- Launch the simulator once, close it fully, then refresh or rescan the game libraries.
- Use the PC launcher's installation-management screen to locate the real game folder. Do not point the utility at Community, downloaded packages or the rolling cache.
- If the installed utility supports manually added games, select the folder containing the simulator executable and its existing NVIDIA DLL.
- If Windows reports access denied, confirm that no simulator process is running. Do not take ownership of protected Windows system folders merely to force a swap.
- If that release of DLSS Swapper cannot recognise the installation, use a trusted build that supports its storefront rather than replacing similarly named DLLs at random.
How do I undo a DLSS swap?
Restore the original library through DLSS Swapper, copy back your backup, or use the PC launcher's repair or file-verification function.
- Close MSFS 2024.
- Reapply the original version recorded before the change, or return the backed-up
nvngx_dlss.dllto its original location. - Repair the installation if necessary. File verification normally restores the official game library when no usable backup remains.
- Rescan and test. Confirm the stock version is present before changing any other graphics or driver setting.
Common failure modes
- Crash or black screen: restore the stock DLL first. Do not combine a library swap with several driver and graphics changes because that hides the cause.
- Blurred instruments or unstable detail: verify that DLSS is enabled and test the same preset used before the swap. Our DLSS blur and failure checks cover sharpening, resolution and safe restoration.
- Ghosting behind displays, propellers or aircraft: compare against the stock DLL and TAA. Use these checks for diagnosing DLSS ghosting before keeping the replacement.
- No frame-rate improvement: a newer reconstruction library is not an automatic performance upgrade. MSFS may be limited by the main CPU thread, and Super Resolution is separate from Frame Generation.
- The swap disappears after an update: game updates and file verification can restore the official DLL. This is expected, so check the installed version again after updating MSFS 2024.
Should I always install the newest DLSS DLL?
No. Keep the stock DLL unless another signed version fixes a specific image-quality problem or behaves better on your system without introducing instability.
Change only the library, repeat the same test flight, and compare cockpit text, distant geometry, motion artefacts and frame pacing. Keep the swapped version when the improvement is clear and repeatable; return to the official file when there is no visible benefit, new ghosting appears, or the simulator becomes less stable.
