COMPARISON · DLSS TOOLS · CHECKED 8 NOV 2026
NVIDIA Profile Inspector, NVIDIA App, DLSS Swapper, DLSSTweaks and OptiScaler compared
Use NPI or the NVIDIA App when your game already has DLSS and you only want a newer model or preset: they change driver settings and leave game files alone. Use DLSS Swapper when you want a specific DLSS DLL file in the game folder. DLSSTweaks, OptiScaler and Special K load extra code into the game, which gives more control, and OptiScaler can bring DLSS-style upscaling to non-NVIDIA GPUs, but they carry real anti-cheat risk in online games.

What do you want?
How each tool works
| Tool | What it changes | Needs NVIDIA GPU | Undo | Anti-cheat exposure | Status |
|---|---|---|---|---|---|
| NPI | Driver profile settings, per game or global | Yes | Reset the row or import a backup | A driver setting, not a game file. No vendor statement. | Active, community project |
| NVIDIA App | Driver overrides for DLSS models and frame generation | Yes | Reset in the App | A driver setting, not a game file. | Official NVIDIA software |
| DLSS Swapper | DLL files inside game folders | No, it swaps files | Restore the original DLL | A changed game file. | Active, GPL-3.0 |
| DLSSTweaks | A wrapper DLL and an ini file per game | Yes | Remove the wrapper and ini | An injected DLL. | GitHub repo frozen, newer builds elsewhere |
| OptiScaler | A wrapper that routes upscaler calls | No | Remove the wrapper files | An injected DLL. | Active |
| Special K | An injection framework with many features | No | Uninstall it | Its own documentation warns of anti-cheat risk online. | Active |
CODE · project repositories DLSSTweaks does not use the driver profile database at all. It overrides how the game loads nvngx.dll. Its lead author, emoose, is also NPI’s lead developer.

NPI and the NVIDIA App
Both change the same kind of driver override. See NPI versus the NVIDIA App for how they differ.
Safety and anti-cheat
| Tool | What it leaves on the PC | Statement |
|---|---|---|
| NPI and NVIDIA App | A driver setting | NVIDIA does not mention anti-cheat in its DLSS override announcement. |
| DLSS Swapper | A different DLL in the game folder | None found. |
| DLSSTweaks, OptiScaler, Special K | Extra DLL files loaded by the game | Special K warns in its own docs. Others: none found. |
Can you combine them?
We tested none of the combinations. A driver override together with a swapped DLL or a wrapper can conflict, because they change the same library by different routes. If you combine them, change one thing at a time.
Where to get each tool safely
Use each project’s own GitHub page, listed in the sources. Lookalike sites exist for these tools too, as they do for NPI. See the NPI download page for how we verify downloads.
Questions people ask
Should I use DLSS Swapper or NVIDIA Profile Inspector?
Use NPI if you want the driver to supply a newer model or force a preset per game. Use DLSS Swapper if you want a specific DLL file placed in the game folder. They work at different levels and do not do the same thing.
Is DLSS Swapper safe?
It is an open-source program under the GPL-3.0 licence that swaps DLL files inside game folders. Changing game files can trigger anti-cheat in online games, and no vendor has said it is safe. Download it from its official GitHub page only.
Does OptiScaler work on AMD?
That is its purpose: it loads as a wrapper so a game's DLSS inputs can drive other upscalers on non-NVIDIA GPUs. We could not test it, and it is an injected library, which anti-cheat can flag.
Can I use DLSSTweaks online?
We would not. It loads a wrapper DLL into the game, which anti-cheat systems are designed to detect. Use it in offline games.
