DLSS Swapper 1.2.3.1 Launches, Adding Full Support for DLSS 4.5

A fresh update to DLSS Swapper is here, giving PC gamers an easy way to upgrade image upscaling in their favorite titles even when official game patches haven’t arrived yet. If you’re looking to replace older upscalers with newer NVIDIA, AMD, or Intel versions through a simple interface, this tool remains one of the most convenient options available.

The newly released DLSS Swapper version 1.2.3.1 expands support for DLSS 4.5 by adding the Presets L and M. This matters because DLSS 4.5 introduces a second-generation Transformer model, which can deliver noticeably better clarity compared to earlier Transformer-based releases. With Presets L and M now available inside the tool, you can fine-tune the balance between visual quality and performance depending on what you care about most—whether that’s higher resolution sharpness, steadier frame rates, or a mix of both.

There is an important caveat, though: DLSS 4.5 can be more demanding than previous options. Older GPUs may take a clear performance hit when moving to the newer model. On newer graphics cards—particularly NVIDIA’s RTX 50 series with ample VRAM—the impact should be smaller, making DLSS 4.5 a more practical upgrade if you’re chasing improved image quality without sacrificing too much performance.

Another key detail for anyone planning to use the new presets: global preset selection in DLSS Swapper might not apply Presets L and M correctly right now. The developer describes this as an NVIDIA driver-related issue, which means you may need to set these presets per game rather than relying on a global configuration.

Beyond the DLSS 4.5 additions, version 1.2.3.1 also includes multiple bug fixes and updates to GameAsset enums to maintain compatibility with original configurations. For users who regularly swap upscalers across multiple games, these under-the-hood fixes should make the experience smoother and more reliable.

If you’ve been waiting to try DLSS 4.5 features in games that haven’t officially updated yet, or you simply want more control over DLSS presets, this DLSS Swapper release makes it much easier to experiment—just keep performance demands and the per-game preset limitation in mind.
