With the launch of its RDNA 4 GPU architecture and FSR 4, AMD leveraged the power of machine learning to improve its upscale and frame generator. However, even if you rushed out to buy a new RX 9070 graphics card, your chance at checking out FSR 4 depended entirely on devs adding it to their games. With the release of the latest FidelityFX SDK, though, it appears that you can just do it yourself, by using one little app and a spot of file renaming.
That's according to the developer of DLSS Swapper, who remarked that a visitor to the app's GitHub stated that they managed to swap the FSR 3 files in a game and have it use FSR 4 instead. DLSS Swapper is a neat little tool that lets you change the DLL (dynamic linked library) files in a game's folders, so you can test out different versions of DLSS, FSR, and XeSS to your heart's content.
