This app is not free! But i thought it was worth a mention.
The latest feature allows you to use Lossless Scaling to generate additional frames in games that do not have such support, including emulators.
Lossless Scaling is also useful for upscaling modern games if you cannot run them at native screen resolution (GPU limited) and want to get rid of blur due to bilinear scaling of the GPU driver, as well as for upscaling older and pixel-art games which do not support modern screen resolutions or full screen mode.
For modern games it is best to use LS1 or AMD FSR. For scaling pixel-art games, use Integer Scaling or xBR. Anime4K is best suited for cartoons or anime.
OptiScaler is a tool that lets you replace upscalers in games that already support DLSS2+ / FSR2+ / XeSS, now also supports enabling frame generation (through OptiFG or Nukem’s dlssg-to-fsr3).
While previously only DLSS2+ inputs were supported, newer versions also added support for XeSS and FSR2+ inputs (with some caveats 1 ). For example, if a game has DLSS only, the user can replace DLSS with XeSS or FSR 3.1 (same goes for an FSR or XeSS-only game). It also offers extensive customization options for all users, including those with Nvidia GPUs using DLSS.
Enables usage of XeSS, FSR2, FSR3, FSR4 2 and DLSS in upscaler-enabled games.
OptiScaler implements the necessary API methods of DLSS2+ & NVAPI, XeSS and FSR2+ to act as a middleware. It interprets calls from the game and redirects them to the chosen upscaling backend, allowing games using one technology to use another one of your choice.
