Deck Wizard released comparison videos demonstrating AMD FSR 4 performance against FSR 3.1.5 on Steam Deck hardware. Final Fantasy VII Rebirth and Stellar Blade serve as test subjects for the analysis. The newer upscaling technology produces cleaner and sharper visuals despite reduced frame rates. Both titles perform optimally at 60 frames per second, particularly Stellar Blade due to its action-heavy mechanics. Early results indicate strong potential for future optimization improvements.

AMD FSR 4 represents the first fully artificial intelligence-driven version of the upscaling software. The technology follows similar approaches used by NVIDIA DLSS and Intel XeSS through machine learning algorithms. RX 9000 series graphics cards receive official support for the feature. Modders discovered methods to enable FSR 4 on older RDNA 3 and RDNA 2 hardware through leaked source code. OptiScaler and similar tools facilitate manual implementation on unsupported systems, delivering enhanced image quality despite performance penalties.
