Dataminer Tex2 discovered amd_fidelityfx_loader_xbox.dll and amd_fidelityfx_upscaler_xbox.dll in the GTA 6 Xbox installation package. These files match the naming convention for FSR 4.1.2, which AMD and Microsoft released for Xbox consoles on November 4, 2026.
FSR 4.1.2 is the first machine-learning-based upscaler for Xbox, optimized for RDNA-2 GPUs via the October 2026 GDK. It offers Full and Lite INT8 models, with the Full model requiring 3.86ms at 4K on Series X. The SDK also includes the non-AI FSR 3.1.6 version.
While Rockstar Games has not officially named the upscaling tech for GTA 6, these encrypted files suggest a high-end integration for the November 19, 2026, launch. The game is coming to PS5 and Xbox Series X|S, but no PC version has been announced yet.
