Two AMD FidelityFX dynamic link libraries have appeared in the software package metadata for the Xbox version of GTA 6, with file names matching the components used in the FSR 4.1.2 sample. This suggests that Rockstar Games may be using AMD's newer FSR development tools, but it cannot yet be confirmed whether the game actually enables FSR 4.
Information shared by data miner Tex2 reveals that the two files are named amd_fidelityfx_loader_xbox.dll and amd_fidelityfx_upscaler_xbox.dll. Subsequently, Y1ng and blue nugroho compared them with the FSR 4.1.2 sample recently released by Microsoft. Microsoft's documentation also mentions the loader file, which is used to load the upscaling library on Xbox consoles.
However, the relevant files for GTA 6 remain encrypted, making it impossible to determine which generation of upscaling technology the game utilizes based solely on file names. The latest AMD FSR SDK includes technologies such as FSR 3.1.6, FSR 4.1.2, frame generation, and ray regeneration. Microsoft's demonstration also allows developers to switch between FSR 3 and FSR 4 within the same integration.
AMD and Microsoft announced support for FSR 4.1.2 on Xbox Series X|S on November 4. This feature is provided through the October 2026 version of the Xbox Game Development Kit and includes two INT8 models optimized for consoles. The existing files indicate that Rockstar has the foundational tools to adopt or upgrade to FSR 4.1.2 in the future, but this does not prove that GTA 6 will launch with FSR 4 enabled.
