Dataminers have been busy at work snooping through the Xbox's Grand Theft Auto 6 preload files, and two recent discoveries are grounds for a bit of performance optimism.

Library files named amd_fidelityfx_loader_xbox.dll and amd_fidelityfx_upscaler_xbox.dll are both present in the package snooped by Tex2, who posted their findings on X.

These names match the terms found in Microsoft's FSR 4.1 GDK sample that was published last week, as pointed out by blue nugroho and Y1ng.

thanks to @Y1ng5dvv that find the equivalent dll on FSR 4.12 doc, possibly hinted that GTA VI indeed already ready with FSR 4.12 👀👀👀👀 https://t.co/Xo9sgMTltbNovember 10, 2026

While this certainly doesn't mean that AMD's FSR 4.1 is a lock for GTA 6 when it launches — or thereafter — it's good to know that there's at least the possibility of having the latest upscaling tech on board.

FSR 4 was a major update that moved AMD's upscaling tech from manual to machine learning. Instead of using spatial and temporal algorithms, it now uses neural networks.

The results? A clearer image with less ghosting, shimmering, and artifacts at the cost of a small amount of GPU overhead.

Microsoft and AMD sent out FSR 4.1 for Xbox developers on November 5, roughly two weeks after it kicked off with beta drivers for the Xbox Ally handhelds.

Compared to competing methods like NVIDIA DLSS and Intel XeSS , AMD FSR is quickly catching up. I think most people hold DLSS as the benchmark for what can be done with AI upscaling, but AMD's broad compatibility can't be forgotten.
