Two AMD libraries in GTA VI's Xbox Series X|S package match the file names in Microsoft's brand new FSR 4.1.2 sample. Rockstar hasn't said a word about FSR, and the same files also support the older FSR 3, but it's the first hint that Xbox could get machine learning upscaling in Vice City.
GTA VI’s Xbox version may be packing AMD’s newest upscaler. Two files inside the game’s Xbox Series X|S package, spotted in metadata shared by Rockstar dataminer Tex2, match the names Microsoft uses in its new FSR 4.1.2 integration for Xbox, VideoCardz reports. The files are amd_fidelityfx_loader_xbox.dll and amd_fidelityfx_upscaler_xbox.dll.
The link was made by X users Y1ng and blue nugroho, who compared those names with Microsoft’s FSR 4.1.2 sample documentation. That documentation specifically names amd_fidelityfx_loader_xbox.dll as the file that loads the upscaler on Xbox consoles.
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/nVemtp633h pic.twitter.com/Xo9sgMTltb

What this does and doesn’t prove
This is a rumor, and the fine print matters. FSR is now a family of tools, not one upscaler. The same AMD SDK covers FSR 3.1.6, FSR 4.1.2, frame generation and ray regeneration, and Microsoft’s own Xbox sample lets developers switch between FSR 3 and FSR 4 through the same integration. So the presence of these files proves Rockstar is using AMD’s current FidelityFX SDK on Xbox. It does not prove GTA VI will launch with FSR 4 switched on. VideoCardz also notes the game’s files are encrypted, so nobody can say for sure which upscaler is running.
Rockstar’s official word on November 10 didn’t settle it. It confirmed PSSR upscaling and ray-traced shadows on PS5 Pro and a 30 FPS target on every console, as we covered in our 30 FPS story. It said nothing about FSR on Xbox.
Why Xbox fans should care anyway
Here’s why this is worth watching. FSR 4 is a machine learning upscaler. Older FSR versions use hand-tuned math to sharpen a lower resolution image. FSR 4 uses a trained model and data from multiple frames to rebuild detail, which is the same basic idea behind PSSR and Nvidia’s DLSS. Xbox’s Jason Ronald announced on November 4 that FSR 4.1.2 is available to developers on Xbox Series X|S, with a Full model and a lighter Lite model built for each console.
If this rumor is true, does FSR 4 change your GTA 6 plans?

GTA VI is 30 FPS on every console, so this isn’t about frame rate. It’s about image quality. If Rockstar flips on FSR 4 at launch or patches it in later, Xbox Series X and especially Series S players could get a sharper, cleaner Vice City from the same hardware. VideoCardz points out that the new SDK makes a later upgrade possible without reworking the whole integration, so even a launch on FSR 3 would leave the door open.
Our read: the timing is hard to ignore. Microsoft and AMD put FSR 4.1.2 in developers’ hands two weeks before the biggest launch of the generation, and the game’s Xbox package already carries the matching loader. That’s a sign Rockstar is at least set up for it. But “set up for it” is not “confirmed,” and Sony owners got a press release about their upscaler while Xbox owners got file names. We’d love for Rockstar or Xbox to just tell people.
Until then, file this as a strong maybe. We’ll update this story the moment Rockstar confirms which upscaler GTA VI uses on Xbox. GTA VI launches November 19 on Xbox Series X|S.
