Xbox PC In-game Fsr Not Applying Internal Scaling (stuck At Native) On Rx 7800 Xt / Dx12

Hi everyone,

I am reporting an issue with AMD FSR in Train Sim World 7 on PC (Xbox App / Windows Store version) running under DirectX 12.

Even with FSR enabled and set to "Performance" in the in-game Advanced Settings, the game remains stuck at 100% native render resolution. There is no change in visual downscaling and zero performance improvement.

System & Setup details:

• Platform: PC Game Pass / Xbox App (WindowsGDK install path via WindowsApps)
  
  
• GPU: AMD Radeon RX 7800 XT (Adrenalin Edition)
  
  
• API: DirectX 12
  
  
• Display Mode: Borderless Fullscreen (no exclusive fullscreen toggle)
  

Key Observations:

1. In-game FSR set to Performance does not reduce the internal render target.
   
   
2. The AMD Software driver panel displays an alert on "AMD FSR Scaling": "Mise à l'échelle inactive : Activez FSR 3.1 ou résolution inférieure dans le jeu" (Inactive scaling: Enable FSR 3.1 or lower resolution in-game), confirming the driver does not detect any active internal viewport scaling from the game engine.
   
   
3. Standard Unreal Engine workarounds via Engine.ini (like forcing r.FSR.Enable or r.ScreenPercentage) do not apply, as the Xbox PC / WindowsGDK filesystem virtualization discards or ignores these local configuration overrides.
   

Is anyone else on the Xbox PC version experiencing this FSR hook issue, and is an official patch planned to address the FSR implementation on GDK builds?

Thanks!
