  • High: 2x rendering, 16x anisotropic filtering, bilinear output.

• Added an anisotropic filtering dropdown and a VSync toggle.
• Updated render-scale labels: 1x 720p, 2x 1440p, 3x 4K and 4x 5K.
• Corrected the separate host presentation limit that kept the 120 FPS mode capped at 60 FPS.
• Replaced the showroom camera's fixed time step with elapsed time to prevent accelerated car presentations at 120 FPS.
• Added explicit fullscreen and presentation cleanup on exit to address desktop HDR dimming.

• Added automatic Forza Plus 120 FPS physics-profile switching, with restoration of the previous profile when returning to 60 FPS.
