Affected applications

  • Mozilla Firefox

Issue description
RTX Video Super Resolution no longer activates during browser video playback. The NVIDIA App consistently reports the feature as Inactive and there is no visible upscaling effect.

This feature previously worked on this exact hardware and OS. No hardware changes were made.

Expected behavior
With RTX Video Super Resolution enabled, the feature should engage during browser video playback (for example YouTube 720p or 1080p fullscreen), as advertised for RTX 40-series GPUs on Windows 10.

Actual behavior

  • RTX Video Super Resolution always reports Inactive
  • No visible image quality improvement
  • Reproducible across browsers
  • Persists across reboots and clean driver installs

Critical control result
RTX Video Super Resolution functions correctly in the VLC RTX build on this same system.

This confirms:

  • RTX 4070 SUPER hardware support is intact
  • RTX VSR implementation exists in the driver
  • Windows 10 graphics stack is functional
  • Failure is isolated to browser video pipelines

Troubleshooting performed

  • NVIDIA Image Scaling disabled
  • DSR and DLDSR disabled
  • GPU scaling verified
  • Display running native resolution with PC timing
  • Output color format RGB Full
  • Hardware Accelerated GPU Scheduling tested at default
  • No TDR overrides present
  • No MPO override active
  • NVIDIA profile cache reset
  • NVIDIA App reinstalled
  • Driver reinstalled cleanly
  • Multiple browsers tested
  • Visual A/B testing confirms no effect

None of these steps restored browser RTX Video Super Resolution.

Regression context
RTX Video Super Resolution previously functioned on this system. The failure began without hardware changes.

Given that RTX VSR continues to function in VLC RTX and the issue is isolated to browsers, this appears to be a driver-level regression affecting browser video decode or swapchain injection on Windows 10 for RTX 40-series GPUs.

Request
Please clarify:

  • Whether browser-based RTX Video Super Resolution on Windows 10 is currently supported for RTX 40-series GPUs
  • Whether this behavior is a known regression
  • Whether a driver fix is planned
  • Whether a last-known-good driver branch exists where browser RTX VSR functioned correctly on Windows 10

I have the same issue on my laptop gaming running Windows 11 Pro 25H2 (Build 26200.7623) with a RTX 5070 Ti Max-Q 12GB with discrete GPU mode enabled, RTX VSR works on MPC-HC but no longer works on my Firefox browser since update 591.74 (BIOS, VBIOS and all other drivers up to date), in addition the “Video” tab has disappeared in NVIDIA App under “System” setting, but the video settings are still present from the old Nvidia control panel so I can manage RTX VSR, a recent bug has clearly impaired the proper functioning of the RTX VSR feature, just 2 weeks ago my 720p videos were correctly upscaled to 1440p on Firefox, today it no longer works.

P.S. : The RTX VSR indicator in the top right of my Firefox videos is huge and pixelated instead of being small, weird.

Edit: After uninstalling the graphics driver + NVIDIA App + cleaning the shader cache using the DDU software, I was able to find the RTX VSR settings in NVIDIA App, however it still does not work in my Firefox browser.
