This quick tutorial will show you how to enable the NVIDIA RTX Video Super Resolution in Mozilla Firefox.

As RTX Video Super Resolution utilizes the Tensor Cores present in NVIDIA GeForce RTX GPUs, it is exclusively compatible with graphics cards from the 30, 40, and 50 series.

If you’re using a recent version of Mozilla Firefox, this feature is likely already enabled by default. To confirm, you can check your settings (using the instructions below) to make sure.

Prerequisites

• Mozilla Firefox version 124 (or above)
• NVIDIA graphics card (30, 40, and 50 series only)
• RTX super resolution enabled via the NVIDIA Control Panel or the new NVIDIA App

• Open your Mozilla Firefox web browser and enter “about:config” in the search bar.

• Type in “gfx.webrender.super-resolution.nvidia” into the search box.

• Make sure the option is set to “true”.
