I set this up today on my work laptop with (internal) RTX3060. According to the status indicators on the Adjust Video Image Settings page in the Nvidia control panel, super resolution is working in Chrome v124.x and v125.x but not at all in Firefox v126.0. My eyes tell me the same thing. I was able to play a 480p YT stream in Chrome and it looked surprisingly good on my external 1440p monitor. In FF it looks like ass. I may set up a secondary profile in FF just to make sure I haven’t changed some config setting over the years that would prevent it from working right in FF. Will update if I find anything interesting.
Edit: Just tried this again with YouTube in FF v126.0 with a clean profile. It does work, but only when the video is full screen (which makes sense I guess, but the behavior is different from Chrome) and I had to manually set the quality level in the Nvidia control panel. In Chrome the auto setting used level 4 (the highest level), but in FF the auto setting only used level 1.
Weird. I’m on desktop with an RTX 3080 and both super resolution and HDR are working just fine for me in both full screen and not. Results are actually quite good for me.
I think the default setting for auto depends on source resolution and desired display resolution from what I can see, so it’s variable depending on how and what you’re watching.
Interesting - I’m running the same driver version but on latest version of Windows 10 Pro. In FF, under about:config, is gfx.webrender.enabled or gfx.webrender.all set to true? If not, that might be part of it.
On the new clean profile I created in v126.0, I didn’t have a gfx.webrender.enabled and gfx.webrender.all was set to false. Changing gfx.webrender.all to true didn’t really change the behavior. Nvidia control panel only shows super resolution active when full screen. Watching the same test video as yesterday at the same requested resolution. I did notice that if I set the Quality back to auto, with gfx.webrender.all = true, it picked 2 today instead of 1. 🤷♂️

You on Windows 10 or 11?
Sorry. Should have mentioned. OS is Windows 11 Pro 23H2 22631.3593. Also, video driver is Nvidia Game Ready Driver 552.44.
