Have you tried this?

> To enable it, launch the NVIDIA Control Panel and open “Adjust video image settings.” Check the super resolution box under “RTX video enhancement” and select a quality from one to four — ranging from the lowest impact on GPU performance to the highest level of upscaling improvement.

From what I can see on Reddit it's just not working for some people - I can't see the difference on my desktop no matter what I try.

You need to set the video source lower than your monitor resolution and possible set chrome to high power mode (details here: https://nvidia.custhelp.com/app/answers/detail/a_id/5448). Maybe that'll help you - it hasn't for me.

I had to turn it on manually under Nvidia control panel. My GPU used roughly 100W more while playing a video on any of the super resolution settings, so it is definitely working when turned on. I didn't do rigorous testing of video source quality though.

The idea is cool, but I'm going to leave it off since I don't think I'll get much benefit out of it.

I tried it on my Ryzen laptop and was able to work. You need to use 360p video and apply the settings and then restart the video for it to kick in. To really tell a difference, you'll want to compare screen captures.
