Yeah, it was probably a coincidence you’re right. So far I’ve not been able to justify the expense of something equivalent to the 2080ti. I just live with the flicker whenever I work on my Linux desktop. Which isn’t often, too much work and not enough brain.
I upscaled some old porn movies using this, but my 2080ti started flickering afterwards. Probably better to use the free Google resources: github.com/k4yt3x/video2x
