Oh, well I limit to 60 FPS personally since I don't need more.

From looking up lines and screen glitches, this often means the GPU is faulty, which you no doubt guessed. I've seen overheating as a possibility, but the temperature looked alright to me. Memory can also be an issue, but the rest of the computer's activity looks the same as mine usually is.

I looked up the error and one person fixed it like this a few years ago (with a 3080):
"[set] gpu to stock frequency and that fixed my DirectX errors altogether. Some graphics cards come factory overclocked as well depending on the model, so you should try underclocking if your gpu happens to be overclocked. (-100mhz or -200mhz from stock)"

Another person had it caused by their memory being overclocked and another person had it caused by their Windows Time being out of sync (this can happen particularly if your CMOS battery is dying, which normally takes around 10 years at least).
