Display Issues Since Wotlk

https://ift.tt/9ebJsrW buddy has searched the internet far and wide to fix his stuttering issue and has had no luck.Specs-RTX 3070Ryzen 590032gb of RamHe sent his card back and got a new one but it didn't fix the issue. The linked video is an example of the issue with no addons on. The computer was just reformatted to hopefully fix the issue but as shown, it still persists. He has tried new and old Graphics/ chipset drivers. No discord, Nvidia or Windows overlays are enabled. He has tried V-sync on and off and it's still the same.Does anyone have an idea what this could be? I am out of suggestions for him to try. The stuttering is only experienced in 25 man Ulduar and Dalaran. There are a lot of complaints on the forums about the same issue but there are no posted fixes to date.
