I was able to get rid of much of the stuttering by unchecking the option “Lock cursor to window” (since I only have one monitor).
Hope this helps someone!
Also, if you haven’t tried with all addons off before posting: it’s very possible an addon is causing your issue. That being said, it’s equally possible addons are NOT causing the issue but you need to do your due diligence to make sure its not addons.
I know that hitting “disable all addons” is a pain because you have to manually go back through the list to re-enable them. There is a quick way around this if you go to:
C:\Program Files (x86)\World of Warcraft\_retail_\WTF\Account\%accountname%\%realm%\%playernmame%\addons.txt
This has a list of what’s disabled and not. Before you disable all the addons, you can make a copy of this file to desktop and copy it back when you want to turn everything back on.
