So I've finally decided to go to the forums for this, as I've been scouring for days & have found nothing on the issue.
I have a pretty high end laptop that runs FFXIV smoothly, always at 60fps & never had an issue before, save the occasional background program that'll stop my game until I close said program.
I recently installed GeForce Experience to run another game, as it wouldn't run without it. Ever since doing so, I've had nothing but framerate issues in FFXIV alone. It'll drop down below 10 frames & gameplay is unbearable in this state.
I uninstalled GeForce Experience & all that came with it, but this hasn't helped the issue. I uninstalled FFXIV itself & reinstalled it, but it's still suffering the same issue.
I've tried changing the settings of the game itself to run as low as possible, but still no difference. The only way I can get it to stop is by ALT + TAB out of the game, returning to it, only for the same thing to happen about 10 seconds later.
I've made sure that no background processes that could hinder the game are running & I don't have any viruses that could be breaking it down either.
I'm also running DirectX 12, so there shouldn't be an issue there.

Sorry if this seems kind of dumb to ask, but it's really messing up my experience. I'm not that well versed in the specs of computers, but I know how to give the information if required.

Thank you. c:
