Relaunching XIV after closing applies a forced 60 fps cap

Date & Time: Starting in 5.0
Frequency: Every time I close the game and reopen it.

I have a 165hz monitor and use the unlimited frame rate setting, but since 5.0 launched, closing XIV and reopening it after about half an hour makes it launch with some kind of forced vsync of 60 fps. However although the system config menu shows 59 fps, what actually appears on screen seems to be more in the realm of 5 to 10 fps as the game moves like a slideshow. Changing fps cap settings and borderless/fullscreen options does nothing. Switching the frame rate limit from "None" to any of the other 165/82/41 refresh rate options makes the game unplayable as it runs at about 1 fps instead and menus are impossible to navigate at that point.

I've tried everything to fix the problem but nothing works except restarting my entire computer. My monitor is confirmed to be at 165hz and nvidia control panel is also set to 165hz.

Will try to add video evidence at a future time.

Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

It looks like you have a few monitors, does the same thing happen if you use one of the other, lower-refresh rate monitors? Does the same thing happen if you disconnect the other two?

You mentioned that you have already tried some troubleshooting. What exactly have you tried so far?

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
