Can't Set Max Framerate Anymore?

Hey there! I'll try to make this short and to the point. I always cap my frame rate at 72fps on a 144hz screen because, unfortunately, I'm really sensitive to the screen bobble affect that varying frame rates causes, at least on my PC, and it makes me want to throw up when it happens. This happens on every game, so I just cap every program's frame rate.

Anyway, I'm having this weird issue where FFXIV doesn't want to let me cap its frame rate anymore. I have it set to 1080p, 144hz, and I have "Limit frame rate to 72" checked, but it is running at 92 - 100 depending on the area. I even tried changing it to different frame rates, and none of them limit the fps. Frustrated, I went into the Nvidia control panel, and turned on Adaptive Vsync Half-Refresh Rate, and I was shocked to see that that didn't work either! FFXIV just keeps on running at the highest frame rate it can.

I was able to fix it for a limited amount of time by reinstalling my video drivers, which are the latest ones. I played the game for a few hours, and logged off and on at one point, seeing that it was still fixed. Then I didn't log on for about 20 hours, I didn't do anything to change my computer, not even turning it off. I just launched FFXIV again, and it's uncapped again with no solution.

If you guys can help out with any ideas at all, I'd be very appreciative! ^.^ Thanks!

You went through all the steps I would have.
Are you running it in fullscreen? If not, try it.

I am. I'm about to reformat my PC. It's like the game isn't respecting the changes I make in my driver settings, not even trying to force vsync.
