Consistent FPS Drops based on Refresh Rate

[Resulon12]

I followed the instructions. Issue still persists.
I find it so strange that when i lock the game to 60 fps those stay consistent but when it goes higher the frames drop into the abyss.

Ok, i belive the issue has been found: Its not just a ffxiv-thing. Apparently the cooling of my cpu is broken causing my pc to get trottled as to not overheat which is creating performance issues in EVERY Game.
A Technician has been called to look into the hardware.

Thank you for your help!
