For some reason after about 15 minutes of playing I start to get some weird lag during songs. Originally it would be at 144hz/144hz (unlimited.) Its as if it's progressively dropping my frames to about 120 FPS on its own while it is at unlimited. I've checked the forums to see if anyone has had any similar problems, but no one seems to have it. My rig shouldn't be an issue.
Things I know/did:
-Drivers are updated
-There is no firewall or any anti-viruses running
-GPU/CPU temp are extremely cool.
-Disabled all overlays
-There are no background applications that would hinder performance (I've restarted and tried separate applications and i'm still lagging ex:discord, steam, launchers etc)
-I've also tried no applications
-Disabled chrome plugins
-Tried/deleted separate skins to see if something might be corrupted
-Played around with Fullscreen and windowed
-Tried Stable and Beta
-Tried Compatibility mode

Osu! is on a 450g SSD (with plenty of space left)
At this point I'm looking for suggestions as to what I should do before I uninstall and reinstall.
I'd like to believe I might be missing something and that it doesn't have to resort to me having a fresh game. Please let me know, I'm open to anything.
The only way I can have it stop lagging is to just exit osu and relaunch. This is extremely tedious.
