YO WHAT THE FUCK, I GOT IT FIXED. I did read that this didn't work for some, but I tried it anyways + I don't have a clue about pc's, so I can't really answer tech questions.
First of all, cleaned my PC. Swapped mainboard battery, RESETTED ALL SETTINGS IN THE MAINBOARD UEFI, uninstalled my gpu drivers and tried to install it again...but this time it didn't let me, the device manager gave an error under the gpu (Error 19, something about the registry) Then I fresh installed Windows (Delete everything and don't keep a single file on the PC)
Pc went on, everything looked like garbage like always, installed drivers - BOOM. Now it's crisp and fine.
This is exactly what I have done, maybe works for someone. This anti aliasing thing is cancerous as fuck.
