Which antivirus/firewall software are you using?
BitDefender Free
Did you try to disable/uninstall your Anti-virus?
No

I’ve tried to Lower Graphic Settings, Delete Cache, Set FiveM priority to high, enable/ disable vsync ingame, try to equal both cpu and gpu usage since in low my cpu is 100% usage and my gpu 10% and medium/high they are both 80/90%, Clear temporary files (%temp%, temp, prefetch)
After so many tries, only vsync seemed to help a bit but now my fps are crazy, sometimes i go to 20fps.
What i think can be is my HDD that is old and slow(ST1000LM024 HN-M101MBB)even tho crystal disk says he is healthy, that or my Internet since in fortnite that same stuff hapened, if i have limited the frames to 60 it would be better, but with unlimited fps textures also missing.
