Having trouble with Graphics

I’m new to playing modded servers every time I start to play it’s okay in parts but then the graphics start to just become very blocky. The buildings and roads vanish. I’ve tried turning my settings down but doesn’t seem to be fixing the problem. Not sure if it’s just the graphics card I have isn’t up to scratch (GTX 1660s)? or it’s something else? Any ideas on what else I can do to fix it, cos it’s unplayable at the moment? Appreciate any help.

You can put the process “Fivem_GTAProcess” into high. That helped a lot hope so for you too.
