well I was facing this problem before but I have fixed it by trying this steps :1- Don't use GTA SA Random versions and use the orginal one which is +3GB2- Make sure to add your game to Nvidia Mange 3D Settings and set the settings to default and check before start changing the settings > Show content3- Also try to higher the Far Distance in the game ( And the Bases are not effected by it ) > Show content* Also its weird RTX30s have issue loading this game , So try to update your driver and test it using MSI Kombustor.
Come to settings and use those settings:Good Textures: 1000Detail Shader: 1000Car Reflection Shader: 1000Those worked for me when I downloaded the game for the first time after formatting my pc, I recommend you to try those.
Your streaming memory is very weak probably, try to max the bar which is located at MTA Settings > Advanced. If this doesn't work you possibly play from a very low spec PC, I used to face similar problems while I was playing from my old laptop.
Where does this happen?
Any errors you get in F8 console or chatbox you get when you log in?
this is from the server, they made it to avoid Non-GTASA builds to cause lag to the server and player we all have it as you see here: Show contentSAB Tower ( GTA Building )SAPD Base ( Not GTA Building )
