dude a mod just told you what to do.
-
Dont join a server with alot of resources.
If that dose not work move to step 2 -
or your internet may be too slow or the server itself is too slow. (Meaning: Cant join any fivem server)
If its still not working then you simply cant play fiveM until you have proper requirements to run fivem.
think about it this way…
you cant expect a mechanic to fix a car without a toolbox.
if you dont have the internet speed to play fivem then dont play.
sorry bud.
