We have a mystery on our server. We were 3 man inside, one of us having a new installation of GTA 5. But him with the newinstall did not see certain things the rest of us could, some oil barrels, traffic cones and certain chairs.
Is it so, that you have to have a certain (higher) ‘rank’ in GTA, in order to see everything ??
Okay, he can try in Story Mode directly and see what he can see as step one, but ??
Øhhh 
That happens if you have low graphics settings. Increase ‘Distance Scaling’ above 20% to see these objects.
Okayy and thanks 
…
I will tell him about this…
Now the good man put everything at ‘full throttle’ and it has not helped, still there are things that can not be seen 
. So he decided to reinstall the complete GTA from CDs and not from the download as before. Can not find at other solutions, hope it helps 
.
