Unless all the objects and players are loaded, the server is designed to give you that "black screen". People will low ping will rarely notice this because they load everything almost instantly. Although I would also like this effect to be removed because I don't see what is the problem in seeing the objects being loaded infront of us. Incase you want to partially avoid black screen, when you enter am interior, press tab, the background will no longer be blacked out and you will be able to see all the objects being loaded.
