Well I have had more than myself complain about this on Gossip so here goes.
Since 0.5.2 - 0.5.3 the graphic problems have gone down hill and I think a put back to 0.5.2 will have to be done. Some players have found it almost as bad as 0.5
The Problem - The problem is finding no texture on e.g walls, buildings, paths, grass, rocks, dirt, etc and only having black. With me I am finding areas in black for example: Ojaveda the two sides where most of the buildings are the ground is black the main road leading up to the central dsar is very dark but I can just see the road texture. Also most of us have found that loading Mobs takes time, and me personally are finding the arena a very lagging place to be.
