Minor Weird Graphical Bug

[NateTheSquid]

Whenever i join the server, the graphics looks more pixellated than they should be, and moving causes some Lag, i'm using the latest Beta build and switching to the Stable build has no effect, just 2 weeks ago everything was fine.
I also checked for viruses on my Pc but no results.

graphics look fine to me, idk though. Lag is probably your side, a bad internet connection or slow/busy computer. Try updating directx, that fixes a lot of problems with graphics
