laggy? slow load? render crash? try this.

[the benevolent adversary]

so I kept crashing with basically the same render (blah something render) problem after searching I found what works for me (the other solution seems to be installing old drivers for your vid card ...); turn off antialiasing and vsynch (I don't think this one is necessary but I did it) in options!
after doing this my game runs about 4 times faster with smoother controls and loads savegames in about 1 second. frankly I couldn't believe how much better my performance was after doing this.
