I have this, but once in a while the next map loads, it doesn't always happen.
It may be the non-original maps that crash for me, lakeside, goldrush, maybe others.
I had settings to Ultra with everything unticked, and tried with everything ticked, and happened both ways.
I didn't experience this with the last Beta Release, and thought maybe the server was kicking me for another player since this happened on full servers for me.
Maybe its something with 64 bit windows, and direct X.
I thought I got a Direct X 32bit error after one of the crashes but didn't save a screenie, so it may have said something else.
Ill change the presets down to see if that helps.
