Problem is it isn't just 46 other people.
There are other servers running the same map, people are playing. Heck, another forum I'm on has probably 20 people discussing the beta, the only issues that have been mentioned are poor optimization and the server browser. So I'd safely say "the majority" are not CTDing every time a map comes up, seeing how I've seen more unique users nod in a positive manner than mention CTDing.
Until now I can personnaly report the crash problem to concern 3 out of 4 players.
But that could be because no crash guys might be playing more and have nothing to say about this since they don't crash.
