Did 3 hours on it post midnight last night so I could play with my brother (he's in Chicago at the minute).
He kept having it crash on launch (error 25) and spent about an hour trying various fixing before remembering he'd put it his laptop into low power mode, switched that back to high and it loaded first time.
Once in game I had 3 "GPU driver" crashes over a couple of matches. Tried turning my Afterburner overclock down from +200mhz to +180mhz and it seemed fine after that.
The downed screen UI is where it should have been from the start now. You can see how far medics are away, if people have tagged you for a revive etc. Had fun on breakthrough until we just ended up defending rooftops and it was the usual boring end to the match.
Tried jumping into BF1942 conquest and the server felt empty which was weird and it finished about a minute after we joined.
