Hang while playing

It's me again.
While I am playing the eastern front maps for about 20-60 second,
it suddenly hang, and keep there...

Also, when my tank was shot by AT gun, the whole tank turn to black. :o

Why?  :'(

Custom vehicles have bugged scarring. You should go to graphic options and turn scarring off.

Which are your PC specs?
What settings do you use for CoH? (Ultra/High/Medium/Low)

Thanks, but i use the same setting with the original company of heroes. and i also turn on the scarring and there's on problem in the original company of heroes.

I'm sure you don't have such problem on CoH, the problem has to do with Custom vehicles and the former doesn't use those ;D.

Custom vehicles are any new vehicle implemented on a CoH mod.

Really?!
Thank alot !! ;D
