I dont know if this will work with everyone but this is what I did to fix the MP/SP crashing:
Go to options:
Click optical Settings.
Then you change the graphics to low or high (If needed)
After turn off sync
then accept then your done.
It might crash but it takes a while now. I go through millions of maps without crashing. Hope this helped, happy new years.
this seems interesting,i have the problem and would very much like u to be correct! BUT, could you please clarify the isntructions? i don't understand! thankyou!
