Well I just got my copy of World in Conflict and it looks amazing but im having a huge problem. If im in single player or Multiplayer for more then 40mins my graphics start to artifact to hell and back and eventually hardlocks. Now iv tried running it in both DX10 and DX9 and both do the same thing, the weird thing is if i bump my graphics down to LOW or MEDIUM It doesnt happen....any ideas? Thanks
