And this game is SUCKS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Wow. I haven't had any problems with my game. Not even with co-op. I'm using patch 1.05 US

I think there's definately some weird conflict in your system. I dare to say that over 98% of the Single Player players didnt have any of these problems.
You might want to send your dxdiag output to Ubi... I doubt they'll release a patch or be able to help you, though

so can anyone of you share your patch to me, it help me a lot too, i'm ****ing tired to play this game now.......

There is no patch for the problems you are reporting. Maybe you just have a bad copy of the game. Can you still exchange it?

how to exchange copy?

Take it to the store you bought it from with the receipt, and demand an exchange. They sold you a defective copy, so it's they're liable for anything that happens...or something. Unless you downloaded it illegally from online, in which case, you're sol.

if it's any consolation, I have exactly the same problems too...
