Funnily, Ive read a lot of critics and other threads about this game and there are only very few people who actually have technical issues after 1.01 with ArmA 2. The vast majority who bought this game enjoy it very much.
Most people actually say that it is far less buggy and far more playable than ArmA 1 ever was until 1.12 and I agree 100% with them.
Your problems have another reason. Maybe ignorance, or a crappy computer or youre indeed only a simple troll.
I have given up on waiting for BIS to come back to their senses and do a real ArmA 2 successor.
