The biggest annoyance surrounding this game isn't the game it self, but its people's awulf usage of the term 'optimization'. The game has had minor optimization issues but it isn't completely broken.
The game and engine is just seriously pushing more effects than 99.99% of games have tried to do before, and if you've got a decent system, it looks spectacular. Simply put, modern graphics card can't run it at higher settings just simply because of what the engine is doing. And that is not an optimization issue. Its just doing a lot more than we are capable. In a way its future proofed, but more importantly, it is just flat out impressive what the game/engine does. The visual effects and output are fantastic. So please stop perpetuating this, 'unoptimized game' myth. It's exactly the opposite. It is the closest thing we have to Crysis this gen.
