I'm guessing OptiFine uses optimizations that don't scale well across platforms, which is why it's not implemented in the main code (yet).

Well thank you for your incredible kindness by insulting me instead of staying on topic.
All I was saying is that sure, minecraft can improve and that's what this bugtracker is for, but exclaiming it's all shit, even if you can point to things like optifine that fix it, it's not a bug, it's a complaint, and should therefore be discussed on the forums.
If you've encountered specific ingame error messages which you believe are caused by bugs, then that's exactly what this bugtracker is for, and you're more than welcome to share what you've found.
But suit yourself, I will take no more time of your precious high intellect. /sigh

No offense, but this is a bug tracker. Bug trackers require very specific information on a single issue inside the game. Saying "The game's shit written and doesn't work on low end PCs" is more of a forum thing than something for a bug tracker.
