The UI lag is still here and making the game feel very slugish and eating up a ton of cpu power (the freaking main menu is using 15% of my quadcore. Thats 1 core 60% stressed which is completely ridiculous). This is one of the main things that make the game less fun to play and also impossible to play on less powerfull hardware because its lowers fps alot on top of making the game feel slugish.
Indeed, pretty frustrating, but performance increases have been promised. Getting the function in comes first, cleaning it all up comes later down the road. They've said we should be seeing performance increases in the next few patches.
