I got this game last week, and I love the idea behind it. but i am not able to enjoy the gameplay. any game mode I try to play I get extreme lag, every 45 - 60 seconds the game will freeze for about a second. (Usually triggered by a graphical update such as a bricktron setting down planks or a stockpile of stone turning into bricks. "I think" ) This is still playable in my opinion, but once i've been playing for an hour or two, and i've built up an army of bricktrons and have built some structures, the lag gets worse . . . Much worse, where my game will freeze for up to 2 or 3 seconds, every 15 - 20 seconds. when a wave comes in invasion mode, starting around wave 15, the lag is so bad that i have to stop playing. my fps goes down to about 20 and it lags every 10 - 15 seconds for up to 5 seconds.
