The question is my friend, why do they need to patch this game?
I mean, we already payed, so... why care about us anymore? Their product is out, is badly optimised, but people are still buying it. It literally makes no sense from a business perspective to patch it and waste money on it. True, patching it would not be costly, but still, those dollars could buy a EA ceo a coffee and a bagle he wouldn't have otherwise.
My ranting aside, seriously, if this turns out to be cause by the DRM than I bet, once someone pirates the game, it will turn out that the pirate version will run a lot more smoothly than our payed versions. And really, that is simply the most annoying perspective, and "screw you" from EA to their customers ever...
