Yeah I heard there was a massive patch for the PC not long after it released because it was crashing people's systems and totally unplayable I personally don't really like what they've done with MK X, it's the only fighting game I've played (and I've played the majority of them) where I can't pull off simple combos because the timing is really weird. I also feel the character animations and movements are too clunky and certain characters are just more easier to play with (which is why most pick Scorpion and Sub Zero) I hope they fix the net code to a certain extent though
