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

One thing to help with the combos is turing off release control in the button setting when choosing a character, it really makes a difference when pulling off combos

Already did that, was never sure why it was on by default anyway. I noticed that I was having trouble with one of Kung Laos combos which was 1,1 (212) 4 or square, square (triangle, square, triangle), circle That should be an easy combo to perform. But the problem is I could pull it off but the timing was a joke, it has to be so precise that you'd never pull it off online, even offline it was very inconsistent The same move was in MK9 and I had no problem pulling it off. Not all the moves are hard to execute on X but there's a clunky-ness to it which puts me off
