Can anyone even get off the home screen without crashing, game loads very slowly, get past the screen about not standing on the tracks and then that will be your lot.
I've used XBOX cloud gaming a fair bit, including with TSW6 and earlier, and it's worked well for me - useful service. Agree with owenroser19 that it sounds like a network issue - if you have a slow connection then there's unfortunately little that DTG or MS can do about that.
