Well the issue with the PC version was that for some reason it kept trying to use people's integrated graphics cards as opposed to their GPUs. That appears to have been fixed, but honestly at this point this is getting embarrassing for TT. A game like this shouldn't have worse performance than a game like Titanfall or Halo 5. I think TT has given up trying to optimize their games and are instead relying on their content to help people forget about their technical shortcomings.
