I stand corrected. My true meaning was that MS' claims of 120fps would only be some select last-gen games and their BC games.Maybe I am reading your comment wrong? because when you said "The only way MS is tooting their 120fps horn is because of their BC catalogue. #thereisnospoon" I simply picked Dirt because it had the option of running at 120FPS and was not a BC game.
But by all means, show me that performance delta. I'm certainly not too high on myself to admit it if I'm wrong.
