DECENDS, I play COD BO3 and TF all the time. I think you're confusing graphic engine with gaming engine (I run both games on a GTX 980M). Set both games to run at 60 FPS (just for testing), you will notice that TF feels more nimble in movement, shooting, and definitely when jumping/wall running. For a twitch game, I would think COD would be better considering COD series have been around for a long time. After playing COD BO3, I seem to be so much better at TF. After playing TF, I feel clunky, like I'm moving at 90% of what I expect in COD BO3. I've had several of my COD fanboy friends reluctantly admit that TF runs quicker, but... yes, yes, yes, COD is better in many more ways.
Anyway, D@MN EA/Respawn for not letting PC gamers Beta Test!!!
