The game has an interesting feel (More human like) Than the usual first person shooter.. Its as if your movement is weighted where as the usual first person shooter everything is instant and completely based on mouse speed settings.. Like instant 180 snaps.
The controls of this game are more complex for sure but once you get used to it it feels good. I love holding alt and looking over my shoulder while running. It's more realistic that I can look behind me while continuing in a certain direction.
Now I did notice when I manually set everything in video options to their highest.. 16x this and that.. There was a lag in motion that was not part of the game.. I tweaked a few down and it runs perfect now.
Have you tried on your new system Ron?
