Yeah the animations are good, but there should be more variations of running. Geralt does not slow down when he is climbing steep hills, so there should be another set of animations for running up a hill. And as I said before a smoother transition between different speeds like walking and sprinting would really add to the realism.Dude the running is awesome!!! Now it really gives the feeling that you're sprinting and not just jogging, I think that's a great improvement, but I agree it would be nice if you could run in almost inhuman speed for a small window of time. I wonder if you can flee from any enemy just by running away, or if some actually catch up to you.
REDs say that you can, but an interviewer who had hands on experience with the January build said that it is difficult to do so. It was a video interview, so don't ask me for a source. Trust your fellow WIitcher
