Lighting and shadows are much better. Game runs a bit smoother though is a bit more demanding on PC, but hardly anything no PC now-a-days can't handle by any means. Though there is one thing bugging me. ...I think Gordan has been given the ability to do pull ups. Like jumping at a ledge from a standing position you can jump toward an object which would normally be to high to jump on, but now I feel with the update you're basically doing a pull up now. . . . . went and loaded up Half Life 2 before the update and I can't. Ross Scott was right. Gordan can do a pull up.
