I did not test it, but I believe this is the the setting you need to change for the ice physics:
Ground map needs a
lot of work.
Cliff texture is low resolution. I suggest at least 2048x2048 (if it is a square texture).
Use realistic colors, here is an example from a ground map that I made a while ago of changing B40 into a forest environment.

I know that the quality is bad, but I do not have the file on this computer, so I just took this jpeg from another thread that I posted in a few months ago.
