I'm playing the game with Better Rayman 3 and i've been getting random lock up's . Not sure if it's Better Rayman 3 causing it or unless it's something else.

I think i might have figured out what was causing the lock ups

With Better Rayman 3 its either Hardware Vertex processing or Trilinear Mipmapping, I just un-ticked both of them and i've haven't had no trouble since.
