I am playing Rayman 2 on 1920x1080 and I'm noticing some framerate drops in quite a few parts of the game (in specific areas and in most battles). Not to unplayable levels, but still very much noticeable considering how smooth it was at first.

Is this normal? I tried to lower the resolution using GXSetup and see if that helped, but doing so makes the game crash as soon as I open it.

And one more thing. I noticed the "draw distance" for the lums is quite inferior when compared to the DC and PS1 versions. Is there any way around that?
