The maker of this park pack released the rides by themselves along with the entire park so that you can ride them without lag. Pretty impressive..cant wait till he's done with MGM and Tommorowland.
I remember when the guy doing this first started out. It's such an excellent park when it doesn't lag. He's also got MGM coming, and RNR looks incredible.
A French Website has just released some really good custom scenery (castle, RNRC Guitar, etc.) Search the Exchange @ the RCT 3 forums (Atari). I think it is under custom scenery.
Man, I wished I have a better graphic card, rather than a intel integrated graphics. But still it looks good in some of my 3D games. I wish I have RCT3 with all of the expansions. But it may have some graphic degraditions for the game.
