wabe, when i first heard of procedural terrains in vue i was super-excited. i'm not so excited now though i'm running a machine with a dual core 64bit athlon 3800+, the sexy nvidia geforce 7800GT and a gig of ram and procedural terrains STILL cause my machine a great deal of grief. i prefer working with an inferior, normal terrain and be able to move it around without it going all glitchy and stuff :p
