i'm using 1.90g, and it seems quite fun
the state transitions are unusable though, and for some odd reason, it says that my Geforce 3 has a problem wiht its drivers that will significantly slow down transition effects.... i'm using detonators (28.32). if anyone has the new ones, tell me if it still says the same thing
other than that, this program rocks! almost no other slowdowns at all.. quite fun
