I have all 3 descents installed. D1 works great, D3 works great, but Descent 2 plays extremely fast, the ship bobs up and down 2-3 times faster than it should, lasers fire fast, bots move fast. Its unplayable. I cant find any settings for the gamespeed, does anyone else have this problem or know a fix? Im on a Win7 pc 64bit.

Good call, its playable now, and i got set up with the descent rangers for multiplayer.

Awesome! :) If you ever need any help with it, just ask here or on the Rebirth forums :)
