Hi, I've tried Open FX (also have Rhino) and for the amount of time I had it up and running it looked really promising. However it crashed a lot. Could have been the vid card - mx2, 32 mg - but I suspect the program has a few bugs too. I really do wish it would operate well as it really is interesting and anytime something good like this comes along for free, the price of others comes down a little. Actually I dont mind paying for really good software like Rhino, but I can't afford the really pricey stuff so I have to wait for the "comsumer" oriented wares to just get better. Hope others are having better luck with Open FX.
