Whats the concensus out there regarding the amount of additional ram for decreasing rendering time? I have 512mb now which is fine for "painter" but have just acquired my first Bryce 5.I do my post work in painter and adobe photo shop for cloning and adding 2d images which work faster than importing them to Bryce.I was thinking of adding another 512mb if even it would make a small diff. (Emachine,2.1 gig processor 512mb of ddr). Thanx Dave
