Now that mainstream PCs are moving to 64 bit OS, mostly win7 (but there are xp 64 and vista64) and soon win8,
and RAM is very often more than 3GB,
highly suggest TFP be re-configured to run in 64 bit mode and take advantage of multi-processors multi-threaded, as well as using much more than 32 bit limit of about 3GB...say up to OS max. or at least 16GB.
Such a product would appeal to more users with opportunity for better models and faster renders (both basic and advanced).
