I have read a few posts indicating that Poser 5 is not written as a multi-threaded application and therefore cannot take advantage of dual processors. Does this also mean that the Firefly render engine will not benefit from a second processor? I am considering upgrading from a 1.0 GHZ pentium with 512 Kb of ram to a dual Athalon CPU system and want to know if dual processors would be any better than just upgrading to a faster single processor? Thanks in advance, rDogg
