I just timed my poser 4 pro pack start up. From the moment of double clicking the desktop icon to where it's ready to start; 54 Seconds. Athlon 2100+ %12MB Ram, running Poser of a 14Gb partition with 5.7Gb Free space on htere. It does start up a lot quicker if I start it up a second time without restarting my PC in between. (After doing some caharacter creation I like to restart because all the textures loaded into the material files.)
