On my Pentium 3, 800MHz, 256MB RAM desktop--slow slow slow and freezes up most of the time, several prompts to send information to Microsoft. On my laptop (not upgradeable) Pentium 3 1GHz, 512 MB RAM, its a little faster, but there are occasional freezes. Both are on Win XP Home. I have noticed that when it freezes up, and I do a CTRL ALT DEL, wait a couple of seconds, and then NOT end task, the program unfreezes and returns to normal (better than yelling at it). On my slow ass systems, I'm going back to Poser 4 even though P5 has a lot of nice features. I just can't run it until I get a faster machine. I would suggest a Pentium 4 for this program and it should have been a minimum requirement otherwise I would have held off purchasing this program.

Poser 2, 3, 4, 5, 6, 7, 8, 9, 10, Pro 2014, 11, 11 Pro
