Ok, I'm on a 2Ghz Intel P4 w/512MB RAM, 64MB nvidia GeForce 440MX, 80GB 7200rpm hard drive for the OS and all applications, and several other various 10GB and 20GB drives to render animation to, mostly 5400rpm drives. This is not only my Poser PC, but is also used in my recording studio - and there are a ton of applications and audio files. Mitsubishi Diamond Point NX85 18.1" flat-panel LCD. Also a few external USB drives for storage, and an iMation LS120 hi-capacity USB floppy. Audio cards include M-Audio's Delta 66 and Omni Studio, and various versions of SoundBlaster. (I tend to swap them a bit to test how my stuff sounds on various cards) CD's are a Teac 8x internal CD-RW, and a Yamaha 4416 External SCSI cd-rw. OS is Windows 2000 Professional with SP3, IE 5.50.4807.2300, w/128-bit encryption installed. Outlook 2000. I also run Zone Alarm, NAV, a dozen other things. I've even had Poser rendering in the background while recording a guitar track in Acid Pro 4. Don't ask how, I think I lucked out, but it didn't even hiccup. I defrag my hard drives every other day, and make sure to clean all temp files - between audio work, Poser, and web surfing it ends up being about 200-300 MB's after a couple of hours. I also reboot several times within a 5-6 hour work period. And if Poser starts running a little slow, I close it and reopen to give it a boost - lets it clear out all its temp files I guess. But yeah, I've had no issues. I really didn't have any with Poser straight out of the box back in September, either, other than the Materials Room. (I can't even remember that particular bug now). I usually work with Vicky 2 and Mike 2, mostly not loading more than 7-8 characters at a time. (FYI, I've also had Poser 5 run very good on my AMD K6-2 500Mhz with only 256MB RAM, and it did just fine under Win2k/SP3. Rendering wasn't fast, but I'm probably just spoiled now I think!) Hope this helps in your quest for info... -silver
