We are running A64 on Asus K8T800 Delux (in turbo mode), Gainward 256MB DDR AGP 8X, 1 GB DDR 400 (512 x 2), XP Pro, Maxtor 250GB HD x 2, Poser 5 SR 4.1... still, no problems. I doubt Daz would ship D|S for A64 until Intel comes out with their version. On an older Athlon XP, we noticed Poser 5 runs faster on 1GB compared to 512MB. When we increase the ram to 1.5GB (512MB x 3), the speed did not increase. In fact, it slowed down just a tad. In the test, P5 used as much as 99.5% of the physical RAM (using Norton system work utility) during very large renders. Of course XP base programs were also using the ram at that time. P5 did not crash even at the maximum render resolution. It's sad though... PC are way faster than they were back in the day. Infact, what we really have now is a ultra fast supercomputer. But add a dozen V3 figures in a scene and watch it crawl like a baby. And if you want to see time stand still, try that with D|S.
