I can't speak for Poser importation, but I can tell you my experience with Vue 5 Infinite has been satisfactory. Overall, at this stage of patching, I'll give it a B-. There have been two patches for Infinite since I purchased the product a little over a month ago, and the software's memory management is still an on-going issue. For the Mac users, the issue is less eveident with the newer build, but the PC users are still complaining. If you visit the Vue forums at e-on, you'll see this is the case, but unfortunately, you can't view the forums unless you've purchased and registered an e-on product. But trust me, the complaints remain. I bring my PC to its knees with a polygon count approaching 1.5 to 2 billion, but can still manage a render. Above that, I'll crash 50% of the time, below that, say 500 million, software performance is reduced dramatically. With that said, I still enjoy using the software, I just have to be aware of what's going on in the worlds I create as well as tweak the software a tad. Using billboards helps tremendously (learned that here). If I keep an eye out on resources, I rarely crash. I'm not aware of a "major bug fix patch" but I do know e-on is well aware of the memory/performance issues of Infinite on the Windows platform and would guess there will be several more builds before most of the issues are addressed, just like Vue 4. Vue 5 Infinite is their flagship product, no doubt it's high-priority. E-on's customer support is top notch, IMHO. If I might add, while $200 is quite a bit more for the Infinite product, it's well worth the extra expense. Somewhere on the e-on web site is a comparison page between the products. Compare between Esprit, Pro and Infinite and you'll see what I mean. Bottom Line: I recommend Vue 5 Infinite to anyone. It's a fantastic product and well worth the investment. BTW, my recommendation would be 2 gigs of fast RAM, no matter what e-on says. The more the merrier with Infinite.
