I recently upgraded to Win XP Pro from Windows ME. I Installed Poser 5 and the program runs exteamly lag and frequently crashes. I am all caught up on the Poser Service Packs and on the Windows XP updates. Does anyone else have this problem or know how to fix it?

is use xp home without any problems.dont think it slower on xp pro.

On the contrary. Poser should run better under WinXP than under ME. I also went from ME to XP ( before I got P5 though) and everything is fine. But XP loves memory and so does Poser 5. How much RAM do you have?

I run Poser5 with XP Home, no probs (other than the bugs people know about). Turn off the XP fancy eye candy. I run Home in the classic mode (looks like win98). This helped a LOT, I don't know why just did.

I'm running XP pro and haven't been having Poser crashes.

Oh yeah... Turning off the eye candy makes a difference. I forgot to mention it becourse it was one of the first things I did when I got my XP :o) That Lego look didn't suit me.

...make a clean installation, is preferible than upgrading from ME to XP... Ascii

It would help to have a comprehensive inventory of your hardware and software to give a really good evaluation. Chances are that you have an older computer which might be "borderline" for handling Windows XP and Poser 5. But then again, maybe not.

Try increasing your virtual memory.

It is a clean installation of XP Pro and of Poser 5. I'm using a 2ghz P4 with 256Mb's of ram.

You have a relatively new computer. I'm surprised since you were previously running Windows ME. In fact, your computer is more powerful than mine. You are a bit light on the memory. You might want to increase the memory to at least 512MB. I have 512MB, and Poser bogs down on me sometimes. I have no crashes at all.

That configuration is exactely like my own, 2Gb P4 ans 256 Mb Ram. No problems. Only difference is that I am using XP Home and I doubt it should be any problem :o) Strange. I've never had P5 crashing on my system. But I must admit that I still mostly use PPP since it IS faster all in all.

...at my worksite, AMD 1.2Gb, 256Mb RAM, Gforce 4 MX 440, 40 Gb HDD(with only 3 Gb of virtual memory),Win XP pro,(the latest drivers and patches for everything), and no problems at all with both Posers(which own the company that I work for)... Ascii

I've got XP pro, (no eye candy) fully patched atop a 2Ghz P4, 1Gb of PC2700 DDR RAM and a Radeon 9700pro, and I have to say that since SR 2.1 (available at curious labs site) P5 has been a lot more stable, it's still terminally slow compared to Poser 4.03 running the same scene, but it doesn't crash nearly as much as it did. However it extrememly dangerous to introduce P4 light sets, as that tends to kill P5, and several people have also reported problems with such things as drivers for graphics tablets, printers and CD-writers. you'd be advised to rid your system of any of the above and see if that helps. It is slower than P4 in all respects, but once patched it should be fairly stable, in the time I've used it since the patch it hasn't crashed once, but then you can the number of times I've used it one one hand. YMMV later jb
