Hello everybody

My question has probably been addressed before but I can't find the answer. So please excuse me for asking again!

I run Poser 6 on a 3.6 GHz P4 with hyperthreading, 2 GB DRAM, and Windows XP Home with SP3.

I never had any problems until the day I wanted to render a scene with 2 Victoria 3 incl. cloths. The scene wouldn't render until I reduced max. texture size to 1536. I checked with the task manager and made a couple of puzzling observations (at least puzzling to me, I'm not a technical guy):

Memory usage for the Poser 6 process was approx. 900 MB. Total memory usage of all processes running was about 1.2 GB. Why Poser 6 complains about not having enough memeory when there are approx. 800 MB free RAM? I thought Win XP can assign max. 2 GB per task !

Processor usage during rendering (at low texture size) was 50% in average. Why the hell does't Poser use all processor capacity?

I'm curious if there is a solution to this which doesn't involve buying a new computer or upgrading the operating system to XP Professional or Vista. I would consider to upgrade DRAM to 3 GB if that helps but as long the 2 GB I have are not used that doesn't seem to make much sense.

Any advise highly appreciated!

Regards,
Christoph
