Well first is first. Check your PC settings. If you have a gig of ram then you you should have 1.5 times that or 1536 for a page file. Right-click on My Computer and select properties. Click on advanced tab and then click on the settings button in the Performance section. Make sure Programs is selected in Processor Scheduling and Memory Usage. Check the paging file size and if it isn't around 1536 then click fthe change button and change it. As to a graphics card, it depends on how much you want to spend. I would recommend a card with 256MB of DDR2 or DDR3 memory. It'll cost north of 200 bucks though. As to P6, I don't have it yet but... You have shadow catcher now right? So, render your scene without any shadows first then do another render with shadows only. That should help. I'm sure much more knowledgable people here will give you more advice! E...
