The instructions from the 3ds max thread are not sufficient for Poser. You need to patch the Poser binary and set the /LARGEADDRESSAWARE flag, otherwise Windows will not give out a single Byte more. I did not provide a "for dummies" tutorial on purpose. In certain cases, the /3GB flag could reduce overall performance or even cause a non-booting system. And I don't want anyone who doesn't know how to undo the changes run into such a situation.
