There is a lot of help at RDNA Poser 6 forum...I have been learning a lot there in between my times I want to "give up"... I have noticed the MOST important thing is that your graphics card have the most up to date driver!!!' I also learned the odd thing of lowering the 'bucket' size to allow the render to work... I normally use 64...but taking it back to 32 or less...makes slower render but does allow for more figures in the scene. Beyond that, I do have an AMD 3 gig cpu and 1 1/2 of the right kind of ram for my 64 bit board... and Poser 6 is a happy camper. Now, when I close it, having been using my P5 runtime...then next time I open it takes a long time...BUT if I re-open the same day, it will load pretty fast then... even with P5 I keep trying to remind myself to have a TINY figure and pose library last opened, so when it comes back to open again, it does not have to "load" such a big bunch of files. Hope it works out for you, you didn't say what your hardware is? I know my P5 is a LOT steadier on a higher end machine. (and have been told that a 64 bit machine makes no difference for Poser because it is not written to take advantage of it...BUT the machine has a lot of power so works really well anyway.) I use a radeon graphics chipset too, not nvidia.
