For those with a 32 Mb (or less) graphics cards, manipulating your component in Photo Renderer can be painfull !
We now use Alibre Design and Photo Renderer on a PC with a 256 Mb AGP graphics card and the difference is unbelievable.
You can virtually rotate, zoom and pan with performance that almost matches doing the same in Alibre Design (not quite but close). We plan to go to a 1 Gig graphics card on a PC with 4 Gig of RAM soon.
Essentially, make sure you have a good graphics card (lots of RAM) and a decent amount of RAM (> 1 Gig) in your PC, if you're going to use Photo Renderer for serious work.
Note: Photo Renderer still works on our 32 Mb graphics card machine, its just that you have to wait for the scene to update - kind of like waiting for the bath to drain
