I use the same output as Brasseur (Ive never saw the need for PS output). I like using tiff because of the image quality. Bitmaps dont look very nice IMO. As far as speed goes, they're the same for me also.....if not slower because of the update. Anyway I'd Rand them as follows BMP Tiff PSD Just to add something - If you create a image, you can't rush it's render. Be patient. Expect some to be slow, especially when rendering to Disk for print. -Matt who just finished a 15H render
