I was fooling with trying to get an 8x10 photo from Vue and did some renders at 3,000 x  2,400 pixels at 300dpi and turned off anti aliasing, now at the screen resolution I use 1200 x 800 the picture is grainy and larger than the screem, but if i reduce the image size it smooths out the image nicely while retaining detail, in my opinion a better result that  if I had rendereded it at 1200 x 800 with anti aliasing.  What are the downsides of doing this? and if I got an 8 x 10 print at say Walgreens would it look like a photo, especially grainwise,  taken at that resolution from my camera which takes about the same size image?
