I know this is an old post, don't want to start a new thread, but after reading over this I get that you need to view the image at 100% to get the same quality however once you zoom out from that you are going to lose the quality again. Is there anyway to fix it so that when you have to pass your work on to say a client / put the image on your profile / website that is it viewed as you do when you look at the frame buffer?
There are not any gamma issues on the render but only the sharpness and loss of quality
