PTGUI and Autopano Pro

I have Autopano Pro (APP) and which I am using to create a 360x180 view. APP has no problem doing the stitching but the final image is very soft and not smooth edges. Is there some parameters in the rendering that can improve the quality of the stiched image?
I tried PTGUI that had problem doing the sticht without doing a lot of manual work, but PTGUI produced very sharp stitched image. So the problem is not my photos, it has to do with the APP algorithm or configuration. Does any body else have problem with APP and know how to fix it?
Any suggestion will greatly be appreciated.
Also, what is a good ratio between the size of pano image and the size of the viewer? I am thinking that if the pano is too large, and the viewer is small, then the viewer has to do a lot of pixel interpolation. On the other hand, if the pano is small and the viewer is large, then the viewer will do pixel exrapolation (stretching) which will degrade the viewed panorama. There has to be some optimal ratio between the size of the stitched pano and the size of the viewer where you get optimum results. Any ideas?

On the rendering panel of Autopano Pro, you can select the interpolator to be used for remapping the images. Probably you have used bilinear by default. You should get sharper output with spline36, but you can try the other options too.
It is difficult to come up with optimum sizes of images because you also need to consider that the user normally has the option to zoom in and out. As a rough guide, you can take 5000x2500 as being adequate for a fullscreen display. But then - how big is the screen? Divide the panorama width by pi to get the optimum cubic tile size.
