Not really, depends how it is done. Try to resize something in photoshop, it will not be pixelated now it is kinda impossible to do anything for smaller resolutions because it is really bad looking. Is is any way to blur it when it is resized or do some kind of AA?
Complaining about GPU texture filtering not giving you the same high quality effect of Photoshop texture resizing is like complaining about an $80 bicycle that can't reach the same speed as a Ferrari.The two methods have nothing to do with each other.
