..i just remembered, that there was a program called s-spline some years ago..found it again and now it's called PhotoZoom pro2....
Don't know if it's any help here, but take a look at the pictures...
First picture shows how 2kX2k dds looks, second picture is scaled up to 4kX4k with photoshop, using bicubic-smoother algorithm....and the last one is scaled up to 4kX4k with photozoom using s-spline xl algorithm....
-1-
-2- (this is from bmp-image, but there's no difference to .dds)
-3-
...next i'm gonna try how does it look in the game..:hmm:
