    PVRTC compression artifacts(?)

    Sprites, PVRTC and artifacts on the edges

    What's wrong with the "Bumped Specular" shader on ipad 2?

    I'm a bit confused by that statement. PVR is a wrapper (e.g. like DDS) that can support numerous different formats including RGBA8888, RGB565, and...

    What's wrong with the "Bumped Specular" shader on ipad 2?

    Just to add to that, if you can afford to compute the Z in the shader, then put X and Y into R and G (as those have the greatest accuracy in...

    I don't know much about Unity, but the only thing that I can think of is that maybe the blend mode isnt taking the alpha into account.

    Pixelation problem of texture inside Unity

    It's a bit hard to tell from the pictures you posted but, to me, that looks like it's been (badly) low-pass filtered. Has it been downscaled at...

    Is the quality of PVRTC something that PowerVR can improve?

    Sorry, but what sort of image data are you using where 4bpp DXTC (i.e. DXT1) is better than 4bpp PVRTC? Certainly, if all of your texture data...
