What's the best method for PVRTC Compression?

[highpockets]

On most of my textures, the default RGBA PVRTC 4 bits works good enough when the compression quality is set to “Normal”, but sometimes it gives way below par results.

Is there a huge performance difference in-between “Normal” and “Best” compression quality?

“Best” gives me a way better result.

If I have this texture as a texture atlas, which pretty much takes care of all of my geometry, will that have a positive, negative or neutral affect on compression performance? If it is a positive affect, then maybe I can get away with increasing the compression quality…??

Any thoughts?

Thanks in advance.

In my experience, the difference is only the actual processing time between the two textures (so it should only affect you in the editor). By using “best” compression, you’re going to spend a lot longer whenever you have to reimport the texture, where it happens relatively quickly when its in normal mode.
