ested with several PCs, all of them with fresh Win8 64bit and fresh Win7 64bit installations.

I have several AMD graphic cards (7970 GHz, 7950 OC, 7870 XT, 6950, 6870),

further description was tested on all of them. Each time same issue.

With Windows buildin drivers from Microsoft there are NO issues.

With AMD Catalyst drivers 13.1, 13.2b7, 13.3b3 allways transparency issues appear.

How does it looks like:

In Everquest 2 character models and NPC models seems to be partialy transparent.
E.g Torso is ok, legs are transparent
or playermodell is ok, but mount is transparent,
or Head is ok, but Torso is transparent.

You can see the texture of the modell, but you also see the background.
Texture of modell is somewhat rasterized/pixelated like an old diffusion printout.
