Although Turok uses the the dedicated engine, the PowerVR doesn't produce a very nice picture. Compared to the reference picture the sky and clouds aren't transparent at all, looks as if the PowerVR produces some really heavy weather. The waterfall isn't fultered very well and there seems to be a Z-information problem with the rock on the left. All in all is Turok playable, doesn't look too bad, but most other cards are offering a better image quality under Turok.

Reference Picture

The above is the ideal picture, produced by a 3Dfx Voodoo card under Glide engine.
