I'm having problems using the PowerVR SDK for the Intel 2700g graphics chip (Dell X50V) - can someone confirm that fog calls are working properly - I am having major probs.
Thanks

This appears to be a bug with linear fog, and we're investigating the issue. As a workaround, you can change to exponential fog.

Tried that with no success; in my hands at least, all three fog modes (linear, exp, exp2) appear to be broken.

This issue was caused by a bug in the fixed-/floating-point abstraction macros we use in the PowerVR SDKs. It was fixed quite a long time ago now, the currently posted SDKs (http://www.pvrdev.com) being fine.
