GI flicker wont go away.. tried everything

Hi everyone,

So in my scene, there are small clustered, white dancing flickering artifacts from certain angles on my model as it rotates.

I'm aware this is a GI issue, but i've tried everything to no avail. Different large, small and medium irradiance caches, small medium large sampling, turning up the raytraced hard shadow samples.

But nothing seems to beat it.

Any ideas clever people of Creative Cow?

Thanks!

Dan.
