Sgx530 z buffer precision....

Hi All,

I’ve a problem with my shadow mapping shader on sgx530 chips ( working fine on 535,540 ). The problem seems to be the zbuffer precision  compared to the 535,540.

Is the 530 quite different to the 535,540? I’ve attached a image that shows the problem, on the 535/540 it’s clean but here on the 530 its a bit of a mess…

Cheers



Could you attach a ‘correct’ image that matches the ‘problem’ image?
