Hi,

I'm trying to use local program parameters within an ARB_fragment_program. The first time I set the parameters, they are correctly used in the fragment program. But if I change the parameter again, the changes are not applied to the register in the fragment program. I can read the changed values using getProgramLocalParameter* though.

This is happening with an NVidia FX5600 / 44.03. On an ATI 9700, everything works correctly. Have I stumbled accross a driver issue, or did I miss a magic "update values" switch?

I have exactly the same problem. And I am quite sure it is a bug in Det 44.03. I have written to Nvidia support about this but got no reply. Maybe someone from Nvidia could confirm this?

Regards,
Mark

I hade the same problem; downgrading to the previous driver (43.xx) fixed the problem for me.

It's a driver bug. Already been discussed here:
