So not sure what is correct. It works just fine, or at least it did on older platforms. So unless they broke it recently we should be good. Regarding fp16 vs. colorkey, not sure what the deal really is. I should probably test it across the board now that we have fp16 for all gen4+.

Will try to get some clarification from hardware folks as well. >Regarding fp16 vs. colorkey, not sure what the deal really is. >I should probably test it across the board now that we have >fp16 for all gen4+. That would be great and will confirm the behaviour. Regards, Uma Shankar >-- >Ville Syrjälä >Intel
