I see only number getting higher from 0 to 20
look over preferences tab , but without success
and one more question please , do you plan to implement GPU acceleration ?
I know you have your own CPU renderfarm that can't stay without work , but anyway ...
there is a lacking of performance a little bit .
You cannot adjust the number of iterations at this time. It has a fixed maximum so that it does not "calculate forever". We may allow adjustment in the future.
A GPU version of the RTP is a possibility in the future. GPU acceleration for *primary* rendering is not likely to happen soon, however.
