DR progressive mode Best setup for preview

[fraggle]

Hello,
What is the best vray bundle size/Min shading rate for a DR progressive rendering?
I tried a lot of different value (128/1 - 600/100 - 128/100 - 128/32 - 600/1...) but even when some value keep the host CPU at 100% instead of the dancing 0-44% obtain with the default value, at the end the faster (128/32 is only 1s faster than any other result!
Thanks

I think it would be best to try that again with the new SP, we've done some improvements in that regard. If you want, I can get you a preview build to try out if you email me to vlado@chaosgroup.com

Best regards,
