when switching to raytraced and whenever moving around in raytraced viewport rhino wip used to initially turn on rendered mode for better responsiveness and blended over to raytraced after a few seconds. that was a really smart solution, i think. but it is gone?! no more start from rendered mode and blend over any more, immediately raytraced now. much more laggy now, miss the responsiveness.
BUG?
It is not gone, it just isnât default behaviour. In advanced options set UseFastDraw to true.
Thanks, thatâs it.
Since this is solved with your answer I wanted to âcheck-markâ this, cause Iâve seen it in other posts. Canât find this option 
No, I got that of course. 
I mean here in the forum I saw those little check-marks for answers that solve a problem.
That checkbox should be on that bottom row with the heart, link, and 3 dots.
Ow, that checkbox⌠^.^
yes, THAT checkbox. I love checking boxes - so where is it?
As the @wim says:
Maybe try the dots?
the dots just reveal the options:
heart, share, flag and bookmark, nothing else 
Sorry, then I donât know. I think that is then @brian or @stevebaer territory⌠(the checkbox for solution).
The solution checkbox is a setting that has to be enabled per-category, and wasnât enabled in Serengeti>Rendering WIP. I just enabled it, so now you can mark the solution!

Cool!
AWESOME!
so only one post can be checked as solution. if I check another one as well, the one I checked before gets unchecked. OK, guess that makes sense.
Btw, in the next BETA build youâll get some nicer ogl drawing as well - with SSAO, while tumbling and using UseFastDraw. Also, if not using UseFastDraw there will be degradation, just a bit different from UseFastDraw (and something that other realtime render engines directly benefit from without having to do anything special).
BUT I WANT TRUE-AO, no just kidding of course, thatâs great news.
read it a few times now, but still donât quite know what it means.
For Raytraced degradation means going from highest quality to lower to keep a sense of responsiveness. When you use UseFastDraw the openGL version will be drawn first - this is a âdegradedâ, fewer visual features, from Raytraced. The blending in of the Raytraced version tries to make the transition from OpenGL to Raytraced as smooth as possible. But the tumbling is still degraded.
