Rhino 7 Raytraced very slow

felixrothermel0 · December 21, 2020, 3:21pm

Hi,

I have just upgraded to Rhino 7, but the raytraced mode is easily 10 x slower than the same file in Rhino 6, is there a setting I need to change??

Best,

Felix

In Rhino Options > Cycles, what do your tabs show?
I have the CUDA cores for my Quadro selected.

Hi John,

Same, I have tried the other settings too, but theyre even slower. So i have put it back to CUDA. I have an NVIDIA 2080TI by the way.

I dont understand why it is so much slower than Rhino 6.

We don’t have enough details to guess yet.
Maybe posting your Rhino SystemInfo is a good place to start.

If you have a 4k monitor maybe Rhino 6 reduced the resolution for raytraced display and that doesn’t happen in v7? (That would be a 4X difference)

Thanks,

That must be it!

RH-61467 Raytraced mode on UHD monitors is no longer smoothly responsive

Every time they update the software there is a new bug. Earlier there was a problem of transparency setting which doesn’t work below 40. Now the new problem… The raytracing is too slow that the software becomes unresponsive.
