I finally upgraded to a beast of a machine. I have V6 of Rhino but I’ve still been using V5 because V6 didn’t run great on my older machine. Now that I have a 4090, I was excited to try Cycles. But when I use a raytraced viewport, all I get is white objects and grounds, and it’s painfully slow for what I would think is the best card available to run it. An I missing something? I don’t even know where to start looking to troubleshoot this. Thanks.
You’ll have to upgrade to Rhino v7 to be able to use your RTX 4090. Rhino 6 has no mechanism to support automatically newer cards when they come out.
I might be able to compile a kernel for the RTX 4090, but not sure when I can get to that.
So to be clear, if I shell out for V7, it works great with a 4090?
I haven’t tested this myself, I don’t have an RTX 4xxx series card. Hopefully community members will be able to say if they work or not.
I do have an RTX A6000 and RTX A5000, works great with those.
Thanks, I’ll wait. I hope my expensive card isn’t unusable on Rhino now. That would be pretty bad.
You can always just get the Rhino 7 evaluation version to double-check if it works. I think it should work, I just haven’t been able to verify myself.
Ah, thanks I forgot all about evaluation versions! (derp)
Let us know how it goes
Well, setting to raytraced mode crashes rhino.
And now it’s working. So weird. I’ll keep testing, thx
Hmm, weird that it crashes, but the mechanism in Rhino 7 should mean that when a new architecture GPU is detected Cycles first compiles a new kernel. That can take a while - maybe this felt like it was crashing Rhino? Or did Rhino actually disappear and you had to restart it?
It was odd… it said rhino crashed, and I sent in a report, but then it started rendering, the window didn’t disappear. Most bizarre thing I’ve seen. Testing more now.
You probably will be able to get even better performance out selecting your GPU in the Optix tab under the
Tools > Options > Cycles settings dialog. This will have a similar compile delay.
Holy crap! yeah, that’s like 5 times faster or so! Way more useful! Thanks.
