V6 Goal: Display Performance

4 posts were split to a new topic: Rhino locks up reading FBX file

Hi Steve,

On a Quadro 4000 I’m noticing a definite improvement in speed. So much so that files I make in v6 are no almost unusable in 5!

I still however get to the point where working with the massive files in Layout space is gruelling and I’m needing to turn objects or viewports off to move around.

One example, I had one mesh-dense model imported from another program and a highly detailed nurbs model together in the same viewport and I wanted to trace some shapes in Layout space. This proved pretty much impossible. Osnap struggled to snap and typing text objects was so delayed.

My solution was to create a jpg of the viewport and insert it as a picture frame object and trace my shapes over that (obviously deleting the original viewport).

I have two questions (which I know you’ve heard before):

  • What would be the best graphics card that would support all your graphic improvements and help in Layout space on massive files?
  • Is there any way to freeze a viewport so it behaves in essence as a raster version of itself and not load up the graphics card?


I doubt there is much a different graphics card will change in this area. We need to fix the slowdown by making some rather big changes to how the layout system is displayed. In other words, it’s our definitely our fault. I don’t know when we will revisit layout performance as there are other more pressing modeling performance issues that we need to focus on first.

Just downloaded the latest BETA and the performance is so much better now. Im using the Nvidia Titan XP card and I opened an old file from a past job that is 1.4 GB in size (not uncommon for my files) . Its tumbling around smoothly.
This is the Moon Tug from Independence Day : Resurgence. Modeled entirely in Rhino 5.


Wow; are those screen captures from rendered display mode or raytraced?

Its the “Arctic” Viewport mode.

Yeah, I get good speed on my Win10 Bootcamp 2015 Macbook Pro GeForce 750m on the retina at full res now.
So I agree, you have done a really great job! V6 is turning in to a smooth experience!


This is another heavy file. Around 1.2 GB file. Its a mix of nurbs and meshes. The hardware (clamp on gear ) are mostly meshes as they were to be provided by set dec so these are stand in. Despite that the model still was quite cumbersome in V5 and seems to move better in 6.


Artic view mode is doing a great job here! Impressive models BTW o.O


More fantastic models with beautiful results! Thanks again for sharing.

Hey Jorgen, does that MBP also have an Intel GPU? If so, I’d be curious if you can configure it so Rhino uses it instead…and see what kind of performance you get. Lots of recent tweaks and fixes should show better performance in the shaded and rendered modes.

No rush, just curious if A) It works, and B) How well. I’m getting decent performance here on a 13" MBP using an Intel Iris… If you have something different, then I’d like to collect information on it. Just trying to get a wider spread.


Hi Jeff, I would jump through burning loops for you, but “unfortunately” it seems to not be possible on this model when running bootcamp, as the iris is hidden from the system and doesn’t even show up in the devicemanager. I actually thought this machine was a single gpu setup, but I also searched the web quite a bit and it seems to not be possible.

OT: I bought an Acitio Node to run an GTX1070 as a eGPU system for this machine too, but that is not possible either due to something with the 750m, too bad, but I’ll survive now that you have improved the graphic speed so much :wink:

Thanks for a great product!

Thank you.

Confirmed! Super impressed!

Essentially (unless necessary) stopped using Rhino on Windows, but was feeling left out…:slightly_frowning_face:

So loaded beta onto a bootcamp MacPro with two AMD FirePro D500, and opened a (previous) ‘death’ (for Rhino 5) file with hundreds of inside/outside corner rounded perforations.

Most all modes, including wireframe, choke and stutter in Win V5.

All modes smooth as silk in V6 beta!

FWIW - Rhino 5 Mac chokes more than Rhino 5 Win on this ‘death’ file.

Somehow and someway, hoping the V6 Win drastic improvements are comparable in V6 Mac?

Yes, the V6 improvements will be seen in Mac Rhino 6.


@ec2638, Would it be possible to get this “death” file? I’d like to see it.


PM you later…

I baked some colored mesh from Ladybug 0.0.65. The colors appear to be correct in Rhino 5 but incorrect in Rhino 6. I re-generated them from Grasshopper 1.0 's ladybug 0.0.65. The result is finally fine. Any solution for the previous meshes? Have to re-generate all of them in Rhino 6?

Also, the Grasshopper preview of meshes are always there appearing in the view port. I could not hide them by hiding the mesh components or disable GH display. Any solution?
