Rhino BETA for Windows is using Direct3D as the primary GPU accelerated display technology. What is Direct3D? Direct3D is Microsoft’s technology for communicating with the GPU to draw 2D and 3D scenes. It is an alternative to OpenGL. [Direct3D Support | New in Rhino BETA] The entire d…

Thank you for your report. I have logged this issue with our development engineers. RH-98334 Rendering: The shadow quality of objects in a large scene is poor

Personal benchmarks on a very heavy assembly imported from Solidworks, using TestMaxSpeed command. (Btw, Rhino 8 failed to import the SLDASM file, but Rhino 9 succeed). Specs: Intel Ultra 9 185H 64 GB LPDDR5 Nvidia GeForce RTX 4070 Laptop 8 GB (Driver Date: 5-3-2026 Driver Version: 32.0.15.9647) …

Hi Kirill - [image] Kirill: Personal benchmarks on a very heavy assembly imported from Solidworks, using TestMaxSpeed command. Without a 3dm file, it’s hard to tell, but this is likely on the list as RH-98352 Curve redraw is slower than in Rhino 7 -wim

Hi Wim, Thanks for the reply. Unfortunately the model is a production/NDA piece. It consists of about 2600 polysurfaces. I updated my previous post and added Rhino 7 to the benchmark. Sadly, Rhino 7 is ~3-5 times faster than Rhino 8 or Rhino 9. Huge gap in performance.

Hi, and thanks again for the work that has already gone into improving Direct3D point-cloud performance. I did some further testing with the latest Rhino 9 Beta (9.0.26251) on a fairly large point-cloud dataset. The model originated from an E57 containing 370 individual scans, and the resulting 3DM…

@Matteo_Falduto I’ve been focusing on display optimizations over the last couple weeks and am still working on them. I completely changed how point clouds are drawn with Direct3D. Clouds with transparent colors haven’t changed, but other types of clouds will hopefully be much faster now. It would be…

I should mention in general there have been a ton of optimizations made in the last two weeks. If you have a model that you feel is still slow after using today’s beta, I would love to know about it.

no geometry on the screen. Just native display.
