各位使用Rhino的老师你们好!我遇到了个难题求大家能够帮我解决!

老师您好,我在使用rhino8的光线追踪渲染时发现渲染缓慢,我电脑的配置如下:intel Xeon E-2276M处理器、NVDIA Quadro RTX 5000独立显卡(显存16GB),rhino的安装目录也在默认的C盘下,通过Windows后台管理器查看发现在使用光线追踪渲染时CPU利用率60%以上,而GPU利用率仅为5%左右,电脑系统设置已经给rhino程序设置了使用高性能显卡,在rhino内也够远了CUDA NVDIA Quadro RTX 5000✅,曾经使用RTX 4060显卡对同一个模型运行光线追踪仅需50秒左右,而这个更专业的显卡则需要2分钟以上,这个问题如何解决,我真的很急迫,求求老师们帮助我!

“Hello teacher, I’ve noticed that rendering is very slow when using ray tracing in Rhino 8. My computer’s specifications are as follows: Intel Xeon E-2276M processor, NVIDIA Quadro RTX 5000 dedicated graphics card (16GB VRAM). Rhino is installed in the default C drive location. Checking the Windows Task Manager, I found that the CPU utilization is over 60% during ray tracing rendering, while the GPU utilization is only around 5%. My computer’s system settings are already configured to use the high-performance graphics card for Rhino, and I’ve also selected CUDA NVIDIA Quadro RTX 5000 within Rhino. Previously, using an RTX 4060 graphics card, rendering the same model with ray tracing only took about 50 seconds, but with this more professional graphics card, it takes over 2 minutes. How can I solve this problem? I’m very anxious and urgently need your help!”

Hi drrd,

There are a lot of factors that can drive up rendering times, can you post a small example?


:sob: :sob: :sob:

Look into what NVIDIA settings (specific to your card) are the most optimal and change that in the NVIDIA control panel. Do this for
both the global settings and the program-specific settings. Also, in your windows graphic settings, assign your card to Rhino in high performance.

None of those things have anything to do with CUDA rendering.

It’s not something daft, like your A5000 has latched onto CUDA, while the RTX 4060 used OptiX proper (next tab along)?

Optix is a huge difference.

I’d guess the actual difference in generational architecture would be maybe 10-15% in favour of the 4060.
