Is it possible to configure SketchUp to use external GPU ( Razer Core X with RTX 3090 24GB VRAM) instead of the internal one (AMD Radeon Pro 4GB VRAM)?
When I run V-Ray, I can select my eGPU for renderings. But SketchUp still use the build in when I check in OpenGL setting:
I am interested in this answer as well.
SketchUp does not decide what to use, it only displays which the OS is using.
Thanks to your reply, it gave me a hint on how to force SketchUp to use my eGPU 
So basically all I needed to do is to go to Windows Display Settings, and under Multiple Displays I selected input 2 which is the eGPU. Now SektchUp is using my eGPU with RTX 3090:
I am noticing that SketchUp is faster, even in the viewport, models are faster to work with, not just rendering. Also anti-aliasing jumped to 16x instead of 8x and now models in the viewport looks super smooth.
That is really cool how do you connect and use an eGPU.
I can try helping you. What are the hardware of your eGPU?
In my case, I am using Razer Core X which is a GPU enclosure (t.ly/Ysfl) with RTX 3090 installed inside it. Then the Razer Core X is connected to my computer with Thunderbolt 3 cable … so you must have Thunderbolt 3 in your computer. After that, I installed the latest nVidia studio driver and WIndows recognize the hardware and that is all.
Man that sounds really slick.
Even though eGPUs are designed for laptop computers, you can use it with desktops as well.
Im running Ventura 13.2.1 on a imac and I’m having severe lag issues with Sketchup Pro. I bought a Razer Chroma x processor with an AMD Radeon RX6800. The mac is recognizing the eGPU in all programs other than sketchup. Is there a workaround for this?
