Rhino 8 extremely slow and problematic on new PC

[Madie_Vidler]

Hi,

I have recently upgraded my system a now operating through a PC instead a Mac. As it was a built PC, I am still unsure if my Rhino settings and preferences are set correctly on this new computer, as Apple seemed to have my settings correct form the get go. It is all quite laggy and even have trouble opening a layout tab as it will just freeze and autosave, even with one detail view.

I have looked through past discussions so have posted my system information below if that is helpful.

Everything looks fine, the openGL is on the big card. Rhino should run great on this computer for many years.

Primary OpenGL: NVIDIA GeForce RTX 5060 Ti (NVidia) Memory: 16GB

Soooo, you bought a laptop with hybrid graphics and rhino doesn't run right. READ THIS

Hybrid graphics laptops are more and more common if you buy a consumer grade machine. (I recommend buying a mobile workstation for professional modeling but these hybrid machines are quite prevalent in the consumer market, especially for students.) They tend to generate a TON of tech support here because of the way they are set up from the factory. Hybrid systems are built with 2 graphics processors. A low power graphics chip (typically Intel HD or UHD) and a high power graphics card. However…

Is this in a particular file or are you seeing issues in a simple file as well?

Thanks Japhy,

My files seem to be fine for a few days then they become quite slow, especially when starting layouts. I have tried all the tricks: purge, SalBadObjects, turning my detail views to wireframe only. My files at the moment aren’t over 500MB and with one layout, so its quite confusing that I’m experiencing these issues on a stronger PC with basic models.

This gives the story. According to this systeminfo snapshot you could have saved a bundle of money on that nvidia card because it isn’t being used at all.

Since it’s a desktop I believe that the Intel graphics output connector is separate from the ones on the Nvidia card. Could it be that you have your monitor plugged into the wrong video output?

On hybrid video laptops and notebooks I think the video card choice is done in configuration software so Japhy’s link would definitely apply, but for a desktop with separate connectors I’m not sure.

Also, the Nvidia driver is from early October, and while this should be OK for Rhino you might check the Nvidia driver download site for a later one.

To add on to AIW’s advice, on a PC the NVIDIA graphics will be on a separate “card” which has several video connectors on the rear of the box. The Intel graphics are the motherboard and the video connector will be on a panel at the rear of the box which also has audio sockets and USB sockets, and possibly others.
