Myself and my colleagues have been having some difficulty with Rhino behaving very slowly when working on projects larger than 20 or 30 MB’s, most times no larger than 600-700 MB, though we’ve also been having issues with completely new template files. Things such as changing a layer name, re-arranging material order, or turning on off layers takes a matter of 15-20 seconds sometimes, but it seems like it shouldn’t be like that on an empty, or small, project? Even using control-Z to undo a step can result in the session freezing and crashing.
We’re all running computers with the following specs, or higher:
Interl® Xeon® Silver 4108 CPU @ 1.80 GHz (Dual processors, 32 core total)
64 GB RAM
Quadro P4000 cards
256GB PCIe SSD
We all use Flamingo to render, I’d try disabling that plug-in but I can’t seem to disable anything at all in Rhino, clicking the little check box in my plugin window to try to un-tick it doesn’t do anything. That said, there’s a few settings that can’t be changed right now. No matter what settings we try to set for our renders, such as resolution, quality, size, etc, nothing happens. It always defaults to the viewport, low quality, and 72 dpi, every single time. I’m sure this is a separate issue, but thought it worth mentioning.
Anyone have any ideas on what to do? Seems to me (though I’m no expert at all in PC’s) that our computers should really be able to handle these projects. They are not what I’d consider complex in any way, and are often no larger than a small shed in size.
EDIT: Just a few more notes, probably worth knowing:
- We are often in wireframe mode, not shaded or rendered.
- Orbiting in wireframe, or even changing from a front to a side view takes a good long while.
- When rendering in Flamingo, each pass can take upwards of 4 - 5 minutes, again, with projects containing maybe eight or nine textures, no background, no lights, nothing that would seem to me to make it a complex render, and as mentioned above, all at very low quality and low resolution.
- None of us work with multiple programs or Rhino sessions open.
EDIT 2: Just wanted to add this - I’ve just pulled one of the problematic files onto my personal computer, and opened it up - runs incredibly smooth, no lag in commands or orbiting or anything. The only difference between the work computer and my personal computer is that it’s A) just the 90 day evaluation software and B) no Flamingo. Is it possible that Flamingo is what is causing all these issues? My personal PC runs with 16gb RAM and a RTX 2070, shouldn’t my work station be blowing that out of the water though?
