Are there any settings in Rhino 8 WIP that can be tweaked to revert the graphics setup/performance of Rhino 7? Rhino 7 seems to run much faster (viewports, multiple detail views on the sheets) and Rhino 8 seems to freeze all the time.
It would be very helpful as I’m trying to use new features, but these slow graphics make it very difficult.
Run the Rhino command SystemInfo and post the results here.
Please see below - thanks, I wasn’t aware of this command:

Makes sense, I’ll try that.
Sorry, but that didn’t make any difference. The same layout with multiple viewports in Rhino 7 still works significantly faster than in Rhino 8.
If you are aware of anything that may be affecting viewports’ performance in the latest version, please let me know.
Rhino 8 is still in WIP, but it may be making more intensive use of some GPU features that it’s just not up to snuff for, it does date to 2017 and 5GB VRAM is not officially considered adequate for multiple monitors with Rhino…it’s more or less a 1060 with more RAM?
Makes sense, thanks @JimCarruthers. I will try to switch the workstation then.
I imagine that in the meantime there is no way to remove some of these “GPU features”? They are not listed anywhere by any chance in any of Rhino’s options?
That’s just speculation on my part, mind you…it may improve, but yes it is getting long in the tooth.
I may be out of luck finding another machine with higher specs (unless Nvidia suddenly open sources their drivers 
), so still happy to learn about any alternative way to revert graphics performance in Rhino 8 back to 7.
I’m not aware of any performance drops in Rhino 8 with respect to layouts. I’ll need a sample file that exhibits the problem to be able to fix it.
Of course private email is absolutely fine. I’ll PM you
