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.
Thank you, @stevebaer would you be okay with it if I sent it via a private channel (e.g. email)?
Of course private email is absolutely fine. I’ll PM you
just curious if it is known and acceptable to have Rhino 8 is always slower between (10% - 30%) compared to v7 when it comes it viewport performance. or is it still in the works? and If people are okay with this how can this presented to the end users when it comes to “Performance Improvements”

Here is a file that I work on and I can feel the performance degradation (on shaded mode), It is a Revit Export that has a lot of blocks, the performance disparity continues as I explode these blocks
Hi -
I’m not seeing that here. When I open your model in Rhino 7, I get 5.43 FPS from TestMaxSpeed. In Rhino 8, I get 7.48 FPS. Which results are you getting?
-wim
test file on RTX 2070:
Rhino 7: 12.80 FPS
Rhino 8: 11.90 FPS
For me there is a much more substantial improvement between Rhino 7 and 8. Rhino 8 is 2.7x faster for me.
Rhino 7:
Rhino 8 WIP:
This is on a PC with an NVIDIA RTX 3070 on a 4K screen. Both times Rhino was in full screen with no other programs running. The file was opened as is and TestMaxSpeed was run.

ps: Comparing to other results here, it seems that my Rhino 8 isn’t particularly fast, but rather that my Rhino 7 is really slow!
Here’s a test on another machine (RTX 3070 Ti)
Rhino 8 5.86 seconds. (17.06 FPS)
Rhino 7 5.61 seconds. (17.83 FPS)
Numbers I’m getting below:
Rhino 8: 12.93 FPS
Rhino 7: 13.95 FPS
After exploding the Block instances, I get these numbers:
Rhino 8: 33.68 FPS
Rhino 7: 36.36 FPS
The next steps for me are to 1- completely uninstall V-Ray 5, not just disabling the plugins, hopefully this can help a little bit, 2-Reset all the options / UI customizations that I made to Rhino 8 to narrow down the disparity.
one possible cause for that is also because I run a 2nd GPU as my OpenGL processor, will test it without a 2nd GPU as well
*** Update,
1- Uninstalling V-Ray didn’t make a difference since it was already disabled in the Plugins Manager.
2- Disabling my OpenGL GPU (Nvidia A40) and Keeping my RTX 4000 doing all the heavy lifting, it seems the margin of disparity has been shrunk to the below:
V7. 12.95 FPS
V8. 12.55 FPS
I’ll test my work machine tomorrow to get more information.
Thank you for the insights.
Why is the performance of Rhino with blocks so much worse?
Is this an unavoidable reality? Or something that can be addressed in future development?
