Hi all, I just updated to Rhino 8 and I have the same exact jittering issues. I also tried most of the proposed solutions but nothing helped. Are there any new solutions?
Also seems to only be an issue at 150% scaling.

I’ve had the problem intermittently in V8 (also previously in V6 on certain workstations), and changed my scaling from 150 down to 125% and it took care of the jitters. Thanks for the tip.
Correction, the problem is fixed at 125% scaling in maximized viewport. Still exists in a 4-viewport layout.
Update to the correction, today with 125% scaling the problem is back. Not sure if it has anything to do with updating to SR6. 150% still bad. Today the scaling has to be set at 100% to avoid the jitters.
Update to the update–later in the same day it’s jittery regardless of 100/125/150% scaling, in maximized viewport and 4-view.

May be unrelated, but update both of your GPU drivers first. Your Nvidia one should certainly be updated.
Just updated, same issue.

Updated again, no change in jitter.

Right now 125% scale is ok again with maximized viewport, jittery in 4-view. Jittery in all views at 150% scale. So random. Would love to resolve this.
I have the same issue. I just bought new laptop. NVIDIA RTX A2000 8GB.
When rotating in 3D, vieport is shaking and jittering.
Everything is up to date, I should even downgrade the the NVIDIA driver to have certified for solidworks.
What I have noticed:
The jittering happens only in shaded mode with “default lightning” and in my custom settings, where I also have set “default lighting”
If I change the lighting method to Custom lighting and turn of shadows, the jittering is minimal (I am not sure if it is gone at all since I feel hypersensitive to that right now 
Rotating and paning the viewport is supersmooth and nice in rendered viewport where lighting method is set to “Scene lighting” and checked “Use advanced GPU lighting”
In the scene, I have Sun and Skylight on, so the load on GPU is much heavier than on default light with just basic light.
That means, it is somehow related to shading with shadows.
Does anyone have any clue how to fix this.
I was also trying to tweak Nvidia panel settings, vertical sync etc as was recommended above, without succse.
It seem I have found the problem. It has something to do with Open GL compatibility.
When tweaking OpenGL settings in Rhino, the flickering dissepeared but quality was poor.
So in rhino, it has to be set to max OpneGL.
Going back to Nvidia panel, under Rhino settings, there you need to set OpenGL GDI Compatibility to “prefer compatibility”:
Now Rhino all the flickering is gone.

In the Nvidia control panel, (system/global settings/display mode &g sync) switching display mode to dGPU solved the problem. But also once I did that, I reverted back to Optimus to see if the problem returns. It did not.
