Hi, I’m having the same issues. It looks as if there’s some sharpening effect active in the viewports, which creates bright pixels next to the edges. A bit like unsharp mask in photoshop.
I hope this gets addressed soon. R8 is hurting my eyes and I am quite surprised R8 got released like this.
Compared to other 3D programs that I am running, Rhino8 looks like going back into time 25 years. Happy 25 anniversary by the way :D.
R8 has lots of nice new features, but drawing and displaying lines is the utmost basic of a 3D program and shouldn’t be forgotten.

Absolutely.
We won’t be heard, but that’s also part of what I reported in the past months.
Something should be done.
Yes line quality is a big step backwards in Rhino 8.
Hope to see a fix

Absolutely true!
Curves were not perfectly aligned to pixels, that came in V6.
In theory the V6 feel should be even better, it’s not, I can’t explain why.
V8 needs some love.
correct . It needs a lot of smoothing and improvement. He looks fragile now

I’ve found a possible fix using the nvidia control panel that I posted over here.
These settings do nothing for me unfortunately, still terrible AA
FWIW, I’m on an RTX 3050 with the latest drivers (546.33). Also, I had to exit all open Rhino instances and re-open for the settings to take effect. I’ve noticed over the last few hours it’s been a big improvement on my setup but I think overall Rhino 7 is still looking better. I recall having a similar issue when either 6 or 7 came out, I had used the TestWireThicknessScale setting to get through that one until they got it fixed.
I’m having the same anti-aliasing issue. It looks horrible in Rhino 8.
I made the changes suggested in this thread to my NVIDIA Control Panel. This seemed to help, but it’s still noticibly worse than Rhino 7.
I would really appreciate a fix to this as soon as possible because it’s quite straining on my eyes.

Amazing Gijs kudos to you! Thank you very much. 
This is now working great in combination with this advanced option setup:
