What is a reason of zigzag edges on Rhino 5 Version 5 SR14 64-bit 22/5/2017?

That looks like an antialiasing problem.
In Options > View > OpenGL, play around with the setting. M
My hunch is you will like it better set to None.
My second hunch is you’re not running an nVidia display adapter which seems to do the best job of antialiasing.
AA happens in the display driver.

Thank you sir , i’m trying to fix that by update my nVidia display driver . i hope to fixing .
This is my Rhino options … Is it correct ?


Note that Rhino didn’t find any information about the driver date and version. A update of the driver might help that.
Also, you have the antialiasing set to 4. Try with both 8 and none.

… I’m not sure if that setting is actually used when the NVIDIA Control Panel > 3D Settings > Manage 3D settings > [Global Settings] / [Program Settings] > Antialiasing settings are NOT set to Application-controlled … I guess it’s best to check and make sure that these are set to the application.
