What controls wireframe line thickness as V5 V8 differ

Hi,
I thought I had gone through matching settings from V5 to V8
yet wireframe is far thicker in V8
what did I miss ?

Cheers

Steve

check these settings-

Hi,

Thanks, altering the 2 to 1 made the lines thinner, as per V5.
not sure what the other two do, as 1 is already 1 !

Wish we didnt have to go around altering things to get a crisp looking display.

Wish the ragged curve lines could be also fixed with a setting.

one called ‘quality lines as per V5’ !!!

very unsettling , one cannot trust where the line is, have to zoom in to see it is in fact ok.

Hi Steve -

Could you provide a simple 3dm file and screenshot of “ragged curve lines”?
Also, which version of Rhino 8 are you currently running?
