What I'm saying is that the orbit line widths are not measured in "pixels". They didn't make then "x pixels" wider than before. NOTHING in the game is measured in pixels. For example, the font size in the main menu isn't measured in "pixels". It's measured in a percentage of the screen resolution (most usually vertical resolution).
If, for example, the font size was, say, 100 pixels, then main menu text would look twice as small if you are using a 4k screen resolution than if you are using 1080p resolution. Obviously that's not what happens, and wouldn't make sense. The font size is, for example 10% of the screen's vertical resolution, and thus will always appear the same size regardless of which resolution you set the game to use.
The current orbit lines are not "2 pixels" in width, because that measurement, like with fonts and everything else, wouldn't make sense (like with text, it would make the lines thinner with higher resolutions, which doesn't happen). They are a certain percentage of the screen resolution in width. And all I'm asking is to reduce that percentage to eg. half or 3/4 of what it is currently.
