There is a “Display” tab on the general “Options” window of ArcGIS Pro 1.3.1. and there are three antialiasing related setting: “Antialiasing mode”; “Text antialiasing mode” and “Enable hardware antialiasing”. The first two can be {None | Normal | Fast | Best}. If I change the first two to “None” (there is no antialiasing), then the third option “Enable hardware antialiasing shouldn’t have effect. But it has, especially on thin lines (typical antialiasing), at least in local scenes. I think I misunderstood something. These option are working separately and the first two is only for software antialiasing?
