It is possible to get Sketchup (latest version) to anti-alias to screen in real time. The lines in Sketchup are all extremely jagged…
Fwiw, I am using Windows 8.1 (Pro x64) running Graphics card: ATI Radeon HD 5770.
I am still very much trialing Sketchup and do not want to spend any money getting rid of the jaggedness of lines.
[I am used to using Xara Designer Pro which has been anti-aliasing very fast in real time for over a decade]
Fwiw, I am using AMD Catalyst Software Suite (v15.20) and AMD Catalyst Control Center (v2015.0804). I also have something called AMD Gaming Evolved (powered by Raptr) but I have no idea if gaming is relevant to Sketchup (although both are 3D…) ??
Apologies for the newbie question…
