I have tried this, but it does not work as expected. If there is just the grid and nothing else, everything seems to be working: it isalways antialiased. But if I start a new project (for example, with a sphere) antialiasing only works if I'm rotating or moving a view, and stops working if I do not do anything (so if I stop rotating the view, everything becomes not antialiased). This seems to be a bug, because even if I just hold middle mouse button without actually moving a view, antialiasing works, but stops working immidiately if I release the middle button. Antialiasing also does not work when I'm doing brush strokes.
I'm on Linux, I have NVidia card (GTX 680) and I was trying latest demo. Is this a known issue and if it is, are there any plans to fix this? 3D Coat seems to be a great program and it could be just what I needed but I do not feel comfortable using a software without antialiasing, it is too distracting. Is there any workaround?
