Anti aliasing is not possible to activate at the moment (even with command line options) but I am thinking of maybe adding an anti-aliasing option later on.
Thanks.
I tried FXAA in nvidia control panel and it helps a lot :)
However force 8x AA (which should be best quality) doesn't work.
Glad to hear that the nvidia FXAA helps (That is a similar anti aliasing method to the one I would probably use for the build itself).
