I may have found a workaround the problem. The anti aliasing works in windowed mode. I have found a program which can turn windowed mode into BORDERLESS windowed mode. The results are that you can play in 1920x1080 with perfect anti aliasing settings in "fullscreen".

Soon I will create a guide in detail how to achieve it.
