So, as the title of my post suggests, I haven't been able to get my Anti-aliasing level to stay above 1x in the menu, no matter how many times I restart the program to initiate the change to 16x or even 8x. I have an Nvidia GeForce GTX 1050 Ti graphics card, and, per Support's instructions, seen in the link below, I tried to change my NVIDIA settings in order to get a better Anti-Aliasing level. It still didn't work, and support was stumped, suggesting I make this topic and also submit a bug report.
Does anyone know what to do in this situation?

In video you have anti-aliasing set application-controlled. Force it to whatever level you want to achieve, x8, for example and it should work.
