I'm sorry, but I am not sure I understand.
Are you saying that FSAA and AF is adjustable via the in-game settings?
Not customizable, and those that can be enabled or disabled. If the game settings and system specification allows it turned on.
2.05 - Enable|disable AF
2.06 - Enable|disable AA
AA available if 2.07 is enabled
I have all in-game settings maxed and still have aliasing issues (my resolution is 2560x1600).
To make the game does not decrease settings in loading time in such high resolution you must have a very fast PC.
Is there a way to force it through Nvidia Inspector?
To force something in the drivers - 100% of the way for bugs and glitches.
It is better to put screenshots of where you think the AA does not work. Because players usually understand under AA all that just anywhere.
