Why is the Anti Aliasing option limited to 2x AA in my display settings?
You are using a graphics card in the AMD 4000 series.
Graphical corruption can occur on this card when the Anti Aliasing option is set above 2x AA. Because of this, we have limited the setting to 2x AA to prevent the corruption from occuring.
If you still experience graphical corruption, we recommend turning down your Resolution and Texture Detail as well.
We are working with our partners on a solution, which may be included in a future update. For more information about this problem please email our support team at email@example.com.
