Every time I try to save my video configuration the game does not save the setting.

I go to

• Video > Advanced Settings > Ambient Occlusion - And set it to 'Low'

Then, I save the setting by pressing 'ESC' and then go to my game as normal.
If I do anything in my menu (search for a new match for example), the setting goes back to the standard 'High'.

Not sure what is happening here and it affects my game since the performance is lower when compared to the other players.

Can you check what is going on?
