half way the game, i did this :-
1) during the game, i go to Option
2) Exit to Main Menu
3) go to Settings
4) Change RESOLUTION to lower then SAVE
5) this message came out

above error appear when i halfway playing the game, exit to main menu and changed the setting and save.
but if i change the setting before the game start is ok, no problem, fine.
if and only if after i started the game, then go out, change the setting and save, this message appear.
Conclusion, the above message will only appear if the game had started then change the resolution by quit to main menu.
if the resolution change before the game start. it is fine. no problem at all. BUT, if i quit to main menu after the game started and change the resolution to higher or lower, message above will appear.
i'm not complaining. but a feedback to hope such problem will be solve for the next patch.
i still can play the game without having any problems. the only thing i need to do is, do all setting, then start the game without going back to the main menu to change the resolution.
