Ihave the same issue. While in setup the automatic "enable game mode while in fullscreen" is (i guess) happening instant, when I exit the game it should take one minute (according to setup) until gam mode is disabled. Then I should have plenty of time to see it is in gaming mode.
I tried disabling the option to exit gaming mode, but still, after a game exit it looks like is not in gaming mode... Not when alt-tab out to desktop either. I have also put nod 32 in gaming mode from the home-menu of nod32 and it enters gaming mode with the orange triangle in the taskbar, but as soon as i exit the game (or tab out) it's not enabled anymore. I thought at least when you had entered gaming mode manually it would stay there until you exit it from the menus?
I love nod32, and have no problems with games (as of yet, tried two, Installed today - nod32 Antivirus v7 2014), but as far as I can tell it's not sticking in gaming mode.
Can someone please help me figure this out?
I am in Windows 8.1.
Sincerely,
