RE: Bios A11 update for Inspiron 7520.
I think the new BIOS doesn't affect the games in any sort...though there were a few lags today but i am guessing that was bcoz of the new uTorrent version (which may be faulty. It is using large CPU resources).
A11 BIOS is fine. But in any case wait 1 or 2 weeks before updating to A11, for my another post about this BIOS fix.
