If you're talking about Game Mode, all that does is bypass the signal processing routines to improve input lag. Game mode can still run with any Picture Size setting e.g. 16:9 or Screen Fit.TV needs to be set to PC Mode
As mentioned the important part for achieving the crispest picture is to achieve 1:1 pixel mapping, that is zero overscan added to output from PC and zero underscan on the TV (e.g. slight zooming performed by 16:9 Picture Size setting).
