it was for fifa 15 but surely you can try & find out the optimal settings for your opinion & pleasue for all the games. for fifa 16 as well.
i just turned off the motionblur & depth of field effects into my lod file. that's what i need to use for all fifa series. i always turn off the motionblur & depth of field effects. the game looks much better, sharpen & clear w/this method.
you may try my lod file if you want;

at last, here are my nvidia control panel 3d settings for fifa 15 & fifa 16;
display mode - single display performance mode
power management - prefer maxiumum performance
texture quality - high quality
negative lod bias - clamp
trilinear optimization - disabled
shader cache - enabled
& rest is default by nvidia 3d settings.
