Question In-game vs driver based performance

[r_jackdaw]

can anybody explain why did I get low performance with adjusted driver settings whilst I get better frames if its on default

NDriverDEFAULT
(Let 3D Application decide)

NDriverADJUSTED
(Max Frame 60fps + Powermanagement maximum performance + Sync off / Fastsync on)
