And although I exchanged my graphics card from a GTX 660 to a Palit GTX1050 ti and although when I play Fortnite I assumed sound laggs I shoot the sound from the shot is delayed, i.e. When I shoot the sound doesn't come directly after 1 second or when I build it building noises come later although i have already built.
The sound lags do not come from the graphics card but from the mainboard
maybe the mainboard is a bit older and the sound chip is no longer matched to the more recent titles.
only a new main board helps
