I'm not sure which sound device you have. If you have Realtek there are some posts at the end of this thread that may help. This is the latest Realtek audio driver Latest Realtek HD Audio Driver Version - Windows 10 Forums
If you have some other type audio drivers, check your motherboard's web site and get the latest audio drivers from them. If the latest Realtek driver does not work, try your motherboard's version.

If that doesn't fit or work, you may try uninstalling the Nvidia audio drivers. They are not needed as you already have sound drivers from your motherboard drivers and they can sometimes cause problems.

Some games are just poorly coded and will cause lags. Google the game and lags and see if there are others having the same issue and see if someone has a solution.
