so when i play stuff like darksouls 3 on max its fine and smooth but then i play league of legends and it freezes or lags. i tried changing basically every setting i could and clean reinstall driver but it's still a problem. anyone know what would be the problem? it's gtx960 with 6350fx and giga ga-970 gaming. thanks for any help.

Are you running a beta driver?

i dont think so. its the latest geforce 375.70 from oct 27.

use like a 3 month old driver
and see if that works

Or verify file integrity of the game.
maybe its not the gpu at all since it works fine on ds3 max.
