NVIDIA update?

I put my pc back.

Then I start fortnite without updating my graphics card NVIDIA geforce 960m, everything is fine.

As soon as I update my graphics card and update it, the game is unplayable and doesn't even have 80 fps

Why is it that when I update my graphics card that it is no longer playable?

Hy,

do you use the Nvidia tool to update the drivers?

if no, download the tool from Nvidia and install the drivers there, if so

do the optimization for games. Here you can set the optimal flushing experience that the graphics card can offer, but it often screws a little higher, which means that you can get FPS drops in-game. You can then adjust the settings manually in the tool until you have found your desired setting.
