Really Random Lag Issue

[Izzy]

It just happened again. Noticible FPS drop, but the game is reporting max FPS. This is with CCC uninstalled.

I used to have this exact same problem. I have a Nvidia card and EVGA Precision utility. I tried all the same things with mine. Uninstalling and reinstalling drivers, running driver sweeper, etc. I did a bunch of searching and finally found a solution.

Add/remove programs > Add/remove Windows components > Uncheck "Networking Services"

I have never had a problem sinse. I don't network this PC so having that disabled is not a problem for me. I'm not sure if this will work for you but it's worth a shot.

That's a pretty random fix lol. It's not really gonna work for me though since I mostly play MMOs on my PC.
