Status: Solved by downgrading to Windows 10 Oct. 2018 Update.


Any help is highly appreciated, thank you very much.

Let's start with my system specs:
i5 6500, GTX 1080 Ti, OS and Game installed on SSDs, 16GB of RAM.

When the problem started appearing:
I've reinstalled Windows, that's it.

What happens:
I usually have 150 ~ 250 FPS and before reinstalling Windows the game was very stable. Every 20~50 seconds (it happens the most when facing enemies) those FPS drop to 0 ~ 20 for one second and then go back immediately back to being stable.
Happens even when practising with bots offline.


What doesn't happen during the game or the drops:
  • CPU utilization doesn't reach 90%
  • GPU utilization doesn't reach 40%
  • RAM utilization doesn't reach 50%
What I tried so far:
  • Reinstalling the game
  • Deleting config files
  • Using the same game files as before the os reinstall (backup)
  • Reinstalling Steam
  • Reinstalling Nvidia Drivers (latest)
  • Installing older drivers (418.x)
  • Enabling VSync
  • Using -high in startup parameters
  • Updating Realtek drivers
  • Updating Chipset drivers
  • Following this guide
  • Disabling XBox DVR features

I don't know what else to do... Please help me, thanks.
