CPUCores is a cutting-edge Windows based software built by gamers, specifically for gamers, with 1 thing in mind: INCREASE YOUR FPS! CPUCores does this by micromanaging your Windows OS and non-essential applications.

CPUCores works with all games, including PUBG!

With CPUCores you can optimize non-steam games too!

All you have to do is go to the 'Other Games' tab, click on 'SELECT' and select your game!


PLAYERUNKNOWN'S BATTLEGROUNDS is a last-man-standing shooter being developed with community feedback. Starting with nothing, players must fight to locate weapons and supplies in a battle to be the lone survivor. This realistic, high tension game is set on a massive 8x8 km island with a level of detail that showcases Unreal Engine 4's capabilities.

PLAYERUNKNOWN aka Brendan Greene, is a pioneer of the Battle Royale genre. As the creator of the Battle Royale game-mode found in the ARMA series and H1Z1 : King of the Kill, Greene is co-developing the game with veteran team at Bluehole to create the most diverse and robust Battle Royale experience to date

How to configure CPUCores for PUBG

1. Open CPUCores, under the 'Steam' tab you should be able to view PUBG if you have it in your Steam library.

2. Choose the right configuration! You should try the default configuration first.

1. Disable hyper-threading – This disables hyper-threading for Intel-based CPUs. This option is disabled for AMD CPUs. You will want this disabled by default.
2. Game on dedicated cores only – This enables the game to run on it’s own, dedicated cores. This is very game-dependent so you’ll want this disabled by default.
3. Run game with higher priority – This causes the game to run at a higher-than-normal process priority. You’ll want to enable this by default on most systems.
4. Isolate and constrain the operating system – This allows CPUCores to control and constrain your OS and non-game applications. You will want this enabled by default.

3. Launch the game!.

What using CPUCores for PUBG will do:

When you will launch PUBG using CPUCores, multiple processes will happen:

  • CPUCores will isolate and dedicate processing cores to be exclusively used by your game, increasing your FPS and performance a lot by separating your game data and processes from your OS processes.
  • Your ENTIRE OS will be isolated to your first core. Also, CPUCores will examine and constrain key Windows services that are not essential and known to hog CPU resources.
  • CPUCores examines what non-OS and non-game operations your PC is running. It will do things such as constrain non-game programs to your first processing core.

This will cause your PUBG game to have the maximum amount of CPU available, thus giving it the highest potential for maximum FPS as well as improving frame drops / frame lag / FPS stuttering
