CPUCores Update 1.8.3!

CPUCores was built to do 1 thing and 1 thing only: Increase your FPS!

Version 1.8.3 has been released - This is a minor but great update!

New CPUCores 1.8.3 Updates:

  • There is now a minimize to tray option inside CPUCores (top right) corner for those who wish to minimize to the Windows task tray. You can still minimize to the task bar as well.
  • Application has been updated to better support the Turkish language.
  • The Windows process listing area has been tweaked slightly for Windows 10. This area allows you to use CPUCores on any process running on your system. This is especially useful for games who have unique launchers.

!!! Please Note !!! You may need to delete your old CPUCores configuration prior to running this new update. To see how just scroll to the bottom of this update release for instructions.

CPUCores has been updated recently which features our automatic Game Probe Detection!

About Game Probe Detection:

CPUCores has been updated with a brand new feature, currently in BETA, which we are calling our Game Probe Detection!

This new feature will allow you to input the .EXE of any game(s). Upon entering the game's .EXE file, you may then minimize CPUCores and then launch your game via whatever means you may have.

After inputting your game, CPUCores will "probe" your system continually until the game is launched. Once CPUCores detects the game has having been launched, CPUCores will automatically engage it's "START GAME" button and thus do everything that CPUCores is configured to do! Once you are finished gaming, simply close your game and click the "STOP CPUCORES" button.

This new update includes supports for games that require web-based launchers such as Battlefield 1, as well as classic game launchers including Battle . net, as well as any customer game launcher such as SKSE, F4SE, etc.

I hope you enjoy this new feature! As it is currently in BETA and is being enhanced, please report any bugs/ideas about this new feature directly to our Steam forums.


Prior Recent CPUCores Updates:

  • CPUCores has had a major GUI update! The software now is more streamlined and runs faster than ever!
  • CPUCores now has a much better Japanese language translation for the application. Japanese users rejoice!
  • You can now directly edit a Steam detected game's title as well as image right inside the software. This allows you to rename and better organize your auto-detected library of games!
  • CPUCores now supports command-line arguments to automatically start a game with CPUCores without using the GUI! To do so, simply navigate to the CPUCores.exe file and type a command such as: cpucores.exe /startgame 730 You would then type the appID for the game itself (730 is CS:GO)
  • CPUCores now remembers the last screen you had open when you closed it and then returns to your last screen when re-opened.
  • The Game Probe Detection feature has been tweaked to run even better!
  • Some of the CPUCores art graphics have been updated!
  • The CPUCores application has been updated to better support our incredible Chinese users! Thanks to a few people in the Chinese community, the software now has immensely better Chinese translations. Many thanks to Flan as well as TeRRy$ for their incredible help!!
  • The CPUCores Steam website has been translated into Chinese. Yay to our Chinese users!!!
  • CPUCores is testing 2 month long 25% off sale. Our normal $19.99 price has been reduced to $14.99 for two months. Enjoy the 25% discount!!!
  • AMD Ryzen CPU Support! CPUCores has been updated to now work with AMD's latest processors. The software will now automatically detect and configure itself to work with your AMD (or Intel) CPU.
  • VR Support! CPUCores now has direct support for the Steam VR headset (Vive) as well as the Oculus Rift!
  • Game Probe Detection has been upgraded and improved! This will allow you to automatically detect a game and engage CPUCores!
  • Favorites List has been added! You can now flag a game as a favorite and sort it to the top of your Steam games list!
  • Real-time Process List has been improved! You can now scan your system's processes and pick one to "CPUCores It" in a much more streamlined fashion!
  • Supports Steam Libraries > 1000 games! CPUCores Steam game detection has been streamlined to better support users with HUGE Steam libraries!
  • Various minor bug fixes including a license box pop-up, Game Probe Detection auto-starting when it shouldn't, and more.
  • Modified the method in which CPUCores communicates with Steam to validate your purchase. This should address the rare bug with a Steam user encountering the "Enter your license key" message from CPUCores. A big thanks to everybody for your patience while we worked on resolving this issue!
  • Improved the Game Probe Detection (BETA) by modifying the internal mechanics of how game scanning and activation/pausing work. This should improve handling of CPUCores when pausing it's operation while a game/program you've listed is still running and needs CPUCores to be set to the "pause" position.
  • Added support for Steam Launch Parameters! This enables you to set game-specific launch parameters for Steam, of which CPUCores' Steam integration will handle correctly.
  • Modified how CPUCores shows up in Steam for "Time played" due to Steam's internal API better handling of non-game software. Your hours accrued using CPUCores should now be better reflected, versus the past only showing often 0.2 hours despite potentially using it for hundreds of hours.
  • Streamlined the software to make it FASTER and better supporting games which use launchers as well as non-Steam games!
  • Added better support for Windows 10 multi-user environments and custom User Account Security
  • Added a Windows Notification Icon which has several options including the ability to reset the window position of CPUCores. This can be advantageous for people who have multiple monitors and frequently add/remove monitors which can sometimes cause a program such as CPUCores to appear on a "phantom monitor".

Thumbs-Up – Akiba

“This little utility has the potential to boost your FPS by a significant amount. The benefit will always vary but it WILL make your game run better if you're not a Windows user with the black belt in Optimization.”
Thumbs-Up – Six Of Saturn

Just Updated

  • CPUCores fully supports VR-based games!
  • CPUCores fully supports all launcher-based games including Skyrim, Minecraft, GTA-V, and more!
  • Fully supports Steam-based games as well as non-Steam games and applications!

About This Software

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 automatically detects all of your Steam games.

  • To start, CPUCores will isolate your entire OS to your first core.
  • Secondly, CPUCores examines and constrains key Windows services that are not essential and known to hog CPU resources.
  • Third, CPUCores examines and isolate key Windows processes to ensure a perfect balance of CPU savings without starving key Windows processes.

  • CPUCores will isolate and dedicate processing cores to be exclusively used by your game.
  • CPUCores will allow game-specific hyper-thread disabling/enabling.

  • 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.

  • Fully supporting VR games!
  • Support for non-Steam games
  • Support for general, non-game applications like video editing, graphic design and more!
  • Convenient game sorting options makes large Steam libraries manageable
  • Incredible community surrounding the software!
  • Direct contact with the developer for suggestions on feature updates!

The impact of how CPUCores will help with FPS depends on essentially 2 things:

#1 Your PC Hardware
#2 The game itself

Here are some benchmarks we've recently seen from our test system:

  • ARMA III - 17.5% FPS Increase!
  • Team Fortress 2 - 58% FPS Increase!
  • TombRaider - 6.3% FPS Increase
  • Left4Dead2 - 14% FPS Increase

The CPUCores application identifies dozens of Windows programs, background processes, and non-gaming applications, and immediately controls and isolates them to a subsection of your total CPU resources.

CPUCores will then free up a block of CPU resources and dedicated it specifically for a game. You can then launch a Steam game, or any game/program, directly via the CPUCores application. This enables CPUCores to control the processor usage for that game/program and ensure it has dedicated usage to processing cores. Your game no longer has to share resources with the OS / other applications.
