CPUCores March 2018: More Updates!

Want even more FPS gains? You got it!

CPUCores is getting even more significant upgrades in the near future!

CPUCores was first released on Steam on July of 2015. Since then it has had around 25+ major updates (announced), with around 20 more minor updates (unannounced). During that time, we've released tons of new features, enhancements, and improved support.

We aren't stopping there!

Here are some updates that are being worked on:
  • Re-release of our "service based engine". We are working on tweaking our prior test release of a service-based method for the software to internally make FPS-improving tweaks. This development is a ways away, though once finished, it should provide even more FPS gains.
  • Ability to hide games from your CPUCores Steam game list. By popular demand, we are added the ability to hide games in your Steam library from the list that is shown via CPUCores.
  • Further tweaks to the Game Probe Detection (GPD) feature of CPUCores. This will enable you to easily scan your processes and add games to your GPD list and save them there, allow multiple games to automatically be detected by CPUCores and have CPUCores auto-engage when a game is seen to be running.
  • Better support for more languages!

Further, we've opened up a discussion thread to hear what YOU would like added to CPUCores. See here:

“OMG best 16 dollars i have spent in years. EVERYTHING is faster smoother and just plain better! Awesome software!”
Thumbs-Up – Tarnis

“I just wanted to let you know that this works amazing for me on most all of the games I have tested so far, and Some of them I get a pretty big FPS boost... Thank you for this amazing tool :-)”
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

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.
