Many users find that while it excels at gaming, the lack of certain services can cause issues with daily productivity tools or specialized software.
A standard Windows installation runs dozens of background services that typical gamers never use. On a standard Windows 11 machine, the number of running processes is often high, but after applying Atlas OS, the process count drops significantly. For example, one reviewer noted that on a standard test machine, the number of processes dropped drastically, and idle RAM usage fell from around 3.5GB to roughly 2.0GB. This frees up significant headroom, especially on lower-end laptops and desktops.
Some modern games featuring invasive anti-cheat systems (such as Riot Vanguard or Faceit) or those relying on the Microsoft Store may encounter compatibility issues on heavily stripped operating systems. How to Install AtlasOS 21H2 they come bloated with telemetry
In the world of PC optimization, enthusiasts are constantly searching for ways to squeeze every last frame per second (FPS) out of their hardware. While Windows 10 and 11 are robust, they come bloated with telemetry, background services, and pre-installed apps that many gamers never use.
