If you are anything like me, you probably stare at your FPS, CPU/GPU utilization, and RAM usage while playing video games. Performance issues like frame drops, system latency, and input lag can put you at a big disadvantage, especially in esports games. I was in the same situation.
I didn’t have the budget for a high-end gaming PC to make my games run better, so I started searching for ways to optimize my PC. I stumbled upon AtlasOS and decided to give it a shot. On paper, Atlas is a package of tweaks and optimizations that removes bloatware from Windows and promises to make it feel less sluggish and clunky. While I was just as skeptical of these claims as any first-timer, the results were far better than I had anticipated.
It made my Windows faster and lighter
Goodbye bloatware (I’m looking at you, OneDrive)
As someone who finds startup services and apps that automatically open in the background super annoying, Atlas absolutely nailed this part of the test. With AtlasOS, my Windows environment pretty much had nothing except the essentials. OneDrive, AI features like Copilot, Microsoft Edge, Xbox Gamebar, Windows Spotlight, Phone Link, and many other apps and services that I never needed were all gone. After removing all the unnecessary junk, my computer felt much faster. It was a relief knowing my system resources weren’t being silently chewed up anymore.
Another inconvenience for me is Windows Automatic Updates, which, for some reason, always install right when it’s time to game. Fortunately, Atlas gave me the option to disable these, along with update notifications. I decided to keep the latter enabled, so at least I am aware if there’s an important security update pending. I also had to manually enable Windows 11 visual animations, which Atlas also disables by default. I found it pretty neat that you can choose which Windows features to restore.
This mod also disables power-saving features and might come in handy for owners of old, toasty laptops who want faster performance at the cost of lower battery life. I tried this on my age-old ThinkPad just for fun, and to my surprise, things improved in terms of boot times and how quickly I can launch apps after logging into Windows. All of this came at the cost of a significant drop in battery life, so again, this is probably useful for someone who works from home and keeps their laptop plugged in all the time.

The temperatures are also about to go insane.
My games got much smoother
FPS were largely the same
Atlas is faster than stock Windows for gaming, but not nearly as fast as the AtlasOS homepage claims. According to the official website, Atlas promises that its optimizations can boost FPS from 217 to 365, a roughly 60–70% increase in raw performance. Realistically, this is impossible, and in my experience, Atlas barely boosts your FPS.
However, there were a few areas where I saw noticeable improvements. While my FPS didn’t drastically increase, my games ran much better overall. Frame rates were more consistent, 0.1% lows got better, latency was reduced, and demanding titles like Fortnite ran a lot smoother compared to my stutter-packed experience on stock Windows.
Over time, as I loaded my PC with more and more software, it lost this initial shine. But even today, after upgrading to better hardware that gives me more FPS, I still have Atlas installed. Yes, it doesn’t make as much of a performance difference as it did on my lower-end machines, but it still removes the bloatware and unnecessary junk that I don’t want, even if my PC can handle it.
There aren’t specific system requirements for AtlasOS, so if your system can run Windows 10 or 11, it should handle AtlasOS just fine.
Privacy and security are in your hands
Yes, I want Microsoft Defender

AtlasOS is an open-source Windows modification, and as with any such project, it’s important to approach it carefully rather than trusting it blindly. One of the main concerns with mods like Atlas has been their approach to Windows security, as features like Microsoft Defender, Restore Points, and BitLocker are often disabled and are also categorized as bloatware. While disabling these can improve FPS, not everyone is comfortable sacrificing security for performance.
At first, I naturally assumed these security features would be turned off automatically, but I later realized AtlasOS lets you choose which ones to keep. Personally, I kept Windows Defender on since my experience with third-party antivirus solutions hasn’t been great. With Defender active, AtlasOS works just like stock Windows, offering the full suite of protections, including cloud-based malware detection, Defender Summary, and more.
So why isn’t stock Windows optimized?
If Atlas is so good, why doesn’t Microsoft just make it for everyone? Well, because it’s not for everyone. Atlas and other performance Windows mods like Tiny11 aren’t intended for everyday users. Not everybody is cranking 90s with 400 FPS in Fortnite, and not everybody cares about their Chrome taking 4 seconds to launch instead of 2.8.
The features, or what Altas calls bloatware, are all part of the convenience package WinOrdows offers. If it started giving everyone such optimized Windows, people would call it featureless and would likely switch to something that offers more. Though I’m sure performance freaks like me would love to see something like this.
Atlas is a great add-on to your Windows 10 or 11, specifically if you want your games to run better. Again, it is not magic; it is simply optimization done right. That said, you can head on over to Atlas’s official site and read more about the project, and if you do decide on giving it a shot and find it worth your time, make sure to support the creators!
