Been using this for a few years and haven't had any issues. It makes my older CPU (Ryzen 7 3700X) perform better in games and thanks to it my 16 gigs of ram are still enough for what I do. (Playing g... See more

not just good for gaming
use it on my older laptop for studying and it runs way smoother than just a normal windows install
I just came here to give 5 stars
I just came here to give 5 stars, what an absolute joy after installing fresh windows, especially getting rid of edge part and disabling windows defender. Windows feels snappy now. I do not like edge only because it does so many task schedular events thus background process tend to mess up action shooter games. Love atlasos.
Overall awesome experience
Overall awesome experience, more performance less ram usage it's very great! I would have put 5 stars if I didn't lagged when I left click on my background.
Gaming OS
Been playing around with tweaking windows for years. Thought I'd give this a shot. My system overall responsiveness feels amazing. My latency is more stable and gaming improved by a lot.
Doing a FFXIV benchmark my 1% lows went up 10+ FPS and my average also went up 15-20+ FPS.
In Elden ring with FG I went from 200 FPS to 250FPS.
It was super easy to set up. What amazing work. Keep it up.
Best playbook of all time
Best playbook of all time. Works for any system, lowers latency and improves fps all around the board. Nice server and frequent updates. But the discord techies are way too serious lmao.

Atlas Improves FPS even on win 11
I was on win 10 without atlas and went to win 11 without it too. After changing I felt the extra delay I got. Downloaded atlas and all the delay went away. My performance got better using atlas os on win 11!

Enhanced Performance in Rust with AtlasOS
I've successfully installed AtlasOS and made adjustments to the NV settings along with tweaks using MSI Afterburner. In Rust, which is my primary game, I've observed a significant performance improvement, with my average FPS increasing from 85 to 90 to now averaging 135 FPS.

it made my pc faster and smoother best os
Overall super nice experience
Good support, FPS Boost was noticeable went from avg 200-250 fps (valorant) to around 350-500 using the new v0.4, SIGNIFICANT decrease in input delay, and yes you can feel it alot atleast in valorant, overall its a very good product and im happy with it so far
NOT futureproof but it works, I guess...
Reinstalling Windows every time a new Atlas version comes out just so the "irreversible" scripts and the "updated modules" work is pretty damn annoying. I wouldn't have installed 0.3.2 had it not EXPLICITLY said it would be fully upgradable to future Atlas versions but NO. At least it's fully serviceable with Windows updates.
That aside there's no option to disable the branding everywhere and most of the under-the-hood tweaks aren't explained unless you read their source code, which most people won't. They could be sneaking in scheduled tasks for all most people know.
It does, however, clean up some windows bloat but that's only the bare minimum I'd expect, and I don't notice anything else because they don't TELL you what else they do.
Super smooth experience
Straight forward installation. Works great on lower-end systems. Extremely satisfied with the idle CPU and Memory usage!
this atlas os give me good performance
Awesome Playbook!
Very good Playbook. Removed unnecessary stuff. Only problem is that the AI feature on the Discord didn't help me getting the Xbox services back. (It also removed them so I couldn't log-in to Minecraft.)
Good Fps,Smooth
The title says it all its smooth it gives me good fps in games on windows 10 i didnt try windows 11 yet but i hope the results are just as good on windows 11
Super smooth experience
Super smooth experience with Heavy Windows 11
Lowest system Latency compared to other Windows MOD
I really like it
We really need Atlas Control Center for better experience while set-up everything depend users usage and configuration
