This is 100% my personal review, I am not paid to write this as a contributor but I wanted to tell people how good of a project this is.
This is for my "gaming" laptop I used before. AtlasOS has shown increased performance and better latency in the most common games around as of currently, example being Valorant (even though you don't need that much for that anyway) but I used to have to fidget with every games files to get the games working. Valorant FPS has improved by 2-3x what it originally was (around 60-80 FPS before). With Atlas I don't have that hassle and I can just play a game, sometimes I need to set low.
How does Atlas compare to other custom Windows operating systems? I wouldn't have a clue and you would have to ask other people on this one. But I would say if you are wanting a faster computer, try Atlas out. It will be worth it ;)
Also, 22H2 is amazing as of so far, so when it releases, you probably should upgrade!
Thanks for reading my short and simple review. There is more reviews on the Discord if you wish to check some more and don't want to take my word for it.
Happy and safe travels!
