A:Answer Mine came with Windows 10 installed, and once the laptop was done updating it offered me a free upgrade to Windows 11.
I’ve played all the Borderlands games on it, Valheim, Lost Ark, and Final Fantasy 14 at max performance. The only game that gave me a warning was Lost Ark, saying that my RAM usage was high. Even then I didn’t notice any real difference in the machine performance. It should run Maple Story fine, but I don’t know enough about LoL to say if it will run it. If it’s comparable to the games I listed in CPU usage though then it should be fine.
