Seem the graphical option may not be optimized and lower performance a lot.

Running it at the lowest graphical settings make it run well and can be playable at the expense of graphic who then look barebone. The text are readible and the default layout (WASD+Mouse) miss camera Right/Left that need to be added to the default layout.

It may need some tinkering/launch option to improve graphics while keeping decent framerate.

However, the game being rather a "slow" management game (as opposed to an action game), it's also possible to go lower framerate and using high graphic but it will eat the battery rather fast.
