Question

How does it work?

The minimap is using WebGL technology to render the 3D map on an HTML page.

Will this minimap reduce my fps?

Usually, no. But if there are a lot of labels on the map, it may use more CPU resources.

Can I add a label in my other script?

Yes, you can. Read the wiki "Labels" page for more information.

Can I add a new building to the map?

Yes, you can. Read the wiki "Model" page for more information.

Why my map is lagging?

Try to disable your ENB effect, and switch outside the game using Alt+Tab, then switch back.
