We’ve created a strategy multiplayer browser game with the power of ThreeJS! We just started a fully functional and absolutely free beta. If you got curious, take a look: https://riseintime.com/.
The performance was one of our biggest concerns. One of the biggest things we learned regarding performance is to make use of InstanceMesh whenever possible.
For the mobile version, we completely left out real lighting and shadows and worked with Matcaps instead, to further optimize performance.
For the controls, we used OrbitControls and adjusted them a little for our needs.
I’d be happy to hear your opinion on it
