Finally 60fps is achieved! And the new voxel rendering system is working!
The overall polygon count is reduced by the factor 10 and the level of detail of the trees and meshes is greatly reduced (the switch between lods is now barely visible). This not only means that we can render faster it also improves the speed of the physic engine (=> more monsters can walk around).
You see these 2 big blue triangles? The old algorithm generated 128 triangles to display the same surface.
And as we do not need so much information to create the triangles we could throw away half of the world generation algorithm. This means that world generation is now also faster. Will upload a new version soon.
