Optimization "height map" while driving and FreeCamera

[Alex10]

I tried to make a simple FPS on the "height map".
I put an example  http://www.babylonjs-playground.com/?14#  freeCamera and set her property:

camera.checkCollisions = true;

then begin terrible brakes. Everything starts to work very slowly.

 

Is it possible as it is optimized?

I have edite your scene.

that more your scene grow up with a lot of accidents (mountain, hill ...) and a very strong subdivision, detection of collision will be very costly calculated.

with what I did, the fps is still correct and you forget to apply gravity to the scene too.
