lag when looking around for first time

This is mentioned in the FAQ page of the Manual, but the solution doesn’t really work for me. … id_this.3F

Any ideas? Same “first time” lag happens again if I create a new light or project a texture.

[preload of models and textures?)

So the solution is rendering one frame after calling tht method, or updating to newer Panda? Because I don’t see any difference either way.
