Testing a track and I have the following observation; once you start applying shaders to model objects the frame rate becomes very sensitive to view distance (even with scene frames with relatively few objects) especially with wet conditions selected.
My understanding is that mip-maps are created during track compile (I would welcome this being confirmed, or should I create mip-maps?) Would it be possible to disable or simpilify the shaders when the smaller mip-map are used to draw distant objects to improve the average frame rate?
