Has anyone noticed that theres no difference between environmental map off and low. Im correct in thinking its the environmental reflections on the cars? or am i totally wrong?!
If you drive around slowly you'll see that Off only updates what's being reflected every 20 seconds. If you start in the garage and see the garage reflected, then drive out, you'll still see the garage reflected. Then 20 seconds after the last update you'll suddenly have the sky and surrounding walls reflected. Drive away from those walls and they'll still be reflected until 20 seconds later, etc. EnvReflections on low updates the reflected objects in realtime but only updates the reflections at something like 5 fps (if you drive past a tree you can see it sort of 'jumping'). High updates at what I'm guessing is the full framerate, so the reflections are nice and smooth.
