A glimpse what GT5 could become?

GT4 doesnt even run with 60fps....
The reflection is a map overlay, so the "textured tube" is the right discription just very simple. You can spot that on some tracks were you see reflections on your car that arent right, i cant remember which tracks that have though.
In GT3 you can spot that on the test course, just follow the yellow line in the 3rd person view and look at your rear bumper, you will see reflections from a line that isnt on the asphalt and vice versa.

If you're speaking about GT4 PAL then you're right it runs at 50fps, but NTSC at 60fps same with the reflections.

You are right about GT3 and the textured map system but GT4 as stated on the game development interviews was upgraded from precalculated(GT3) to "realtime reflections". The vid that I posted speak for itself.
