It's because graphics and physics are separate, physics are much much much much much higher fidelity than graphics, same with rf1 and any rf engine based game, and pretty much any other sim, although some other sims definitely seem to do a better correlation between the 2. Highest fidelity ingame options doesn't mean the graphics and physics are perfectly visualized. This is almost impossible due to physics algorithms and general calculations being way way more complex than what can be represented in graphics without blowing someones computer up. Highest fidelity just means it's the highest fidelity that isi has allocated for the game to use. I agree that I hope ISI improve in this area, as nk pro, lfs, rbr and probably iracing all look better in this area.
