One thing that is clear is that chengelogs are very incomplete, so it's not a feeling There's usually 2-3 times more changes than mentioned in changelog - like changes to reflections, shadows, tyres - none of it is mentioned in bulid 107 changelog. Just like changes to headlights weren't mentioned in build 101 changelog Tyres seem more like build 90 now, so perhaps something actually was "disabled" in build 101. I like these tyres better than the ones from build 101. I've made some comparisons and framerate increase is approx. 10% in this build for me. I guess that's at the expense of reflection update rate.
