Last night I had odd dream, that last corner of Toban was very difficult there, I consider dream being rather realistic as last corner is very difficult when I tested this track and when I drove this track in rF1.
However it might be more worrying that I had a dream about sim racing and my computer has been out of operation only for two days...
I did not notice big bumps or weird shadow issues (not in dream when testing this track), but I don't use shadows or hdr as my machine has not enough power.
