Once you get to certain high speeds on the trains, the wheels start to have graphical flutters, almost like they're exploding from the speed. It goes away once Post Processing is turned to low.
Hi, I get wierd stuff happening when an HST goes past - it looks like the side of the coaches are going across the track. Also have been past Slough a few times and the platforms have vanished. I even found myself travelling across the track bed gravel - with no track showing!
