In low geometry levels, "optional" objects, marked as such by the track, are supposed to be removed. This provides a massive performance boost, at the cost of uglier graphics and of affecting gameplay on some tracks (see #5052).
But in most situations, these objects are not properly removed.
While I am considering removing this possibility altogether for 2.0, it makes more sense to fix it for 1.5.
