[d3d9] TrackMania United Forever - Performance regression

[NorbertHarangozo]

Starting with 996acbe3f2eba97a6d3e725a8e7748aa0dd6764a, performance has dropped quite substantially. The exact degree depends on the map, the most extreme example I have found so far was going from ~160 fps to 67 fps on "StarStadiumB3". I used this map for tracing.
