alright mate, that "geo" with 62.7 next to it means that it's taking 62.7 ms per frame to render your geometry.

that explains why there wasn't much of a difference between 5 objects and 55 objects -- they aren't the problem (though you could so easily use lower poly-counts without any visual impact).

someone else can tell you what to do about your geometry, because i personally avoid level geometry.
