Affects the likelyhood of objects being merged.
Higher values improve the framerate at the cost of memory.
Affects the likelyhood of more complex objects to get paged.
Higher values improve visual fidelity at the cost of performance and RAM.
Technically this is implemented as a multiplier to the merging benefit, and since
an object has a lot of vertices, sometimes in terms of hundreds and thousands,
and doesn't often need as much draw calls to be rendered (typically that number is in 1 or 2 digits)
this value needs to be large enough, as this is what makes
the merging cost and the merging benefit actually comparable for the sake of paging.
Technically this factor is a multiplier of merging benefit and affects the decision
whether displaying the object is cheap enough to justify the sacrifices.
