ACMR

ACMR is abbreviation of Average Cache Miss Ratio.
ACMR is used measuring the effectiveness of vertex on cache in GPU.
To be brief, ACMR is number of transformed vertex per polygon.
When drawing polygon, Vertex is transformed from memory to GPU.

If all polygon are triangle, Even If ACMR is the lowest, ACMR can get 3.
Sorting triangle along to via edge , it is like triangle strip, ACMR can get 2.
