Methods
measure()
measure(): Promise<number>
Measure fill rate by rendering a series of noisy, semi-transparent point primitives.
Returns
Promise<number>
Primitive/point rate estimate in primitives/second.
Remarks
This test is quite inaccurate and does not match close to the nominal primitive/triangle rate of a GPU, particularly on tile based mobile GPUs. Points are being used instead of triangles since they more closely reflect the maximum theoretical primitive rate of most GPUs. The result should only serve as a rough estimate.
