This is because the default sequence size at 2x speed is 40ms with some variation due to 15ms seek window and 8ms overlap. I made a build with a 10ms sequence size that produces similar results to Chrome up to 4x speed, 1ms produces slighter better results but the difference is subtle. According to documentation, a smaller sequence is more computationally expensive but I have been unable to detect any significant difference myself. I think 10ms is a good middle ground, below which there are diminishing returns. The seek window and overlap can be left alone as these values help smooth out irregularities quite well.
