664mc low fps on ASIAIR Plus

QDRA28SX

Connecting my 664mc to the ASIAIR Plus and going into video mode, I'm surprised at the fps being, at most, 15. Connecting the camera to my PC with ASIStudio, the camera reaches ₆₅ fps with basic settings.

In both cases, I'm using USB3 ports on both PC and ASIAIR Plus.

Please advise on how to reach expected fps with this camera. Available configuration options on ASIAIR seem very minimal.

QDRA28SX this is due to the hardware limition of ASIAIR, it can not reach the max fps of the camera.

Can you detail exactly what is the hardware bottleneck for the ASIAIR? The only hardware requirement stated on the 664mc is the USB3 port, I'm surprised by your answer.

QDRA28SX Due to the CPU limit, ASIAIR can not handle too high fps with high resolution.
