If you've to spend money anyway you could better spend it on a Mesa card or Remora compatible device. With a hardware stepgen the 60-80 uS is ok. Otherwise there is a topic about the Orange Pi 5 which has a very low latency, Guglielmi has made a HAL component for the GPIO which he will release after has tested it.

You could try some kernel parameters to improve the latency if you want to, you can find several in this thread.

But this thread is actually to show your results. for questions it might be better to start a new topic.
