TL;DR: Hold LP while plugging your controller into your PC if it uses a Brook PS3/PS4 FB to start it in PS3 mode which has the full 1000Hz/1ms polling rate.

Disclaimer: I am only 100% sure of that this issue exists for the Brook PS3/PS4 Fighting Board Plus on PC. Please test yourself on your own PC if you have a different board/controller!

You can do so by installing the Windows SDK Debugging Tools:
https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/usbview?redirectedfrom=MSDN

Follow the instructions there. Once you have usbview.exe up and running, find your controller and check the Value labeled "bInterval" -- that will tell you how many ms the polling rate for your controller is. Find which mode on your controller has the lowest value (0x01 being the lowest), and use that mode!

If you are a Linux head like me, there is the program evhz you can use to measure polling rate in real-time, as shown in this video:
