Yes

Actually with DOSX we run at 40000 hardware interrups per seconds.

I think i will never go as fast on Windows.

So i need to make some harware (buffer) to help Windows.

But how much ?

The faster i can go on Windows, the cheaper and simpler is the hardware associated with it.

Thanks

Roland
