I really do not know much about MS Windows. (And I am not
really interested in spending much time on it.) Linrad uses
SetPriorityClass(GetCurrentProcess(), HIGH_PRIORITY_CLASS);
in case the user wants high priority. I will allow the 
ultimate call:
SetPriorityClass(GetCurrentProcess(), REALTIME_PRIORITY_CLASS
in the next Linrad version. Seems silly that such a thing 
would be required. Did you try to set a more conservative (=lower)
value for max DMA rate?
