Marcus,
Attached you can find the results of the benchmark test.
I have been also compared the behavior with 2 different CPU and
different USB type 3.0 for the older tower PC, USB 3.1 on the laptop,
very strange the case of the older CPU generating an overflow every
minute.
The conditions were exactly the same in all test with no other visible
activity on the machines.
Release 14.0 seems a bit better with the benchmark but,sadly, the 2
UHD release are not comparable because the 14.0 as soon as generates
an overflow indication drops in the timeout with no recovery but final
consideration is that fast sample rate became unusable for long signal
recording regardless to software release and PC.
I really hope for a solution.

Nando:
Could you repeat the tests using num_recv_frames=128 and
num_recv_frames=256 in the device arguments?
--args type=b200,num_recv_frames=128
