If 2.5 msps mode is working relatively well, I'd look at your CPU utilization in the two modes.
What CPU and how many cores does the computer have?
Take a look at Task Manager (Performance Tab) to see what the CPU utilization is when running in 10 msps mode. If the CPU utilization is too high, that can cause the Airspy to not work well.
(BTW, in Win10, right-click on the graph and select "Change graph to Logical processors" to view all the cores.)
Also, can you confirm the Airspy is plugged directly into the computer and not into a hub?
