HackRF is able to produce stable picture / color / sound only at 9.7-9.8Msps and fails at 10Msps or greater for 2 digital LG TV sets from Windows about hacktv

You can try to change in the bios (or windows) some power saving options, in order to ensure that CPU frequency will run at "performance mode" and will not lower its frequency, it may improve the results and reduce the latency of the laptop.

Try also to increase process priority for hacktv in task manager :

I turned OFF BIOS setting "CPU Power Management" - the issue still persists ((

Also I tried to change Windows 10 power mode from "Better Performance" to "Best Performance" with no effect.

Next logical step is to set HackTV on some live Linux and try to boot a laptop...

@Potomac I also tried to change priority to "Realtime" and affinity to a single CPU - it didn't help.
