Good day. I have just released a new build, which includes a Windows Service (FlightSimAutoCPUPriorityService.zip), which completely automates the process prioritization. No need to even click once on the console tool, the process will run in the background and make sure that your Flight Sim and DCS processes are always on high priority.
Just download and extract FlightSimAutoCPUPriorityService.zip somewhere, and follow instructions.txt.
Thanks.
