Interestingly, when I turn on the PC, it starts with all cores unparked. However, after about 1 minute, they are parked again (10 of then during the flight)
I tested turning off Hyperthreading. It only turned off the 8 logical threads, keeping the other 12. But in the end, it kept the 10 running during the flight (2 parked).
What I noticed (but I will do more tests) is that, right after starting the PC (when it still has all 20 cores unparked) is the best time to turn on DCS. But I don't want to conclude this wrongly. I will continue to observe if this behavior is true. null
