I am sorry, I made my post a little bite to quick.
I am not talking about the "real time" setting, but when you have for example 8 cores listed, from 0 to 7, 0,2,4 and 6 are actual CPUs, while 1,3,5 and 7 are logical CPUs. Even with a free flight with nothing but me I endure severe stuttering. When I open the affinity dialog for DCS only 0 is selected and with this method they do disappear. No placebo...
