Affinity mask problem

[Alexander_Halbritter]

hi guys.

im having a i7 4790k HT on and i set affinity mask 84 in my fsx:se config. however i noticed, that CPU2 is at 100% all the time and the rest idles at around 20%. im not really getting bad performance with my setup but i think it could and should be even better with all Threads being used more. 

thanks in advance

FSX is using one (1) core for the vast amount of calculations. So it's pretty normal to use 1 core at 100% while all the others are idling around. That's the reason the affinity mask setting does only makes sense to prevent FSX to use 2 logical cores while it's only 1 physical core (on HT cpu's). For amd cpu's it does not make sense at all. FSX detect's amount of cores and uses it since SP2.
