When the fsx running, my 2 or 3 cores work at max. but 1-2 cores work at %20-30.i have onlythat tweak:

[JOBSCHEDULER]AffinityMask=14

is there any solution for this problem?my cpu is AMD X4 630 2.9 ~ 3.4 ghz

For a quad core try using AffinityMask=15

Affinity mask 14 uses 3 cores (Binary 1110) This is the correct setting for FSX as it leaves core 0 to run the o/s and background processes resulting in a smoother sim.Affinity mask 15 uses all 4 cores (Binary 1111) and there seems little point to this.I did read somewhere that this line is irrelevant since SP2 though.IAN

Affinity mask has always confused me.. some say use 14/15 or 12, some say use 84/85 (cuz of HT?) some say use 254/255).Currently using 14

This is not a problem, but exactly the way you want it to work for smooth flight.Affinity Mask=14:For a quad core, Core00 is running base code only, Core01 is running the mainFSX threads, and Core02 and 03 are dedicated to scenery and texture loading.

Still relevant
