For the fsx.cfg config file:
There is a tweak to control scheduling of threads on cores.
It is not recommended to change these settings unless you have a performance reduction and/or maxed out CPU loads in the PerfMonitor. The tweak is
[JOBSCHEDULER]
AffinityMask=n
where
n num of cores scheduled processor bit mask
1 = 1 core 0001

7 = 3 cores 0111
15 = 4 cores 1111
The processor bitmask shows you what cores will be enabled ( 1 ) and what cores will be disabled ( 0 ), primarily to allow you to see the pattern and be able to pick a bitmask for 8 and 16 cores or more when they are available.
There is additional code to reduce blurries. If you get random texture tiles that appear in a solid color this may help. In some cases, the textures generated from this code can get throttled and will be timed out. The time out config value is
