The Affinity Mask Calculator has just been enhanced to include the conversions from Affinity Mask values back to CPU combinations. Operation is as simple as 
entering the Affinity Mask value in decimal via the keypad provided. To choose between the calculators, just click on the title bar for the conversion required.
Note that the maximum Affinity Mask value Continue reading
Affinity Mask could bring improvements to flight simulators. But the question is: how can we tell from a hypothetical value (or more precisely a CPU combination) that it will bring positive gains to our system before we put it in the configuration file (fsx.cfg or Prepar3D.cfg) ?
Frankly, I don’t have a good answer myself because there are so many variables involved. However, following is the approach I take to precheck the performances from different Affinity Masks in realtime, then thru which I pick the one I think the best for my set up.

Affinity Mask is commonly recognized as one of the most useful features that allows flightsimmers to improve system performance by altering the combination of running CPUs assigned to the simulator.
Here’s my Affinity Mask Calculator (with redesigned interface) version that I hope it could give you some helps during your search for the best possible value.
Using the calculator is simple and intuitive — just select the CPUs you want to assign to FSX or Prepar3D based on: Continue reading
