Zachiii Posted December 2, 2016 Share Posted December 2, 2016 Landing PMDG 737 at KLGA, I get the following data from Windows Task Manager: CPU Usage 55% Memory 5 GB Physical Memory steady at about 50% RAM 55% CPU Usage History (4 cores): first two cores are loafing at about 15%, last two cores are maxed out. (The last core seems to be dedicated to FSX.) Frame rate during approach and airport taxi down to 9 fps virtual cockpit and 12 fps outside view. I am concerned about CPU core usage. Is this normal for FSX or is the workload on my CPU cores imbalanced?

loki Posted December 2, 2016 Share Posted December 2, 2016 That sounds about right. FSX is mostly a single threaded program, meaning most of the processing can only be done on one core. It may use additional cores for loading terrain data and textures, but once loaded the extra cores will drop back down in activity. Link to comment Share on other sites More sharing options...
