Illustration: MSFS making good use of multiple cores

[KiloWatt]

Hello everyone,

 

We've all seen the claim repeated that the sim only uses one core. Today I had the perfect demonstration of it using all four of mine rather well and figured I'd share it here. Granted, this is in DX12 mode, which I understand uses the hardware differently.

 

See the two screenshots below of Task Manager; specifically how it reports CPU usage by program and also per core, on the second image. You can click on the images to enlarge, if it's too small.

 

 

 

All this is not to say that one thread won't dominate the CPU time - that would be the main thread that runs the show. Those of us that are CPU limited (like I frequently am) are then limited by the CPUs capacity to process the main thread. But there ARE other threads constantly working, and they are juggled by the various cores of the CPU.

 

And yes yes, I know it looks funny seeing a mere 4 core / 4 thread CPU in 2022...give me a break, haha.
