I want everyone to look at @MichaMMA’s screenshot and note the number of private bytes that flightsimulator.exe is demanding in relation to all the other processes his PC is running and how little memory is sharable.
Since Resource Monitor is limited in scope and not a good tool to debug anything, it’s hard to tell the actual amount the simulator actually uses. But the high number of privates bytes indicates that a lot of the commit is actually being actively used in some way.
