I appreciate the technical issues here as I actually have written code for flight simulation in C++ and memory management is a nightmare. This is even worse with the additional issues of differing drivers for different platforms and MS’s need to have a lowest common denominator (XBOX) for the basic capabilities.
Good luck and if I can do anything to try and peer into my 128GB cache to see what it is actually doing, ask. It seems to be a black box. My test is the FPS of the rendering of runway textures… with my 3070ti I have had to texture resolutions of Medium and various other tricks to get acceptable FPS. I do note that it appears to me to run faster after many take offs and landings on the same runway… maybe an illusion…
