Not really, at least in my case. As I said above, at 1440p, my GPU simply doesn’t need to push that many pixels. It doesn’t matter how efficient the CPU is, the engine just isn’t that graphically demanding that I should be running 100% GPU usage down the Grand Canyon near sunset. This is not Cyberpunk with raytracing enabled, or Portal RTX. THOSE engines will push your GPU to whatever limits it has. MSFS won’t.
The only way the GPU should loaded under those circumstances would be if the new engine offloads pure computational tasks like CFD and turbulence to the cuda cores, or if they’ve got ray tracing working silently (e.g. no setting to enable/disable).
