Nope. I was flying a session the other night on Live Time, and was on approach. Tower Freq tells a heavy, hold short Cessna Skyhawk on short final - that was me. I touch down, and haven’t even made it to the taxiway and I hear tower clear the heavy so I rev up and get off the active. As I’m contacting ground for parking, I hear the enormous rumble behind me and switch to external - there he goes, just rotated about at the same point as the taxiway.
FSX has more traffic, but today’s processors, memory and GPU can easily handle all of it at 100 percent. I sat at Ft. Lauderdale Exec for seven minutes on the hold short, three inbounds came in, and a Piper starting at me at the other side of the hold line, all of us waiting to take the active.
Turning on that much AI in this MSFS will bring a decent rig to it’s knees today.
