Hi
While flying in career uses 100% of the GPU with 60-100 FPS, when I fly in free flight at big airport and using liners, the GPU goes up to 70-75% max and the FPS stucks between 15-25 at the airport (LPFG for example), and 40-45 FPS in flight. I don’t understand why this happens.
Big airports and big planes is more demanding on your cpu and hence the cpu cannot feed your gpu fast enough. So your gpu has to wait on the cpu and therefore your gpu usage goes down.
In sim-speak you’re mainthread (cpu) limited with big airports and big planes…
OK. But to be sure, mainthread limit doesn’t mean the CPU is at 100% or does it? Because in my case, it stucks at 60%. I have an “old” Ryzen 7 3700X, maybe I should switch to a better CPU.
