For the ram usage, it is only high when near big airport like KJFK but I will try to increase the virtual memory.
My low fps near big airport or city has nothing do with THE graphical setting. With lower setting I can get a higher fps in rural area or high altitude but for me, 30fps is enough already. The only problem is when approaching big city or airport, no matter how low the setting is, I even tried playing under 720p but the fps is more or less the same. It seems my CPU is
Struggling not my GPU, I only play under 1080p but I can’t even get steady 30 fps in those places.
I started to think maybe I should change my CPU instead of GPU since I only play under 1080p.
