I’ve tried every combo possible and right now, I’ve found a no-stutter, smooth-everywhere, 30fps consistant experience. I can fly in and out of airports, taxi around, look around, all now at 1440p, medium settings, clouds on high setting along with a few others with no lag or stutters. MSFS is a weird beast and seems to have a sweet spot the size of the head of a pin based on the CPU/GPU combo. We’ve all seen posts by folks with 3090’s that struggle because of their GPU/CPU combo.
The pure 1080p experience gives me higher frame rates and higher settings but overall not a better experience either visually or game/sim play wise. Visually things look the same but 1440p I can easily read dials and cockpit displays whereas 1080p is fuzzy.
I think that from what I’m seeing here that I’m as good as I can get with what I have.
