I have:
Ryzen 3900x @ 4.25
32gb Trident Z Neo 3600mhz
970 Evo 512GB that MSFS is installed on
GTX 1080 +169 core +512 mem
Thing is my FPS is fine, but I still get stutters even at 60fps that make it unplayable. Oddly enough it happened very recently. There were stutters before but they weren’t bad enough to really bother me, but a couple days ago I went to a 24" monitor and just figured that was making the stutters worse as I went from 1440x900 to 1920x1080, so I went back to my 19" and it didn’t change a thing.
There is definitely a big issue with the sim that doesn’t have anything to do with the graphics settings as there are terrible stutters even when dropping way down to medium (i’ve ran on ultra since release). Always main thread limited too, but nothing new there.
