In a nut shell, since the game update, Exiles does not play smooth. With constant micro lags, which is weird for single player, but that is the best way I can describe it.
My PC has an I9 cpu, 32 ram, with a Gforce GTX 3080
Same here. I tested video settings and the lag/stuttering is the same in low vs. ultra settings. These issues get a lot worse if you are in a well developed base with lots of stuff in it.
