Meh , I ' m getting a supersteady 60 FPS with the DX 11 client windowed fullscreen . Haven ' t really seen it dip below 59 even if I open stongboxes in crowded areas . And I used to get huge stuttering and FPS spiking before , so in my books the 64 bit DX 11 client is the best thing ever . Running with i 76700 k 4 , 5 GHz , AMD R 9 390 8 GB , 16 GB RAM and the game installed on an SSD . <| sep |> Explanation of what happened is in the dman article . Jesus . Do you people always comment your opinions without even reading the article ? ? This guy even went all the way to search for a explanation and didnt even read the article , which has a very thorough and complete explanation even more complete than what was linked here <| sep |> There ' s a command line for that ? Why am I surprised ? TIL
