Hello Ralf! I am currently playing this game and I followed the tips you gave, so I think there’s something wrong with Direct X 11 in game AND THE LATEST VERSION OF vORPX. I am in the Sarif HQ if I turn off direct X 11 my frame rate is perfect, if I turn on direct X 11 I end up with 4-6 FPS, I have a GTX 1080 I am running 1280×1023 4:3 I tried without antialiasing. Could you take a look? Thx!
