Dishonored 2 is an honorable mess on the PC, needing an NVIDIA GeForce GTX 1070 to barely handle 1080p 60FPS on very low graphics settings.
Dan Sebestyen posted on Twitter saying: "My build GTX 1070, i5 4690K, 16 gig of RAM. At 1080p and 1440p on "Very Low" i get drops to 40 fps in Karnaca". Pretty crappy performance for a high-end graphics card, and very low settings - not being able to hit 60FPS consistently in Dishonored 2? Pathetic.
Dishonored 2's Game Director Harvey Smith said yesterday he was "distressed" over the PC version of the game, saying that it wasn't a port from the consoles. He said that the performance issues aren't related just to graphics, so the issues are much deeper it seems.
