I have the same rig setup and the same performance issues. Tangled shores 45fps Switching to multi threaded = 1 improves performance but gives lots of flickering artifacts I notice that all across the game GPU usage is low on 1080p, around ~30-80%, regardless of video settings. I also experience micro stuttering where the game freezes for half a second, and it happens quite often. I've tried all the other solutions provided but nothing helps. All other games run smooth with 95%+ GPU usage and no issues. https://pastebin.com/msaD031N
