I am not sure if its just me but my performance is terrible, the worse performance I had from an AC game, the FPS goes from 100 to 25 to 50 to 30 its all over the place, I ran the benchmark and the GPU usage was 67% and the CPU was 50% but I noticed its maxing out the first core, so I disabled that but then it maxed out another, shocking performance....

well actually I have

i7 4970k 4.6k on all cores
16GB DDR3
GTX 1080Ti
Playing on 1440p full detail everything on ultra except FOV is on default setting.
Game never drops under 60 FPS ever (adaptive AA is off & AA is set to highest). It plays between 60-100 depending on the complexity of the scene.

But my CPU usage is unbeliavable... All 8 threads are between %80-100 at all times. GPU usage drops to %70s when all threads hit almost %100 at the same time (it happens rarely). Even under those conditions I never drop under 60 FPS although I have never seen a single game putting so much pressure on CPU.

I guess your problem is with the CPU, game is extremely CPU demanding, and it should use all cores of your CPU but for some reason it seems it doesnt

same, my 6700k is getting used at 100% 1080ti doesn't hit 80% usage so deffo something off there, a game shouldn't be taxing all 8 cores this much

UPDATE 27/10/17: I found the problem, its linked to SLI both cards showing 30% usage, even if I go into the NVIDIA panel and select SINGLE GPU it still tanks the game. So I disabled SLI and now the FPS at MAX settings is 71FPS. If others are having a similar issue try totally disabling SLI.
