I tried 4k watch dogs with no AA and with 3 titan blacks in sli it is unplayable, stuttering mess even now with all over the place fps, yet if i drop to using 2 blacks it runs much smoother but still not perfect, but playable for sure. The best performance for hardly any stutter and frame drops is with just 1 black. My question being how did you manage 4 titans to run at a consistent type of frame rate in sli. To me the sli profile seems the major issue. If i alter it to another profile it can run at 60fps but the graphics etc flicker and the physics on foliage goes spazzy but it indicates that perhaps a better profile would solve how well it ran.
