Titan X. I have a 780 Ti @ 1215MHz and a 5930K and all settings are at Very High minus Grass which is on High and reflection MSAA @ 2x. All advanced graphics are disabled, FXAA only. That is enough for a locked 60FPS 90% of the time at 1200p. There are only 3 options that go to Ultra, Grass being one of them. I find it hilarious that 2880 Kepler cores can't run very high quality foliage. And be honest, a lot of the assets and world detail look vastly better than the original console release but are still old-gen. If you are looking for Crysis 3 level of detail it ain't here.
