Thought so, i've seen a article wich explained that v4 has his own (good) supporting MSAA, FXAA etc. Last couple of days i played arround with internal P3D settings like the Vsync, FPS-limiter and so on. Still haven't figure out what settings is the optimal one for my rig. Think i'll just go to default graphics and work my way up again. Thanks for anwsering!
