If you're going for upscaled at the best it can be, then on a 1080p screen going above 4x IR is kinda useless because your monitor can't display anything higher. Then start applying AA/AF until the games run slowly.
Do not open the Graphics settings while the game is running, since it will overwrite the per-game defaults that make the games run properly. Make a change, run the game and check how it plays, close the game, make a change, restart. (that's how I do it anyways)
Since you have Nvidia, using OpenGL is probably the best for speed and stability.
