You don't need delta timing if your game is not going to slow down below the default framerate. If you can be sure its fast enough to never go below 60fps it will be okay using just Flip() at 60hz.
And no integers are not accurate enough to look completely smooth. The use of an integer is actually a way of `rounding` a `real value` and locks it onto a grid of 1x1 pixels, which will cause your objects to jump to the grid location.
