This video compares the three Original, High Resolution and Max Resolution modes of Metal Gear Solid in the Metal Gear Solid Master Collection Volume 1 release.
When the game first came out on new platforms, only the Original mode was available. The High Resolution and Max Resolution modes were added through post-launch patches.

As a result, the Smoothing feature is turned off for Original mode, but turned on for the High Resolution and Max Resolution modes.
