This video compares the three Resolution Settings of Metal Gear Solid 3: Snake Eater (Master Collection) running on the PlayStation 5 Pro.
When the game first launched, it was only available in Original Mode. An Adjusted Mode, which runs at a higher resolution, was later patched into the software.
The High Resolution Mode, which requires a download of the High Resolution Texture Pack, was added in the final update.
All three settings target 60 frames per second.
You can find the comparison between all three Resolution Settings in the video below:
