Ground Zeroes shares a lot of issues with The Phantom Pain, they will be covered in that section. Below are a few fixed issues that are specific to Ground Zeroes.
When borderless windowed mode is enabled, the game sets the HWND_TOPMOST flag using SetWindowPos. This forces the window to always stay on top when attempting to ALT+TAB, making the borderless mode less than useful.
MGSVFix removes this flag, ensuring borderless mode behaves as expected.
MGSVFix includes an option to unlock the framerate. This replicates the effect of modifying TPP_GRAPHICS_CONFIG and setting framerate_control to Variable.
While this works well in The Phantom Pain, it introduces physics issues in Ground Zeroes.
At higher framerates (above ~75 FPS), throwables like magazines or grenades freeze in mid-air, as shown in this clip:
Broken.throwable.physics.mp4
MGSVFix corrects this issue, allowing throwables to work properly regardless of framerate.

Each issue listed below is addressed by MGSVFix.
Both The Phantom Pain and Ground Zeroes only support resolutions that are 16:9 or 16:10. MGSVFix removes this restriction and allows the game to display all available resolutions.
Depth of field is exaggerated at ultrawide resolutions. This can be a little hard to see in a static comparison, and is much easier to see in motion.
At ultrawide resolutions lens flares are exaggerated and over-sized.
This is especially noticable in the opening of Ground Zeroes.
Several overlays, such as the one shown when using the sonar, are scaled incorrectly.
Markers that show up after using the sonar are misaligned and incorrectly placed.
When readying a throwable, the destination marker is scaled incorrectly.
Markers are misaligned and incorrectly placed.
When using scopes the frame does not span the screen. MGSVFix partially addresses this issue by stretching the frame to span the screen.
Several menu backgrounds do not span to fill the screen.
While FMV sections in The Phantom Pain are pretty rare, they display incorrectly at ultrawide resolutions. The video itself is stretched to span the screen and a 16:9 video frame is then drawn over the top.
