VSync & Triple Buffering Greyed Out In Game

I have tried every possible fix, but VSync and Triple Buffering are not selectable options within my game. Does anyone know why?

I've done the following things

Graphics Control Panel Settings I confirmed that VSync is forced on at the GPU control panel level. I went to the NVIDIA Control Panel, found the Manage 3D settings section, and set the VSync setting to "On" for this game and global settings.

I switched to the Full-Screen version windowed to see if it would enable it.

Driver Updates Updated all drivers and ensured they are working correctly. 

Uninstalled and Reinstalled the game.

I updated it with a new patch, uninstalled and reinstalled the game, and still had no luck.
