Sync to Vblank missing?

So as of late I’ve been having issues with video-tearing on my laptop, and one of the solutions that is supposed to fix it requires the enabling of “Sync to Vblank” found in the Nvidia X Server Settings, under the OpenGL Settings. However, when I navigate there to enable it, its missing, and only “Image Settings” and “Conformant Texture Clamping” are visible. The graphics card that I’m using is a GT 755M, along with the 331.79 driver for it. If anyone can help me with this, please reply when possible.
