Nvidia G-Sync
G-Sync is a proprietary adaptive sync technology developed by Nvidia aimed primarily to eliminate screen tearing and the need for software deterrents such as Vsync.[1] G-Sync eliminates screen tearing by forcing a video display to adapt to the framerate of the outputting device rather than the other way around, which could traditionally be refreshed halfway through the process of a frame being output by the device, resulting in two or more frames being shown at once.[2] In order for a device to use G-Sync, it must contain a proprietary G-Sync module sold by Nvidia.
Criticism
G-Sync faces some criticism due to its proprietary and exclusionary nature, due to it still being pushed when free alternatives such as AMD's FreeSync already exist as a VESA standard under DisplayPort. While FreeSync has been adopted as a component of DisplayPort 1.2a, G-Sync requires an Nvidia-made module to be added to the display in order for it to function properly with select Nvidia GeForce graphics cards.[3]
GPU and system requirements
- GPU: G-SYNC features require an NVIDIA GeForce GTX 650Ti BOOST GPU or higher.
- DRIVER: R340.52 or higher.
- Operating System: Windows 7, 8, 8.1 and 10, and Linux
- System Requirement: Must support DisplayPort 1.2 directly from the GPU.[4]

G-Sync Notebook
Nvidia announced that G-sync will be available to notebook manufacturers and that in this case, it would not require a special module since the GPU is directly connected to the display without a scaler in between. According to Nvidia, fine tuning is still possible given the fact that all notebooks of the same model will have the same LCD panel, variable overdrive will be calculated by a shader running on the GPU, and a form of frame collision avoidance will also be implemented.[8]
