What is freesync on nvidia?

FreeSync is an adaptive synchronization technology developed by AMD, which allows a compatible graphics card to synchronize its display output with a compatible monitor's refresh rate. This technology reduces screen tearing and stuttering and provides a more smooth gaming experience.

Initially, FreeSync was designed for AMD graphics cards only, but it is now supported by some Nvidia graphics cards as well. Nvidia added support for FreeSync through a driver update in 2019. However, Nvidia only supports FreeSync on selected monitors that are certified as compatible with their graphics cards.

To use FreeSync on Nvidia graphics cards, you need to have a Geforce GTX 10-series or newer graphics card, and the monitor should be FreeSync compatible and have a DisplayPort interface. Also, you need to enable "G-Sync Compatible" in the Nvidia control panel.

Overall, FreeSync on Nvidia is a great option for those who want to take advantage of adaptive synchronization technology on monitors that are not G-Sync compatible or are looking for an affordable alternative to G-Sync monitors.
