What Are G-SYNC And Free-SYNC

G-SYNC is NVIDIA’s proprietary variable refresh rate technology that helps eliminate tearing and stuttering in games. It does this by matching the game’s frame rate to the monitor’s refresh rate (60Hz, 120Hz, 144Hz). G-SYNC can be enabled on monitors with a max of 144 Hz. There are 3 types of G-Sync: G-SYNC Compatible displays which work with all cards; NVIDIA® GeForce® GTX™ GPUs only for FreeSync compatibility; and AMD Radeon ™ RX 400 Series GPUs only. The latter two will require connecting via HDMI or DisplayPort respectively to activate FreeSync or utilize their full potentials.

Some Features of G-SYNC

  • Eliminates screen tearing and minimizes stuttering
  • Synchronizes the refresh rates between the GPU and display, eliminating excess frames
  • Allows users to enjoy games at higher framerates than what their systems normally allow, with no image tearing or artifacts that produce lag and stutter
  • Requires the display technology to support a variable refresh rate, also known as Adaptive-Sync (FreeSync)
  • Allows gamers to plug their displays into any recent NVIDIA GeForce GPU and benefit from G-SYNC without additional hardware or software.

FAQ

Q: What is FreeSync?

A: AMD’s version of the technology is called FreeSync and works with compatible displays connected to any recent AMD Radeon GPU. Like G-SYNC, it eliminates screen tearing and minimizes stuttering as well as input latency by allowing the display to dynamically adapt to the framerate generated by a user’s graphics card.

Q: What platforms does G-SYNC work on?

A: NVIDIA G-Sync is compatible with GeForce GTX 600, GTX 700, and 900 Series desktop GPUs (GTX 650 or higher recommended; GTX 750 Ti or higher recommended for G-Sync Surround configurations), as well as select notebook GPUs.

Q: Can I enable G-SYNC if my Radeon GPU is installed in my system?

A: No. G-SYNC requires a compatible NVIDIA GPU to function, as well as a display that supports Adaptive-Sync (FreeSync). You can learn more about FreeSync here.

Q: Does G-SYNC work with games that support 144Hz even if I don’t have a 144Hz monitor?

A: Yes. G-SYNC will adapt the framerate to your monitor’s native refresh rate by changing its refresh rate to equal the framerate generated by your GPU.

Q: I have a 4K display and a powerful enough NVIDIA graphics card that can drive games at more than 60 FPS on high settings @4K resolution. Can I enable G-SYNC with my setup?

A: Yes. If your monitor supports 4K resolution at a framerate exceeding 60Hz, you can take advantage of G-SYNC in games that support it.

Q: Why is there still tearing in some games when G-SYNC is enabled?

A: There are many variables that impact whether or not G-SYNC eliminates tearing. Please see the list of compatible and supported games for more information.

Q: I have a 120Hz monitor, but my game is locked to 60 FPS. How do I get around this?

A: Most games require an unlocked framerate to take advantage of a higher refresh rate. To get around this limitation, you can use a program such as Rivatuner Statistics Server to unlock the framerate in-game.

Q: How do I know if my monitor supports G-SYNC?

A: NVIDIA G-SYNC is only supported through DisplayPort on monitors that support it. If your monitor has a DisplayPort and is listed here, then it supports G-SYNC.
