As Fast As Possible

NVIDIA Fast Sync and AMD Enhanced Sync are alternatives to V-SYNC. Both Fast Sync and Enhanced Sync allow for uncapped frame rate without screen tearing. Furthermore, these two technologies introduce significantly less input lag than VSync.

Gaming with V-SYNC disabled can cause awful screen tearing. But then, enabling it introduces additional input lag and if your GPU cannot keep up with your display, you get screen stuttering. So, what other options are there?

If you have a gaming monitor with a variable refresh rate technology such as FreeSync or G-SYNC and a compatible graphics card, you can get rid of both screen tearing and stuttering at minimal input lag cost.

Alternatively, you can use NVIDIA’s Fast Sync or AMD’s Enhanced Sync technologies which are basically improved versions of VSync.

In short, Fast Sync eliminates screen tearing when your FPS (Frames Per Second) rate exceeds your monitor’s maximum refresh rate. This increases input lag, but not nearly as much as V-Sync does.

Most gamers find that your frame rate should be at least twice the monitor’s refresh rate (the higher the better) in order for Fast Sync to work best.

Opinions differ on whether Fast Sync should be used if your frame rate is lower than the monitor’s refresh rate as well as if it should be used simultaneously with G-SYNC.

Furthermore, Fast Sync is known to introduces micro stuttering in certain games. In the end, it’s best to try different options for yourself.

How To Enable NVIDIA Fast Sync?

If your graphics card supports Fast Sync, you can enable it in NVIDIA drivers settings. Under ‘Manage3D settings’ go to ‘Vertical Sync’ and set it to ‘Fast’. You should also disable VSync in the video games’ settings.

AMD Enhanced Sync

If you have an AMD graphics card series RX 400, RX 500, or RX Vega, you will find the Enhanced Sync option which basically does the same thing as Fast Sync.

When your FPS goes over the max refresh rate, there will be no screen tearing while the input lag cost will be tolerable as opposed to that of VSync.

In case your FPS dips below, you will experience screen tearing instead of stuttering which is a welcome trade-off.

How To Enable AMD Enhanced Sync?

Under the ‘Gaming’ section of the AMD drivers, go to ‘Global Graphics’ and under ‘Wait for Vertical Refresh’, select Enhanced Sync. You will need at least version 17.7.2  of your AMD Radeon drivers.
