If you’re willing to buy a new monitor, variable refresh rate is one of the best upgrades features you can get. Known as G-Sync on the Nvidia side and FreeSync on the AMD side, they reduce screen tearing and sync your monitor’s refresh rate with your video card’s output for a smoother experience. While FreeSync are easy to come by and affordable, monitors with NVIDIA’s G-Sync are always more expensive, leaving budget-minded GTX users out in the cold, until just recently.
This year at CES, Nvidia announced that it was bringing G-Sync compatibility to some FreeSync monitors with a new driver update. They’ve officially validated 50 monitors as “G-Sync compatible,” but anyone can enable variable refresh rate (VRR) if they have the latest Nvidia drivers and a FreeSync-enabled display—and many have found certain uncertified monitors to work just fine.
