Free sync意思

"Free Sync" is a technology developed by AMD (Advanced Micro Devices) for its graphics cards and monitors. It is designed to eliminate screen tearing and stuttering, providing a smoother gaming experience. Screen tearing occurs when the monitor's refresh rate is not synced with the graphics card's frame rate, causing a split screen effect with part of the image from one frame and part from another.

Free Sync works by allowing the monitor to synchronize its refresh rate with the frame rate of the graphics card. This means that the monitor will refresh its image only when the graphics card has finished drawing a new frame, rather than at a fixed rate. This can reduce stuttering and tearing, as the monitor is always displaying a complete frame.

Free Sync is available on a range of AMD graphics cards and monitors that support the technology. It is a competitor to NVIDIA's G-Sync technology, which works in a similar way but is only available on NVIDIA graphics cards and monitors that have been certified by NVIDIA.
