in the last few years best gaming monitor (opens in new tab) Enjoying something of a Renaissance. Adaptive-Sync technology Nvidia G-Sync (opens in new tab) When AMD FreeSync (opens in new tab)In the 1990s, the only thing performance-seeking gamers could hope for was higher resolutions or refresh rates above 60 Hz. We are updating our technology. Which Adaptive-Sync technology reigns supreme in the battle between FreeSync and G-Sync in this era of gaming displays?

There are also next-gen graphics cards on the horizon, such as the Nvidia GeForce RTX 4090 and Ada Lovelace GPUs with DLSS 3 technology that could double framerates even at 4K. AMD’s RDNA 3 and Radeon RX 7000 series GPUs are also coming soon, which should boost performance and make higher quality displays more convenient.

For starters, Adaptive-Sync means that your monitor’s refresh cycle is synchronized with the refresh rate of the connected PC. graphics card (opens in new tab) Render each frame of the video, even if the rate changes. The game renders each frame in sequence, but the rate varies greatly depending on the complexity of the scene being rendered. If your monitor has a fixed refresh rate, the screen refreshes at a certain interval. For example, 60 times per second on a 60 Hz display. What if the new frame is ready before the scheduled update?

You have several options. One is to make the GPU and monitor wait to send new frames to the display. This can increase system latency and make games less responsive. Another option is to allow the GPU to send a new frame to the monitor and start drawing to the screen immediately. This is called tearing and the result is shown in the image above.

G-Sync (for Nvidia-based GPUs) and FreeSync (possibly AMD and Intel GPUs) aim to solve the above issues, offering maximum performance, lowest latency and no tearing To do. The GPU sends a “frame ready” signal to the Gsync or FreeSync monitor. The G-Sync or FreeSync monitor draws a new frame and waits for the next “frame ready” signal. This eliminates tearing artifacts.

Today, you can find countless monitors (including non-gaming monitors) boasting flavors of G-Sync, FreeSync, or both. If you haven’t committed to graphics card technology yet, or have the option to use one or the other, you may be wondering which is best for you when considering FreeSync and G-Sync. And if you have the option to use one over the other, does one offer a gaming advantage over the other?
