Nvidia’s first alternative to V-Sync was Adaptive VSync. V-Sync forces your GPU to hold frames it has already rendered, which causes a slight delay between what’s happening in the game and what you see on screen. That solves the screen tearing problem, but it introduces another: Input lag. This software-based feature essentially forces your GPU to hold frames in its buffer until your monitor is ready to refresh. The problem is that the buffer and your monitor’s refresh rate may get out of sync, causing a nasty line of two frames stitched together. To keep things moving smoothly, your GPU stores upcoming frames in a buffer. Similarly, your monitor refreshes a certain number of times each second, clearing the previous image for the new frames your GPU is rendering.
Your GPU renders a number of frames each second, and put together, those frames give the impression of smooth motion. G-Sync solves screen tearing mainly, synchronizing your monitor’s refresh rate with the frames your GPU is pushing out each second. G-Sync is Nvidia’s hardware-based monitor syncing technology. With a G-Sync monitor, you’ll notice smoother motion while gaming, even at high refresh rates. In short, G-Sync is a hardware-based adaptive refresh technology that helps prevent screen tearing and stuttering. on-premise hosted service upon request onlyĪndroid, Linux, Windows, MacOS, any POSIX-system

While there are more and more cloud-based Firebase alternatives springing up nearly daily (e.g.
But what options do Mobile and IoT developers working on the edge have for out-of-the-box Data Sync solutions? Very few. Therefore, we’ve recently taken a comprehensive look at mobile database and edge database offerings on the market. With a huge shift happening in computing from the cloud to the edge, offline-first approaches and Edge Computing are getting more and more important.
However, Firebase is purely cloud based and offers no support for local data storage ( as in “data persistence above caching”) and therefore offline usage. One of the most well-known Data Sync solutions is Firebase.
