Currently there are two options to play video games: Use vsync, which causes frame rate stuttering if the game renders more slowly than the monitor's refresh rate, or not use vsync, which causes image tearing (unless the game can render at exactly the same framerate as the monitor's refresh rate; which is practically impossible without vsync.) Frame stuttering happens when the game is constantly jumping between eg. 60Hz and 30Hz frame rate, due to the game actually rendering at something in-between those two, and syncing with the monitor's 60Hz refresh rate. Same thing happens, but even worse, if the rendering speed drops below 30Hz. On the other hand, frame tearing causes annoying horizontal artifacts when the image updates while the screen is refreshing. The position of the tear tends to jump randomly on the screen on each refresh, worsening the effect. (And if the game is actually rendering faster than the monitor's refresh rate, you'll get multiple tears on ...
