So as your FPS fluctuates from say 45fps to 60, it'll stay smooth the whole range through, as the monitor will adaptively, natively, support all of those framerates, instead of just trying to make everything work at 60.
This reduces latency, and also means that you won't stutter in between 60 and 30 fps. In doing so, it adds latency and can only run at either 60fps or 30fps, because your monitor is dictating what your video card will do.įreesync and G Sync flip that around, and have your video card tell your monitor what to do, and eliminates tearing by making the monitor display whatever the video card is ready for. So with Vsync, essentially, your card slows itself down in order to avoid going faster than your monitor, which is always 60hz/fps. To explain why it's important, we have to explain why Vsync is deficient. Freesync and GSync both provide an alternative to V Sync.
