In this case, the Scanline Sync job is already being done by the monitor and the GPU, so it won’t need to be enabled. The main way to decide between the two features is to take a look at your hardware:įPS limits will work on most systems with the least amount of issues, and Scanline Sync is preferred if you already have a FreeSync or G-Sync monitor. While RivaTuner offers FPS limiting with Cap FPS and Scanline Sync, you won’t actually be able to use both simultaneously, so this is something to keep in mind to start with: you have to choose one or the other. When should you use Cap FPS or Scanline Sync?

With the correct settings, this scan line can be practically moved off the screen and provide an alternative without tearing and without the latency of V-Sync. Where Scanline Sync differs from other V-Sync alternatives, it is actually hinted at in its name: Unlike other techniques that work with full frames as much as possible, Scanline Sync allows you to choose a specific scan line, one in the that the tearing of the screen is almost guaranteed and yet contained.
