Scanline Sync is best used to compensate for the lack of FreeSync and G-Sync, but it comes with a catch, too: high GPU utilization (~80%+) under Scanline Sync can introduce major screen tearing to an image. In this case, Scanline Sync’s job is already being done by the monitor (and compatible GPU), so it’s unneeded. The main way to decide between the two features is to take a look at your existing hardware.įPS caps will work on the most systems with the fewest issues and is preferred to Scanline Sync if you already have a FreeSync or G-Sync monitor. While RivaTuner offers both FPS capping and Scanline Sync, you can’t actually use both simultaneously. Should I use an FPS cap or Scanline Sync? With the right adjustments, this scanline can be moved nearly offscreen and provide a tear-free, lag-free alternative to V-Sync. Unlike other techniques, which work with complete frames as much as possible, Scanline Sync actually allows you to choose a specific scanline, one where screen tearing is near-guaranteed but contained.

Where Scanline Sync differs from other V-Sync alternatives is actually hinted at in its name. your living room TV, should you want to game on it without horrific screen tearing or input lag). Scanline Sync is particularly ideal for displays that don’t have FreeSync or G-Sync (e.g. FreeSync and G-Sync are both hardware-enabled features, though, whereas Scanline Sync is used in software to achieve a similar effect. Scanline Sync, like FreeSync and G-Sync, is another technology that looks to replace the V-Sync standard. If the game you’re playing offers an FPS cap, chances are high that you’ll want to use that cap instead of RivaTuner’s, but if you want to learn how to use RivaTuner’s for universal application, keep reading. Using an FPS cap, you can set your in-game framerate to just at or just under your screen refresh rate. Both of these can be visually disorienting and a competitive disadvantage, but the seemingly only way to fix it in most games is to enable some form of V-Sync, which is much more visually consistent but adds a lot more input latency. FPS in this context refers to Frames Per Second, and on PCs where you have an FPS exceeding your refresh rate (such as 100 FPS on a 60 HZ panel), you’re much more prone to screen tearing and highly-variable FPS.
