VRR vs. V-Sync: What's the Difference?

While both Variable Refresh Rate (VRR) and Vertical Synchronization (V-Sync) aim to improve the visual quality of games by addressing screen tearing, they operate on fundamentally different principles and offer distinct advantages and disadvantages.

V-Sync is the older technology of the two, having been a staple in gaming graphics settings for many years. It works by forcing the GPU to wait until the monitor has finished its refresh cycle before sending a new frame. This synchronization effectively eliminates screen tearing but can introduce new problems:

1. Input Lag: V-Sync can significantly increase input lag, as the GPU may need to hold frames for longer periods to match the monitor's fixed refresh rate.
2. Stuttering: When frame rates drop below the monitor's refresh rate, V-Sync can cause noticeable stuttering as it waits for the next refresh cycle.
3. Performance Impact: V-Sync can sometimes reduce overall performance, especially in scenarios where the GPU is struggling to maintain frame rates at the monitor's refresh rate.
   

On the other hand, VRR technology takes a more dynamic approach:

• Adaptive Synchronization: Instead of forcing the GPU to wait, VRR allows the monitor to adapt its refresh rate to match the GPU's frame output in real-time.
• Reduced Input Lag: By eliminating the need for the GPU to hold frames, VRR significantly reduces input lag compared to V-Sync.
• Smoother Low Framerate Performance: Many VRR implementations include Low Framerate Compensation (LFC), which helps maintain smoothness even when frame rates drop below the monitor's minimum refresh rate.
• Minimal Performance Impact: VRR typically has little to no impact on overall system performance.

The advantages of VRR over V-Sync are clear in most gaming scenarios. However, there are still situations where V-Sync might be preferable:

1. Older Games: Some older titles may not play well with VRR technology and might benefit from traditional V-Sync.
2. Specific Visual Artifacts: In rare cases, VRR can introduce its own visual artifacts that some users find distracting. In these instances, V-Sync might provide a more stable image.
3. Non-Gaming Applications: For tasks that don't require low input lag, such as video playback, V-Sync can still be a viable option.
