Understanding Screen Tearing, VRR, and Input Latency for Gamers in Cook Islands
Screen tearing occurs when a GPU delivers frames at a different rate than the monitor's fixed refresh cycle. When a new frame begins writing to the framebuffer mid-refresh, the display shows part of the old frame and part of the new frame simultaneously — creating a visible horizontal split artifact. Variable Refresh Rate (VRR) technologies like NVIDIA G-Sync and AMD FreeSync solve this by allowing the monitor to dynamically adjust its refresh rate to match GPU output.
