VRRtekniikoita

VRRtekniikoita, or Variable Refresh Rate techniques, are a suite of technologies designed to synchronize the display's refresh rate with the frame rate of a graphics source, such as a video game console or PC. This synchronization aims to eliminate screen tearing, reduce stuttering, and improve overall motion smoothness. Screen tearing occurs when the display refreshes its image mid-frame from the graphics source, resulting in a visible horizontal line where two different frames are displayed simultaneously. Stuttering, on the other hand, can happen when the frame rate drops below the display's fixed refresh rate, causing frames to be held for longer than usual, leading to jerky motion.

The most common VRR technologies include NVIDIA's G-Sync and AMD's FreeSync. Both operate on similar principles but utilize different proprietary hardware and software implementations. G-Sync typically requires a dedicated hardware module within the monitor, while FreeSync is an open standard that can be implemented by monitor manufacturers without licensing fees. The key idea behind these technologies is to allow the monitor to dynamically adjust its refresh rate to match the output of the graphics card. When the graphics card renders a new frame, it signals the monitor to refresh immediately, ensuring that each displayed frame is complete and in sync. This results in a more fluid and responsive visual experience, particularly beneficial in fast-paced gaming where split-second timing is crucial. To utilize VRR, both the display and the graphics source must support compatible VRR technology.
