Viewerframe Mode — Exclusive //top\\

Software often utilizes "exclusive" modes to optimize hardware resources. When a viewer frame—the window through which a user observes data or a game world—is set to exclusive mode, the operating system bypasses certain background processes. This reduces input lag and increases frame rates, as the GPU can focus entirely on rendering that specific window without the overhead of managing a desktop environment or overlapping applications. 2.
