Viewerframe Mode Refresh Work

A ViewerFrame is the final, composited image ready to be sent to a physical display device. It is not a raw frame from a video file, nor is it a back-buffer from a 3D renderer. Instead, it is the frame as seen by the viewer—post-processing, post-scaling, and post-composition.

In multi-monitor setups or complex UI environments (like a video editor or a game engine’s viewport), different "viewers" might have different frames. For example:

In continuous mode, the refresh loop runs as fast as the event queue allows, often exceeding the display’s vertical sync. This causes tearing and unnecessary CPU/GPU load.

To truly optimize the "viewerframe mode refresh work," you must understand the pipeline. Let’s walk through a single cycle.

The goal is minimizing latency while maximizing smoothness. The "ViewerFrame" is the final product of the

The goal is to match the source framerate perfectly.

NVIDIA’s DLSS 3 and AMD’s FSR 3 introduce "fake" frames. The system analyzes two real ViewerFrames and generates an intermediate frame using AI. The refresh work shifts from rendering to inferencing.
