What Causes Frametime Inconsistency?

Spikes in frametime (above the yellow reference line) occur when shader compilation, asset streaming, or background OS processes delay frame presentation to the GPU scanout buffer. Capping FPS 3 below your monitor's refresh rate keeps the frame within the VRR window, preventing V-Sync buffer backpressure latency.
