If your profiler says “drawing is expensive” and you still cannot see why, you are debugging blind. Frame Debugger is where you stop guessing and inspect the exact draw-event chain behind the bottleneck.
This module teaches the practical sequence: use profiler for hotspot direction, Render Graph view for high-level flow, then Frame Debugger for per-draw-call evidence. You learn to inspect render targets, channels, levels, and pass behavior without drowning in noise.
The evidence frame is actionable inspection: isolate the relevant draw event, verify what each pass writes, and correlate suspicious output with concrete pipeline stages, including complex HDRP/deferred paths where pass volume can hide the real issue.
Your next dev step: capture one problematic frame, trace the suspicious draw call through Frame Debugger and Render Graph, then compare expected vs actual output before touching shader or content code.
CEO/Producer translation: faster root-cause isolation cuts optimization cycle time and lowers regression risk in rendering-heavy features.
