Description

[video] Optimizing Individual Draw Calls - Game Optimization - Episode 9 is an approximately 52-minute YouTube lesson by Ben Cloward in his Game Performance Optimization series. It focuses on inspecting costly individual draws after whole-scene feature tuning.

Using PIX captures, it shows how to open opaque draw lists, sort by GPU time, identify meshes from pipeline state, and cut cost in Unity and Unreal scenes. Topics include matching foliage detail distance to pixel-shader fade so vertex work is culled, and comparing before-and-after timings. It continues earlier episodes on PIX analysis and scene-wide settings.

It is for intermediate Unity and Unreal developers who can already capture PIX frames and want a method for hunting expensive meshes beyond global quality toggles.

Access is a free YouTube video with series playlist links in the description and related book recommendations from the creator.

It is useful when post-process and shadow wins are done and remaining frame time is dominated by specific draw calls.
