GPU Budget Investigation: Baseline to Optimized

A budget decision needs more than one number

The test compares a baseline material path with an optimized variant captured at 1920x1080 on the same scene, lighting, and camera path.

GPU frame time8.4 -> 5.7 ms-2.7 ms / -32%

CPU submit time3.1 -> 2.4 ms-0.7 ms / -23%

Peak memory312 -> 246 MB-66 MB / -21%

Draw calls184 -> 126-58 / -32%

Texture samples42 -> 28-14 / -33%

90 Hz budget used74% -> 51%11.3 ms frame budget

Baseline -> optimized values. The arrow direction is consistent across every metric.

Same 1920x1080 capture conditions; lower values are better for this budget review.
Variant	GPU ms	CPU ms	Memory MB	Draw calls	Samples
Baseline	8.4	3.1	312	184	42
Optimized	5.7	2.4	246	126	28

The decision was to keep the optimized path: it recovered GPU and memory headroom without requiring a new material authoring workflow.
