Description

Use half precision floats where possible in shaders. Shaders that are heavy on bandwidth and arithmetic but don’t require super‑high precision. All modern GPUs support half floats, even GTX 660.

Potential candidates: Bloom, Blur, AO, SSR, etc.

Research direction

Begin by locating the shader sources for the listed Bloom, Blur, AO, and SSR passes. Review which calculations can use half precision without requiring high precision, then verify that the selected passes retain expected visual output and improve bandwidth or arithmetic cost.
