AMD released GI-1.2, an enhanced real-time Global Illumination solution that introduces multibounce rendering to capture additional light bounces through a two-level hash grid cache system. The update addresses the previous version's limitation where scenes appeared darker than path-traced references by extending ray paths from first-bounce cells to create second-bounce cells, significantly improving reflections and overall lighting accuracy. GI-1.2 is available in AMD Capsaicin Framework v1.3, which also adds HDR display support, DPI awareness, and AMD FidelityFX Super Resolution integration including FSR 4 for RDNA 4 GPUs.
