Overview
- At GDC 2026, Nvidia’s John Spitzer said Blackwell‑era RTX hardware plus DLSS 4.5 and SDK improvements deliver roughly a 10,000x path‑tracing uplift versus Pascal.
- Spitzer projected a million‑fold improvement in a future generation, with coverage suggesting it could arrive in the Rubin timeframe targeted for 2027–2028.
- Nvidia outlined new path‑tracing tech including ReSTIR, RTX Mega Geometry updates, and opacity micromaps to improve reflections, global illumination, and dense foliage rendering.
- DLSS 4.5’s MFG 6X frame‑generation mode and a dynamic switching option are slated to roll out later this month.
- Nvidia is collaborating with Microsoft to bring Advanced Shader Delivery to GeForce RTX later this year to curb shader compilation stutter, with AMD, Intel, and Qualcomm also backing the effort.
