# **Nvidia’s “Zorah” Tech Demo Revamped to Highlight More RTX Technologies with the RTX 5090**
At the close of January, just ahead of the eagerly awaited launch of the **RTX 5090** and **RTX 5080**, Nvidia introduced a fresh **tech demo** named **”Zorah.”** This demo aimed to showcase the **”future of rendering,”** pushing the limits of real-time graphics and highlighting the latest developments in **RTX technology**.
## **A New Standard in Real-Time Rendering**
The initial **Zorah** demo was already a striking exhibition of Nvidia’s rendering prowess. According to the company, the demo managed to process:
– **Half a billion triangles per scene**
– **30,000 unique materials**
– **2,000 particle lights**
– **1,500 textures**
These components worked together to create an **atmospheric lighting system** that animated the demo’s setting. Despite the heavy computational requirements, **DLSS 4 with Multi Frame Generation** provided a seamless frame rate. Nonetheless, Nvidia has not yet addressed worries over **increased latency** linked to upscaling technologies.
## **Zorah’s Latest Update: Testing the RTX 5090 to Its Limits**
Nvidia has persistently refined the **Zorah** tech demo, releasing a new update that fully utilizes the capabilities of the **RTX 5090**. The recent version emphasizes the prospects of **neural rendering** and **full ray tracing,** establishing a new benchmark for real-time graphics.
### **Notable Improvements in the Updated Zorah Demo**
– **Intricate environments** featuring complex geometry and sophisticated lighting, rendered in real-time on an **RTX 5090**.
– **ReSTIR Path Tracing** and **ReSTIR Direct Illumination,** which improve lighting computations for more lifelike reflections and shadows.
– **RTX Mega Geometry,** a technology previously showcased in **Alan Wake 2,** is now employed to manage substantial geometric complexity.
To assist users in grasping these state-of-the-art technologies, here’s a simplified overview:

## **Glossary of Nvidia RTX Technologies**
### **Neural Rendering**
Neural rendering employs **artificial neural networks** to enhance graphics rendering. In contrast to conventional methods, this technique boosts **performance, image quality, and interactivity** by utilizing **RTX Neural Shaders.** These shaders enable small neural networks to refine textures, materials, lighting, and volumetric effects.
### **ReSTIR Path Tracing**
**ReSTIR GI (Global Illumination)** is a **path-tracing algorithm** crafted for **indirect lighting**—light that reflects off surfaces. This method enhances lighting realism by **resampling indirect light paths** over time and across multiple pixels.
### **ReSTIR Direct Illumination**
**RTX Direct Illumination (RTXDI)** improves **direct lighting** by permitting games to manage **hundreds or even millions of light sources.** This technology removes the previous limitation of allowing only a handful of selected light sources to cast shadows.
### **RTX Mega Geometry**
This technology accelerates **ray tracing for intricate geometries,** enabling a notably higher count of **triangles per scene.** It was first unveiled in **Alan Wake 2** and is now being made available for wider application.
