How to download the NVIDIA Zorah sample
- Open NVIDIA’s official RTX Kit page. Use NVIDIA’s first-party page rather than a third-party mirror, because NVIDIA has previously changed the availability of an earlier Zorah archive.
- Find the control labeled Download Zorah Sample.
- Download the current archive,
ZorahSample_UE5_Source_1.1.0.7z. - Before extracting it, confirm that the download came from an NVIDIA domain and that the filename matches the current listing.
- Extract the archive with a 7-Zip-compatible utility and read the included documentation before attempting to launch or build the sample.
- Use the archive’s documentation as the authority for the current GPU, driver, operating-system, Unreal Engine, build, and storage requirements.
The official RTX Kit page is the safest source for the sample. Avoid treating an old forum attachment, repost, or mirror as equivalent to the current NVIDIA release.
What you are actually downloading
Zorah is a source/sample archive created with Unreal Engine 5 and distributed through NVIDIA’s RTX Kit developer ecosystem. It is intended to demonstrate rendering technology, so the download experience is different from installing a normal commercial game through Steam, the Epic Games Store, or another game launcher.
#1 Best Overall
- Powered by the NVIDIA Blackwell architecture and DLSS 4 OC mode: 2640MHz/Default mode: 2610MHz (Boost Clock)
- Military-grade components deliver rock-solid power and longer lifespan for ultimate durability

The RTX Kit page presents Zorah alongside developer technologies for neural shaders, RTX Mega Geometry, dynamic illumination, path tracing, denoising, and related rendering systems. The archive may therefore be most useful to developers, technical artists, graphics enthusiasts, and PC users who want to inspect NVIDIA’s showcase rather than play a conventional game campaign.
What Zorah showcases
NVIDIA’s GDC 2025 material presents Zorah as a Blackwell launch demonstration built around next-generation real-time rendering. Its feature set is broad, and the technologies solve different problems rather than representing interchangeable names for the same effect.
| Technology | What it contributes |
|---|---|
| Path tracing | Simulates light transport through a unified ray-traced rendering approach. It can produce more coherent lighting, reflections, shadows, and indirect illumination, but it is substantially more demanding than conventional raster rendering. |
| RTX Mega Geometry | Addresses the acceleration-structure cost of scenes containing extremely detailed and changing geometry. NVIDIA describes a cluster-based approach intended to make the building and updating of ray-tracing structures more practical. |
| ReSTIR Path Tracing | Improves the selection and reuse of lighting samples for path-traced images, helping the renderer spend limited ray and sample budgets more effectively. |
| ReSTIR Direct Illumination | Targets direct-light sampling specifically, helping scenes with many potential light sources use available samples more efficiently. |
| RTX Hair | Supports the rendering of detailed hair and related strand-based geometry with ray-tracing hardware and software techniques. |
| DLSS-related rendering | NVIDIA’s presentation associates the demo with DLSS image-quality and frame-generation techniques. The exact available features and settings depend on the build, hardware, drivers, and documentation included with the current sample. |
Why Mega Geometry matters
Highly detailed Unreal Engine scenes create a difficult ray-tracing problem: the renderer must maintain acceleration structures that let rays find relevant geometry quickly. Ordinary updates become increasingly expensive as geometry becomes more complex or changes frequently.

NVIDIA’s Mega Geometry documentation describes cluster-level acceleration structures and partitioned top-level acceleration structures intended to reduce that update cost. NVIDIA says the approach can enable up to 100 times more ray-traced triangles in heavily ray-traced scenes. That is a claim about the technology’s potential in the stated context, not a promised performance multiplier for every Zorah installation or every GPU.
Does Zorah require an RTX 5090?
There is no confirmed basis for stating that an RTX 5090 is mandatory. Zorah is clearly designed as a Blackwell showcase, and Blackwell is the most natural platform for experiencing the intended feature set. However, NVIDIA’s RTX Kit FAQ says that individual components have their own hardware requirements and that the broader suite is designed to work across a range of ray-tracing-capable hardware.
NVIDIA’s Blackwell architecture documentation describes Mega Geometry support across NVIDIA RTX GPUs beginning with Turing, while also explaining that Blackwell adds dedicated RT-core enhancements for the technology. That does not mean every Zorah feature, configuration, or performance level is available on every RTX generation.
Until the current archive documentation provides a complete requirements table, do not treat any of the following as confirmed facts:

The most appropriate consumer GPU match
If you want hardware that most directly matches Zorah’s Blackwell showcase, the GeForce RTX 5090 is the obvious consumer reference point. NVIDIA lists it as a Blackwell GPU with 32 GB of GDDR7 memory and fourth-generation ray-tracing cores. Its specifications also include support for path tracing and DLSS features, along with a 1,000-watt recommended system power specification for the reference configuration.
That makes the RTX 5090 a sensible hardware consideration for users building a system around demanding path-traced demos. It is not, however, a reason to purchase a new graphics card merely to download Zorah. Check the sample’s included requirements first, and remember that the demo is a technology showcase rather than a game with a guaranteed performance target.
What to check before launching the sample
Because NVIDIA’s accessible RTX Kit listing does not expose a complete Zorah-specific requirements matrix, use this checklist after extraction:
- GPU: Identify which RTX generations and features the current build supports.
- Driver: Check whether the documentation specifies a minimum or recommended NVIDIA driver.
- Operating system: Confirm the supported Windows version or any other platform limitation in the included notes.
- Video memory: Look for a stated VRAM requirement, especially if the sample includes high-detail assets.
- System memory and storage: Allow room for the downloaded archive, extracted files, shader caches, generated data, and any build output. No precise archive-size claim should be made until the current download metadata confirms it.
- Engine/build instructions: Follow NVIDIA’s included steps instead of assuming the archive behaves like a packaged game executable.
- Feature support: Confirm whether path tracing, Mega Geometry, ReSTIR, RTX Hair, and DLSS-related options are all enabled in your particular configuration.
Developer notes: RTX Kit and NvRTX
Developers who want to investigate or extend the technology should distinguish the downloadable Zorah sample from NVIDIA’s modified Unreal Engine branches. NVIDIA provides an RTX branch of Unreal Engine known as NvRTX, with branches for several Unreal Engine versions.
NVIDIA describes an experimental branch containing RTX Mega Geometry support for real-time path tracing of Nanite geometry. The branch is not fully validated and may contain limitations or regressions, so NVIDIA does not position it as a dependable foundation for a shipping game without additional testing.
Access to the relevant Unreal branches requires linking an Unreal Engine account with a GitHub account and completing the associated invitation or authorization process. That developer workflow is not necessary simply to obtain the Zorah sample from RTX Kit, but it may matter if you intend to inspect engine-level integrations or modify the rendering path.

RTX Kit is an ecosystem of separate technologies. A GPU that supports one component does not automatically guarantee support for every SDK or every Zorah feature. Check the component-specific notes.
Interpreting the demo as a benchmark
Zorah demonstrates a collection of rendering techniques, but it should not be used as a standardized benchmark unless NVIDIA publishes a defined test procedure. Results can vary with resolution, quality settings, DLSS mode, frame generation, driver version, scene state, and background workload.
Download verdict
