NukeMark

NukeMark is a professional GPU benchmark and stress test built in Unreal Engine 5.7, designed to answer:

How far can your hardware go before it reaches its limit?

Unlike traditional benchmarks that simulate typical gaming workloads, NukeMark is intentionally engineered to exceed the performance budgets of modern games. Every scene is built to overload today’s fastest GPUs, creating one of the most demanding real-time rendering workloads available in a commercial benchmark.

If your system remains stable in NukeMark, you’ll know it has performance headroom everywhere else.

Best-in-Class Benchmarking

Benchmark more than just your framerate.

NukeMark measures your hardware using three independent scores:

• Benchmark (Stress) Score  your primary performance result, ranked on leaderboards.

• Stability Score evaluates how consistently your system performs under sustained load.

• Hardware Score provides additional context about your system’s capabilities.

Your Stress Score stands on its own, while Stability and Hardware Scores help explain the result without influencing your ranking.

Built on Unreal Engine 5.7

NukeMark makes use of bleeding-edge rendering technology that goes beyond what’s available in commercial games.

Every benchmark simultaneously drives Unreal Engine 5.7’s most demanding technologies:

• Nanite virtualized geometry with extreme polygon density

• MegaLights renders hundreds of shadow-casting lights simultaneously

• Lumen Hardware Ray Tracing for global illumination and reflections/refractions

• 8K Virtual Textures streamed across highly detailed environments

NukeMark’s benchmark scenes each target a different performance bottleneck.

Emberhold

Emberhold is designed to overwhelm lighting and shadow performance.

Featuring hundreds of shadow-casting lights, dense custom environments, hardware ray tracing, and extreme geometric complexity, it pushes Unreal Engine’s rendering systems beyond conventional performance budgets.

Even an RTX 5090 sustains only approximately 15–20 FPS at native resolution.

Pandora

Pandora shifts the challenge from raw rendering performance to memory capacity.

Built around massive environments, extensive Megascans assets, and enormous custom content, it creates an exceptionally demanding VRAM workload.

At 4K, Pandora can consume 12–15 GB of VRAM or more, revealing memory limitations long before they become apparent in typical games.

Whether you’re:

• Building a gaming PC

• Testing an overclock

• Stress testing new hardware

• Comparing GPUs

NukeMark provides a demanding, repeatable benchmark designed to reveal what your hardware is truly capable of.
