## Key points

- Nukemark overwhelmed an RTX 4070 Super at all tested settings.
- The benchmark is intentionally harsher than modern games.
- DLSS produced unexpectedly worse results in this early-access test.

## Summary

PC Gamer tested Nukemark, an early-access Unreal Engine 5.7 benchmarking tool designed to push modern graphics cards beyond typical gaming workloads. On the writer’s RTX 4070 Super gaming PC, both tests ran at very low frame rates even at 1080p and 1440p, illustrating how demanding the software is rather than indicating ordinary games will perform similarly.

The system used an AMD Ryzen 7 7800X3D, 32GB DDR5 memory and an RTX 4070 Super. Its best result was 23fps in the Pandora test at 1080p, while 1440p results fell to 12–13fps; enabling DLSS unexpectedly reduced performance to 5–6fps at 1440p. Nukemark uses Nanite, MegaLights, hardware ray tracing and virtual textures up to 8K, and its developer says even an RTX 5090 achieves roughly 15–20fps at native resolution.
