HYDRA: Electric Bloom
We are preparing Electric Bloom — a new real-time demo for HYDRA.
It is a beautiful but heavy 4K scene running on Unreal Engine 5.8, built to help HYDRA test GPU/VRAM overclock stability.
Today, there are very few modern tech demos for testing GPUs. For most people, 3DMark is still the main reference point. But modern GPUs no longer belong to the era of old benchmark scenes. New architectures should be tested with modern workloads: RT, Lumen, heavy shaders, VRAM pressure, Nanite geometry, temporal reconstruction, and real 4K scenes.
That is why we are building Electric Bloom for HYDRA.
Inside the demo: Lumen GI/reflections, Hardware Ray Tracing, Nanite, Virtual Shadow Maps, TSR, Virtual Textures, Niagara, and a dense foliage-heavy environment.
We also added our own optimization layer: RT profiles L0/L1/L2, PSO warm-up, Shader Pipeline Cache, VRAM control, and performance telemetry.
Electric Bloom also includes a built-in artifact scanner. It analyzes the final frame and catches the kind of issues that often reveal unstable overclocks: flicker, sparkle, white flashes, luma/chroma artifacts, overbright or non-finite pixels, plus GPU crash/TDR/device removed/out-of-VRAM signals.
Electric Bloom is not just a pretty flythrough. It is a modern RT/Lumen workload for checking if a system is actually stable.
The visual base of Electric Bloom is built on Epic Games’ Unreal Engine Electric Dreams Environment sample, but the demo has been heavily adapted for HYDRA: RT/Lumen workload, 4K L0/L1/L2 profiles, PSO warm-up, VRAM control, telemetry, and a built-in artifact scanner for overclock stability testing.
