Discover the optimal system requirements for Lumion.
Unlike CPU-intensive rendering engines, Lumion operates as a real-time visualization platform, combining high-performance rasterization with ray tracing. Recent 2025 and 2026 versions have significantly increased reliance on hardware-accelerated Ray Tracing (RT). Performance now depends on a complex interplay of VRAM throughput, RT core generations, and system I/O, rather than just clock speed.
This analysis offers a data-driven overview of hardware specifications necessary for smooth Lumion viewport performance and reduced export times for 4K ray-traced sequences, utilizing current 2026-tier hardware.
Graphics Processing Unit (GPU): The Primary Engine
The GPU stands as the most crucial component in a Lumion workstation. Benchmarking for this report uses the PassMark G3DMark index and actual 4K render throughput to establish efficiency levels.
The Ray Tracing “Performance Delta”
The shift to next-generation architectures, such as NVIDIA Blackwell/RTX 50-series and AMD RDNA 4, has led to a non-linear improvement in rendering efficiency. Modern RT cores process “Denoising” and “Ray-Casting” calculations with considerably reduced latency compared to older generations.
GPU Performance Index (2026 Benchmarks)
Relative Speed is indexed against a baseline RTX 3060 (1.0x).
Insight: Although the RX 9070 XT provides a substantial 24GB VRAM buffer, excellent for large textures, the RTX 5080 and 5070 Ti frequently achieve superior throughput in Lumion. This is often attributed to NVIDIA’s specialized OptiX integration within the Lumion engine.
Processor (CPU): Managing the Geometry Pipeline
The CPU’s main function involves processing geometry from CAD software (like SketchUp, Revit, or Rhino) and transferring it to the GPU. Lumion relies significantly on single-threaded performance for scene management and the LiveSync bridge.
- Professional Recommendation: Intel Core Ultra 9 285k or AMD Ryzen 9 9950X.
- Metric of Success: A Single-Thread CPUMark score of 3,600+ is recommended to ensure the GPU is never “starved” of data during real-time navigation.
Memory (RAM) and VRAM: Avoiding the Memory Swap
Lumion necessitates that the complete scene, encompassing textures, geometry, and the asset library, resides within the GPU’s VRAM. If VRAM capacity is surpassed, Lumion transfers data to system RAM, resulting in a considerable performance slowdown.
- Minimum VRAM: 12GB (Found in the RTX 5070).
- Recommended VRAM: 16GB–24GB (Commercial and urban scale).
- System RAM: 64GB DDR5 is now the professional standard to allow for multi-tasking between Lumion and high-poly modeling applications.

The following chart compares the time (in seconds) required to export a 4K photorealistic still with Ray Tracing (v2.0) enabled.
Fig 2. VRAM Demand Scaling by Complexity
As model complexity grows with higher polygon counts and texture resolutions, VRAM consumption increases exponentially. The use of “Fine-Detail Nature” assets is a significant factor in VRAM exhaustion.
Recommended Configurations (2025–2026)

Conclusion: The VRAM “Hard Limit” for Lumion
Regarding Lumion system requirements, the shift to 2026-tier hardware emphasizes a crucial trend: the VRAM threshold. While the RTX 5070 is sufficient for most residential projects, the 16GB buffer of the RTX 5080 or 5070 Ti represents the ideal balance for professional architectural visualization. For extensive city-scale environments, the 32GB VRAM in the RTX 5090 is essential to prevent severe performance degradation caused by system memory swapping.
