Reviews praise D5 Render for fast, real‑time results, intuitive workflow, and strong integrations with SketchUp/Revit. Users highlight cinematic lighting, solid path tracing, and AI features (upscaling, denoising) that speed client-ready visuals. Many switched from Lumion/Enscape for better balance of speed and quality. The built-in asset/material libraries save time, though some note many items are Pro-only and large scenes demand strong GPUs. A few mention a steeper learning curve or limited advanced controls versus V-Ray/Corona. Overall, an efficient pick for professional ArchViz and student presentations.
