Real-time Ray Tracing for Architectural Visualization
summary
Shows how Unreal Engine 4.25 runs the freely available ArchViz Interior sample on an RTX 2080 Ti, how to enable DX12/movable lights and ray tracing, and where to flip console CVars. Gives concrete costs: scene drops from ~60 fps with GPU 17 ms to 14–15 ms when ray-traced materials are disabled, reflections need max bounces 1→3 to remove black gaps, samples up to 32 cut performance to ~30 fps. Compares final gather vs brute force GI, notes path tracer is offline and High-Quality Media Export can stitch tiled 20K renders.
