System Requirments/Performance

The project was optimized in several ways to ensure a high level of detail but with high performance and seamless compatibility with all Unreal Engine 5 systems such as Virtual Shadows, Lumen, and Temporal Super Resolution (TSR).

Key optimization techniques used:

  • Using Nanite for all static meshes whenever possible to improve rendering efficiency.

  • Disabling World Position Offset at a distance, particularly for foliage, to improve virtual shadow efficiency.

  • Grouping meshes into Instanced Meshes using the Final Prefab Blueprint.

  • Avoiding dynamic meshes by baking them into static meshes when blueprints are converted to Final Prefab Blueprints, minimizing runtime processing.

  • Applying material variations per static and instanced meshes randomly to enhance visual fidelity without using multiple materials, which would overload memory and increase rendering time.

  • Reducing texture memory usage by setting LOD Bias or Maximum Resolution per texture to fit runtime memory constraints.

  • Setting Max Distances Draw for small or thin objects to improve performance and keep only relevant details in view.

  • Applying Max Distances Draw for individual lamp spotlights on Traffic Poles Blueprints.

  • Adjusting level settings through the "B_Settings" blueprint for fine-tuned performance.

  • Optimizing materials and collisions
