Yes — while Nanite and Lumen deliver amazing visuals, they do impact performance:
- Nanite reduces draw calls dramatically, but it’s not yet fully supported on lower-end GPUs or mobile platforms.
- Lumen looks beautiful for real-time GI and reflections but can be heavy on the GPU, especially with lots of dynamic objects.
Tips:
- Test your scene on your target hardware early.
- Use Scalability Settings for optimization.
- Disable Lumen or Nanite on non-critical assets if needed.
