Your camera 3D model is slow mainly due to high polygon count, unoptimized textures, underpowered hardware (GPU/CPU/RAM), or resource-heavy real-time effects—these increase computational load, causing lag or stuttering.
- **High polygons**: Too many detailed faces (e.g., unnecessary lens curves) overwork your GPU. - **Large textures**: Uncompressed or overly high-res images (like 8K) drain memory. - **Weak hardware**: Outdated components can’t handle complex 3D data. - **Heavy effects**: Real-time reflections, soft shadows, or depth of field add extra processing.
To speed it up, reduce polygon density (use decimation tools), compress textures (convert to .png/.dds), upgrade hardware if needed, or disable non-essential effects in your 3D software.
