Hi -
The System Requirements for both WWT 5.0 and WWT Legacy require:
- Discrete graphics card with 512 MB VRAM, DirectX 10 or DirectX 11 compatibility, high-end GTX 480 class or better, and 1 GB VRAM recommended.
The Intel Graphics cards are generally not powerful enough to provide a smooth running WWT experience. Replacing the Graphics Card will provide a huge improvement to your WWT experience.
