I wonder why they end up under DX8 cards. Something off in the databases, unknown cards still getting a generic DX8 label before encoding after all these years, or what else could be the reason?
"DX8 and below", probably the field is empty or has an error code.
- if %DirectX = 12 -> group DX12
- if %DirectX = 11 -> group DX11
- if %DirectX = 10 -> group DX10
- if %DirectX = 9 -> group DX9
- else -> group DX8 and below
