Hercules Stingray 64
The Hercules Stingray 64 is based on the ARK Logic 2000MT chipsoft. It is a basic 2D-graphics card from 1996. In it's day the competition was slowly moving to 3D-functions although most of them we're basic, slow and often required a specific API (OpenGL, Direct3D wasn't mainstream).
The ARK2000 is the successor of the ARK1000-series. The ARK1000 is a very good performer for DOS-games. I guess this Hercules Stingray 64 would be even faster.
