OpenGL: Unigine Heaven
Synthetic though it might be, Unigine Heaven 4.0 is a popular benchmark for testing gaming-oriented graphics cards under DirectX 11. Instead, we're swapping over to the metric's OpenCL render path. Here's a quick overview of its main features, according to Unigine.
- Comprehensive use of hardware tessellation, with adjustable settings
- Dynamic sky with volumetric clouds and tweakable day-night cycle
- Real-time global illumination and screen-space ambient occlusion
- Cinematic and interactive fly/walk-through camera modes
Nvidia's GeForce GTX Titan shows its gaming focus and draws way ahead of the GTX 680. The Radeon HD 7970 GHz Edition is the only card that gets close to it (which isn't bad for a graphics card available for half as much money).
