Update to the Heaven v2 demo, that has been an long-standing benchmark for many people. Though it's largely the same as the v2 demo, it does add a couple of new set pieces - particularly a new airship. This title is more demanding than the previous iteration, and adds a new tessellation options.

The Heaven demo continues to offer options for testing in DX9, DX10 and DX11 code paths. We have narrowed our testing to DX11, and are no longer testing the DX9 and DX10 code paths. The DX9 and DX10 were more CPU dependent and less of a test of the strength or weakness of the GPU. The DX11 truly stresses a GPU.

The Radeon HD 7770 GHz Edition pushes past 30fps at 1600x900, and it almost hits the performance level of the Radeon HD 6850. A drop in AA and it would hit 30fps at 1080p. It averages about a 5% performance increase over both the Radeon HD 6790 and the HD 6770. Like all cards in this range, the Radeon HD 7770 turns in a slideshow performance in Eyefinity for the Heaven demo.
