Now that we are getting very close to integrating EDGE into DCS, I can share a few more details.
1- DirectX 11 / DirectX 11 Windows 8 based.
2- Can support up to four GPU (either SLI or CF).
3- Uses clip maps.
4- Two cloud layers can be created with options for none, cumulous, cumulous nimbus, and stratus.
5- Terrain shadow projection is supported.
6- World can be as large as the designer wishes them to be, it is more of a question of development time / map detail.
7- Option to project map on globe surface.
