Ok I have a few questions for who knows or has tested the Ce3 :

The 3d directional waves that were present andremoved in Ce2 are back and working in ce3?

Is the engine large alloweing Open world streaming sand till what sizes?

is the engine supporting the tessellation with direct x 11?

3. yes

2. no.

3. No. There is no dx11 support in the free sdk yet.
2.Read through this thread. It should answer that question. viewtopic.php?f=314&t=74175

This wasn't exactly the question though; Cryengine 3 (Crysis 2 patch 1.9 build) does support DX11 and tessellation.

Large maps. Yes.
Streaming Worlds. No. (there is no dynamic heightmap streaming)

how bout n1?

Also how many textures are possible ot load this time? IS streaming content available? so to allow more texture loaded according to the area? Hpw bout the directional waves? How big are the maps that can be done above 16 x 16 kms of the previouse editor?

If you mean terrain layer materials, the limit is still 15. I'm not sure if different terrain tiles allow different materials (usually in 3D engines the amount of materials is limited to terrain chunks), in any case I don't know how to do it.
Haven't looked whether they're still present, I wouldn't hold my breath about it.

According to cwright, 64km x 64km - about 4096 km² in total area.

15 layers is already pretty huge number comparing to other engines. It eats a lot memory. In other engines it is recommended to use 4 layers but it is true that you can use more than 1 terrain in scene. However it would be awesome to have terrain system like ID Tech 5 with gazilions layers:D

I am pretty shure that the gamebryro engineand the new creation engine bethesda used foscauch 15 textures for ground, what systedo they use?
