DX 11 , Threaded Drivers ?

Unfortunately, because no other games have used this feature yet, neither Nvidia nor AMD have publically released threaded drivers, so users may not experience all the benefits just yet. We decided to keep threading enabled for Civilization V, however, because we are continuing to work closely with Nvidia and AMD on their support for multi-threading. We expect publically available threaded drivers shortly.

One big difference in the DX11 version is the terrain. On DX11, we are able to have a much more detailed terrain, since we are able to get a 4x compression on the textures.

Bit of an odd one - some slight issues aside DXT1c will give you 4x compression also even on DX7, 5-6x depending on how you handle mipmaps.

Does seem odd. Can't imagine they invented a new compression technique, it's been covered for years...

The DX11 version does have much better textures though... Not amazing, but pretty good

Edit:
Civilization V uses the Direct Compute Features for a new proprietary variable bit-rate texture compression. Users will notice that on high end DX11 native hardware, the leaders will appear almost instantly, regardless of how many civilizations are present. There will also be no paging-in on the textures in the background as they are loaded since the 2gigabytes of leader textures compress to less then 150mbs altogether. This type of compression was, until recently, considered impossible or impractical, but we believe this is just the tip of the iceberg for what can be done with Direct Compute.

There you go!

Does this make any sense...?
