Standard DX9 doesn't support high res textures, light and shadows.
DX10 Crysis enabled Very High, using those files people were able to mod Crysis DX9 to look the same.
There's a reason why very high and extreme does almost nothing in C2, DX9 can't push the game any futher than high i.e. C1. People can stay negative all they want, a DX11 patch is coming and it will make your PC BSOD, lol.
It's about hardware requirements that shader model 3.0 required. SM 3.0 (which came with DirectX 9.0c) required GPUs to support up to 4096*4096 textures.
The reason Crysis may not have texture resolutions to your liking has nothing to do with DX9 vs DX11.
Shadow mapping requires rendering part of the scene twice (or more than twice) from different angles depending on the source of the light. This creates a 'shadow map', which is just a texture. The size of this texture affects performance, the larger it is, the larger the impact of the shadow cast.
Chances are that the shadow texture resolution was kept smaller for performance reasons. However, it makes no sense why they wouldn't include a graphics option/slider to adjust shadow detail. That option would take all of a couple of days at most for a programmer to implement fully I would think.
