I see all these pictures of higher detailed ground textures like this one:

I installed the EECHAllmods.exe and checked all the selections, including textures. But when I start the game all I see are the original ground textures. The winter areas I've tried are all completely white.
How do I get the nice ground textures?
Other than that I must say I'm very impressed with the game now when I hear the LB2 voices and new (new to me) weapon and impact sounds.
