I installed Farcry again now that I got a somewhat fast system and it plays very smooth so I start doing tweaks to enhance the game's gfx

too lazy to type, more info of what I did here

what I basically did:
- enable self-shadows
- enable HDR
- disabled 3D vegetations from turning to sprites.
- installed the 64bit content patch
and some other minor stuff.

Theres two things I want to find out how to do but I'm not sure it's possible to do via SYSTEM.CFG editing and short of hacking the engine code.

Maybe someone here know how to set it.
1 - you know how u see grass grows as you walk to toward somewhere. How to you increase the grass view distance?
2 - how do you set the distance (make it farther) before objects decrease their LOD?
3 - how do you increase the distance before the textures (of stuff like rocks and mountains) resolution decrease and looks crappy. I basically want the game to display the higher resolution (non decreased resolution) up to a farther view distance.

I have a C2D system with 4 gb ram and a 8800GTX and want to push the Cryengine1/farcry to it's max.
