4) Download low resolution textures mod "lowtex.7z": from:

6) Download mod disabling the SSAO effect:
http://junk.kegetys.net/nossao_mod.zip
7) Open "nossao_mod.zip" and unpack it to IL2COD folder - It will show as "nossao" subfolder like the "lowtex" on item 5)
8.) Download No mipmaps mod:
http://junk.kegetys.net/nomipmaps_mod.zip
9) Open "nomipmaps_mod.zip" and unpack it to IL2COD steam folder. It will show as "nomipmaps" subfolder under the IL2COD main folder.

-mod=nossao -mod lowtex -mod=nomipmaps If you like to enable all three mods. You can remove any of -mod=(something) if you don't want to enable it.
13) Start Steam
14) Start IL2COD with your newly created desktop shortcut.
There is also possibility to run mods directly from Steam by entering those starting parameters somewhere to steam (can't remember exactly how). Then you don't have to do items 10 - 14.
You can add also "-disablecomposition" launch parameter to shortcut with to disable Windows Aero UI to free some resources.
I hope this helps you....
