I'll await Aviar's reply.
The way I have read into it, you need to put two lines for the forest setting...

Like this

Sky=2
Forest=4
LandShading=3
LandDetails=2

LandGeom=3
TexLarge=1
TexLandQual=3
TexLandLarge=1

VideoSetupId=17
Water=3
Effects=1
ForceShaders1x=0
PolygonOffsetFactor=-0.15
PolygonOffsetUnits=-3.0
Forest=4

Extremely useful thread and thanks to every one for adding their comments to squeeze the best out of the game graphics.

And a big thanks to Oleg for his input and creating a fantastic SIM in IL2.....(but not for smoking my ass with a FW :evil: ......I assume he is the on-line player with the HL call sign 'OLeg Maddox'......:grin:)

Alpha has it dead right. Just tried this out, and forest=3 gives 3D trees in towns as most of us should be aware, but forest=4 seems to roughly double the quantity. Also the number of 3D trees in open country seems to go up.
This was a quick tryout though so can anyone verify?
Cheers.

Cheers Alpha ;)

Just to make really clear!

Bit of a wild goose-chase for me. When I use the settings below, the first Forest=4 setting reverts back to Forest=3 as soon as I exit the game, with no difference at all in the trees while the config still says Forest=4 during game-play.

Same here, just checked. First one back to =3 and Bottom one stays at =4
Never mind! I can't see the woods for the trees anyway according to my missus! :grin:

+1, even with two lines of forest

Try right-clicking on the conf.ini file, select properties, then check the 'read only' box, then select 'ok' or 'apply'. I found this seems to make the settings stick.
