Autogen tweak that might help
Many of you have been frustrated that you can't control the density of autogen trees verses buildings because we only have one slider to cover both of them. Some have also been frustrated that our lowest autogen setting is more dense than FS2004 at max density.

If you add these two lines to the [TERRAIN] section of your FSX.CFG, you can define the max number of objects in a terrain cell for trees and buildings independently. The slider will scale down from the numbers you set as the slider is moved to the left. The max tree value in FSX as released is coded to default to 4500 and the building default is 3000 (as shown below) and the absolute max FSX will recognize at all is 6000. Of course if you raise the values beyond the defaults, you will obviously be increasing density and lowering fps (so don't complain if you do this...). The point in sharing this information is that with these settings you can specify what the values are yourself. Set buildings or trees at 0 and you won't get any of those objects no matter where the slider is set.

TERRAIN_MAX_AUTOGEN_TREES_PER_CELL=4500

TERRAIN_MAX_AUTOGEN_BUILDINGS_PER_CELL=3000


I set mine at 1500, and 1000, respectively, and in the FSX.cfg files I set SHADERS-CACHE=0 and this now gets me double digit fps.

I'm surprised to see how flexible and more useful the FSX.cfg file has become. 8)

We were already surprised by the possibilities of FS9.cfg, I was expecting some more surprises from FSX.cfg as well  8)

Very nice tweak by the way, thanks to the developper Smiley

Were you talking about:

SHADER_CACHE_PRIMED=0

by any chance, Felix?

Another tweak that works for me (in addition to the above) .....  Increases my fps, in "medium low" but I get acceptable (to me) fps when I increase the settings to "medium high".

TEXTURE_BANDWIDTH_MULT=400
