IS your shadow casting model visible? As otherwize the shadows are probably clipped away together with it.
Other than that it basicly just works. At least for me...

lowering your alpha on the shadow should improve frame rate also

@Slin
yes all my models is visible and passable. Shadow is well seen on all models, but also shadow passing through my models - i do not know if this is normal and how stop this? For collision i use wed blocks under models with none flag. Perhaps the problem is that?

@Badapple
how to do it?

i know with lite c its like this , but im not up to date with a8

mat_shadow.alpha =40;//place this line at the begining of function main

replace 40 with any value 0 - 100

let me understand, all your models are casting shadows?, if so....that would lower your frame rate, or you are not using stencil shadows at all, but a shadow mapping post proccessing shader....again is slower than just your player having it's shadow on.

Badapple, that shouldn't have any effect on the speed.

CodeMaster, that is a general problem with the way stencil shadows work and nothing specifically related to gamestudio. The only solution is to have all objects casting shadows, as that will of course hide the "wrong" shadow in the shadow.

@slin it most certainly does affect your fps , the lower the value the better the boost.

really doubt that

me too -.- see no technical reason why it should...

It is nothing but the alpha value of a black fullscreen quad...
