Hi...
I have a problem when I add shadow to my game
I tried the ShadowVolume but when I turn it to active
the speed of the game comes to be tooooooooo slow

some notes:
- I tried ZShadows but the same problem

-The map of my game is 3DS and its like a city so its has
a lot of buildings (The city in one 3DS file)

-My PC : 3000/2m , nvidia 9400 , DDR3 2G the memory
