I am using shadow map in a project of mine (with pixel shader), and all was working fine until catalist 3.8. (D3D)
all work fine with the ref renderer. I waited few months hopping ati would correct the bug. but i finnaly gave up to wait for a fix and modify the shader I used to resimulate alphatest (using a texkill). Unfortunatly this make the shader 2 instruction bigger (a sub and a texkill), and my engine has currently a pixel shader Bottleneck.
my question is am I the only one who got problem using alphatest on a texture rendertarget? i tried a lot of thing but it really seems its broken. (even using never , always as alpha func has no effect on rendering th epixel is allways rendered)
thanks
