My shadow engine was working fine in D3D8, but when I ported it to D3D9, the Z biasing stopped working (im using a GeForce4 Ti 4400 ). They changed Z biasing to depth biasing, and now the debug info says "Unsupported renderstate D3DRS_DEPTHBIAS". I know its supported though, because it worked with d3d8. Any ideas?
