FEAR 1 is setting WINED3DRS_DEPTHBIAS = -0.5, which is a pretty large value.
E.g. Fear itself uses -0.000000178... for the decals, which is a sane value.
The d3d value is simply added to the z coordinates of the fragments, so -0.5 is
half the depth range.

I've no idea yet for a proper fix. My first guess would be that there's
something that disables the polygon offset. The game is never using
pretransformed vertices, which excludes the most likely candidate. Other things
I can imagine are that d3d adds the depth bias after clipping, that there is a
maximum bias or that the depth bias is ignored if the pixel shader writes Z
values.
