fMatsoDOFBokehCurve above 8 gives error

fMatsoDOFBokehCurve 9.0 and above gives this error:
C:\Program Files (x86)\Steam\steamapps\common\Assassin's Creed Revelations\Shader@0x0F3E1328(50,12): warning X3571: pow(f, e) will not work for negative f, use abs(f) or conditionally handle negative values if you expect them

The effect works but it gives an false error.

Where is that an error? It clearly states "warning", so nothing you have to worry about .

oh haha okey, but why is that warning showing up anyway?

Because it is a warning. A warning for the developer who wrote that shader, that there may be an issue she should look into.

Is this the same as the warnings/errors on version 19 where any of the dofs make reshade fail to compile? None of the Dofs seem to be working for me.
