RenderStateManager.SlopeScaleDepthBias Property
[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]
Retrieves or sets a value used to determine how much bias can be applied to coplanar primitives to reduce flimmering z-fighting.

Property Value
Type: System.Single
Value that specifies the slope scale bias to apply. The default is zero.
Remarks
Polygons that are coplanar in your 3-D space can be made to appear as if they are not coplanar by adding a z-bias to each one. An application can help ensure that coplanar polygons are rendered properly by adding a bias to the z-values that the system uses when rendering sets of coplanar polygons.
The following formula shows how to calculate the bias to be applied to coplanar primitives.
bias = (m * SlopeScaleDepthBias) + DepthBias
where m is the maximum depth slope of the triangle being rendered, defined as:
m = max(abs(delta z / delta x), abs(delta z / delta y))
