Settings Menu: Shadow Quality -- What to change?

[Zitheral]

I'm working on a settings configuration menu and I'm not familiar enough with UDK to determine which options should be changed and what they should be set to for a general Shadow Quality of "high" "medium" and "low" option.

These are the options available:

DynamicShadows
    (UBOOL) Whether to allow dynamic shadows. 
LightEnvironmentShadows
    (UBOOL) Whether to allow dynamic light environments to cast shadows. 
MinShadowResolution
    (INT) min dimensions (in texels) allowed for rendering shadow subject depths 
MaxShadowResolution
    (INT) max square dimensions (in texels) allowed for rendering shadow subject depths 
ShadowTexelsPerPixel
    (FLOAT) The ratio of subject pixels to shadow texels. 
bEnableBranchingPCFShadows
    (UBOOL) Toggle Branching PCF implementation for projected shadows 
bAllowBetterModulatedShadows
    (UBOOL) Toggle extra geometry pass needed for culling shadows on emissive and backfaces 
bEnableForegroundShadowsOnWorld
    (UBOOL) hack to allow for foreground DPG objects to cast shadows on the world DPG 
bEnableForegroundSelfShadowing
    (UBOOL) Whether to allow foreground DPG self-shadowing 
ShadowFilterRadius
    (FLOAT) Radius, in shadowmap texels, of the filter disk 
ShadowDepthBias
    (FLOAT) Depth bias that is applied in the depth pass for all types of projected shadows except VSM 
ShadowFadeResolution
    (INT) Resolution in texel below which shadows are faded out. 
ShadowFadeExponent
    (FLOAT) Controls the rate at which shadows are faded out. 
ShadowVolumeLightRadiusThreshold
    (FLOAT) Lights with radius below threshold will not cast shadow volumes. 
ShadowVolumePrimitiveScreenSpacePercentageThreshold
    (FLOAT) Primitives with screen space percantage below threshold will not cast shadow volumes.

Has anyone taken the time to implement a sort of general "Shadow Quality" configuration for their game? I know each game is going to be somewhat different, but it would be nice to have some place to start.

Noone has done anything with these variables or ShadowQualityFilterBias?

That's what I'm working on now. I have two options, Character Shadow Quality and Environment Shadow Quality. I use the variable MaxShadowResolution for characters, and MaxWholeSceneDominantShadowResolution for the environment.

I change the MaxShadowResolution var.
when shadows are set to "Very Low", I disable dynamic shadows and use [this] (on characters only)
then I got a "Disabled" value where dynamic shadows are just disabled

in my experience the shadow quality filter does nothing at all
