I edited that in as an alternative.
In documents/mygames/skyrim/skyrimprefs you tried this?
iBlurDeferredShadowMask=1
fInteriorShadowDistance=1000.0000
fShadowDistance=5000.0000
iShadowMapResolutionSecondary=4096
iShadowMapResolutionPrimary=4096
iShadowSplitCount=2
Or just these 3 edits?
fShadowDistance=400.0000
iShadowMapResolutionSecondary=8192
iShadowMapResolutionPrimary=8192
