Note : It'd seem that increasing only fShadowDistance to 6000 from the medium preset give acceptable results, without the tremendous performance hit. The other workaround is to use Shadow Boost.

Object Detail Fade[edit | edit source]
Note : While lower values exists in presets, all 4 settings Low, Medium, High and Ultra will save the same value in the INI file. Thus, the values below are related to the presets, and not the actual setting, which always set the two parameters to 999999.
