If you set defferedshadows in skyrim_prefs.ini to 0. Shadows will work fine in 3d. The same can be achieved by setting fakevideocard to true in enbseries.ini. But if you use one of those both solutions you will loose effects of enbseries. But its better than no effects
. Effects thats still work fine is ssao (perfect in 3d), sunrays (no depth), DOF (sometimes for one eye only, because of different angle), other "normal" effects like lighting. All Day settings are not used, but interior settings. To adapt setting you have to change all day settings to interiorsettings entries.
Wonder why ssao is looking perfect in 3d and deferred shadows are only 2d?
I have found out that bloom of some user settings result in seeing ghostly shadows. But not the vanilla or enb one.
It would be sooooo cool if defered shadows won´t be 2d (no depth/at screen depth), because all other effects work fine while deferred shadows are on.
I have found a workaround for me: I deactivate the shadows completly but set them use defered ones and set facevideocard=false. So i can get all enb effects but loosing shadows completly, trying to compensate them shadows with ssao.
I of course still use the shaderinput folder to enhance the 3d look of sky and water.
