Meant to be Seen

hHllo, i m having some issues with vireio 2.02 and skyrim, it s a bit hard to explain but will try my best , i m having some light strobing in the shadows as for an example when loading a new game in the loading screen you should see the dragon and i m seeing below the dragon some strobing lights, having the same issues with trees and everything related with shadows , will try to download fraps and upload a video for you to understand better, can you help me pls.
i have tried vireio with portal 2 and works fine i m using a backup of skyrim with no mods and have uninstalled all mods, there is just nexus manager installed on my computer so i think i m using vanilla skyrim, nvidia 3d driver is installed too.
and this is my skyrimprefs.ini file (only put general, imagespaces and display sections of the files)

By the way this is my first message on this forum and i would like to thanks vireio's dev to allow us to play some non vr games freely.

There are two possibilities:

1. Is there a second skyrimprefs.ini file? You may have to set bDeferredShadows=0 in a second file.

2. Are you using an Intel 4000 series GPU? Are you running on a notebook computer with hybrid graphics of some kind? This may be problematic.

Do the shadows work in other parts of Skyrim? What about other games like Left4Dead?

well i have 2 skyrimprefs ini but i did put bDeferredShadows=0 in both, my computer is a notebook with nvidia gtx 675m and i7 3610qm 8gb ram but i use my nvidia gpu when playing skyrim (I used nvidia 3d parameter), should i change this line sD3DDevice="Intel(R) HD Graphics 4000 to sD3DDevice="nvidia geforce gtx 675m" ? left 4 dead is uninstalled but i have half life 2 and bioshock. the shadows are acting weird everywhere.

edit: so i finally solved my issue, i disabled ambient occlusion in my nvidia 3d parameter and now everything works fine, thanks for your time neil
