no shadows in latest update

all shadows including undercar disappear in latest update.
if I revert to v.1111 all is ok.
when I use opt out of betas to get latest version shadows are gone again.
tried: clearing shaders, cbash, regenerating player.json, toggeling through all shadow options.

 

Delete DX11 in Userdata folder ?

 

you the man Ari, thanks that worked! have a good weekend.
