Just kept crashing whit out even giving a decent crash in event log.
Funny solution reboot into linux install run from windows drive and voila works. (install just to create the /my documents/mygames/falloutfolder/)
Usually one has to go into windows to play games Well i guess it proves once again linux is more useful then one might think.
Probably not helpful to most of you ppl having issues but us dualbooters might find it helpful
