Did do a search on this one thing related popped up with no replies.

Seems that when I trade with an Merchant and I have EDE or another companion with me it crashes the game with a video error. But yet if I have no Companion with me game runs flawlessly for hours. Has a new bug crept up in recent DLCs/Updates?

So I did a clean install of Nvidia's latest drivers, works a bit better but still does it. I drop the companion everything smooth.
