Vive software sort of works. I downloaded a free game VR funhouse that I demo'd in a microsoft store. I was able to sort of play it, but I need a new videocard as it's shaky and slow. (I have a K2200 Nvidia Quadro workstation). I ordered a P4000 today. I haven't bought any steam software with money yet, but no errors there.
My only problem is that the microsoft keeps popping up with that same window over and over. Clicking to search for the app results in nothing, yet the pop up comes right back. I have to control-alt-delete to end the program to not constantly see the pop up warning.
