Generally the settings look OK, except one thing: the way things are configured in your screenshot the game should open on the main display, not the Rift. Three things you should try:
1. Either select the second adapter in the “Graphics Adapter” listbox of the Skyrim options window (that may be what you meant by “adapter 1 trick” though).
2. Or Select “Show on Rift DK2” in the display adapter listbox of the vorpX config app.
3. Or Use the Rift as main display in Windows and leave vorpX at “Use System settings”. This isn’t exactly a comfortable solution, but the most compatible one. Shouldn’t be necessary for Skyrim normally though.
Apart from that there are two other things worth checking:
1. If you have the 0.6.0 Oculus runtime installed, go back to 0.5.1
2. If your notebook allows you to disable the integrated graphics card, do that. Just to make sure it’s not some Optimus graphics card switching issue.
