Don't downgrade, just wait for the updates to come. My computer is about as half as powerful as an ideal computer for emulating Gc/Wii in vr, and that really just kills the entire experience, so there's no point in playing games all the way for me. I don't get vr sickness but I get headaches, and the low framerates kill any enjoyment to be had.
To add to that you also need the fps hacks, the rift runs at 75 and gc/wii runs at 20/30/60 fps. You need the full 75. And to add to all of that the dk2 resolution is like staring a foot away into a wall of 480p tv from 2000, the kind you could rub the static off of.
Fix all those issues, all the best oculus games out right now are in dolphin. Smash bros is like turning your desk into a fighting stage where you can stick your head in and look at the fighters, Metroid prime plays like it was designed for the rift. Super Mario Galaxy is the coolest of them all, bring down the scale and you're following mario jumping from soccer ball to soccer ball planet in the middle of space. There's definitely merit to revisiting games in vr, especially once all the kinks are worked out.
