Hmmm, curious play Kinger 
I certainly hope that you find the lateral move worthwhile. At least we will have some subjective data from a member comparing the two. To get start, you want to have Windows updated to the latest version, run the hardware wizard in WMR, have Steam installed, and Windows Mixed Reality for Steam (beta) in your Steam Library. My launch method is to put on my headset, which will start up Windows Mixed Reality (or start WMR via the icon), take headset off and launch Steam VR, then the sim. Sounds cumbersome, but really gets pretty automatic after a while.
I have posted my settings in the other Reverb thread. YMMV. For pretty much all sims/games, IMO your resolution should be as close to 100% as possible. Otherwise your system and headset work really hard pushing the extra pixels. DCS specific, chose the VR preset, then set MSAA to 2x and PD to 1.0.
Let us know how it goes.
