Just had my first DPC_WATCHDOG BSoD after maybe 8 hours of total wireless play time. It could be complete coincidence but I had just adjusted some performance settings in SteamVR. Namely, put the resolution on manual and turned it up to 120% (recommended 58% which seems low for a GTX 1080 and 2700X CPU) and turned off interleaved reprojection. Fired up SteamVR, clicked on my library to try a game and boom!
Unfortunately, battery is too drained to try to recreate with/without the performance tweaks to see if it's coincidence or casaul.
Prior to this I have had numerous freezes of the HMD, SteamVR or the Wireless card (haven't figured out which) resulting in the scene being replaced by a grey (or cyan since I can't see cyan) blank scene requiring multiple steamvr or headset restarts. Perhaps those have all been lesser version of the same failure?

Also potentially significant in case there's a commonality here: I'm on the October Update of Windows 10 (1809)
