My Mobo has 4 full pci E slots that are Gen 3 and then 2 small slots that only the wigig can fit in that I believe are gen 2.
With the full PCI E slots when the wigig is plugged in the vive wireless cant recognize the card even though the lights blue on the card. I tried all the slots.
My bios has them set to auto by default. I tried setting them to 4x and the PC wont boot. Tried setting to force gen 3 PC wont boot. Under auto it boots fine.
Threw the card back in the small slot, left on auto and launched games direct from steam avoiding the steam overlay and it worked fine for the 30 minutes I played last night. Fine tracking, Fine graphics, just a pain in the ass to have to take the headset off to swap games.
I'll try and get a longer game run in today. Seems there are quite a few different issues going on here with this thing and its not one simple fix.
