I dont think direct works in anything yet does it? Still waiting on a good wwii flight sim! Dont want to spend loads of money on WT because im not sure theyre going to fix their issues and quite frankly youll get spanked by everyone right now, have big hopes for BOS!
While a bit of a pain to get working (and you NEED an Nvidia card) DCS is free to try and you get WW2 planes.
Give it a shot.
Also things are changing daily with the Rift as more developers spend more time with their projects. There's actually quite a few that work in Direct mode now but it's really inconsequential as you can easily mirror what's being displayed in extended mode with OBS (

Quick question, whats the consensus on CV1 being powered by a single 970?
Technically it's going to work, but realistically I wouldn't buy a PC NOW with the intention of it working the best with the CV1.
1) We don't have a time frame for the CV1
2) Oculus are in direct comms with Nvidia and AMD so new cards could be getting made specifically with VR improvements in mind
and, as always, you have that "PC problem" where no matter what you get there will always be SOMETHING you can't run.
Key thing to remember is that even with the DK2 the 1080p resolution isn't identical to just running a game at 1080p on your monitor. For starters it's 3D, so everything is rendered twice and two, keeping a minimum refresh rate of 75fps is ESSENTIAL.
Not a "oh no, I noticed a tear because I had vsync turned off and it dipped below 60fps for half a second". If your frame rate drops below 75fps, at 2x1080p for half a second every minute of gameplay, I'm willing to be that after 10 minutes you couldn't carry on. It's so noticeable, and so jarring in VR that it really makes you feel sick, super quick.
Then of course remember that the spec that is more likely for CV1 is going to be a 1440p screen at 90Hz minimum.
So yeah my two cents is that, yes a GTX970 will work, and likely work well for a couple of games - but it's not going to be particularity future proof.
