VR ULTRA on a Vive - is it possible?

[cmdr awesome]

After getting some poor results with my 980ti and HTC Vive in the Beta, I figured it was time to say "no" to dropped frames and bought myself a shiny new Titan X.

I plug it in, and full of confidence I fire up ED and select VR Ultra. I get maybe 30fps.
I then realise I still have SteamVR supersampling set to 2, so turn down the in-game supersampling to 0.65.
Much better, but still getting dropped frames

So then I turn off anti aliasing, and drop steamvr SS to 1.5
Now we're good - still get dropped frames on the station menus, but other than that spaceflight is mostly good.

I fly down to a planet surface and lose every other frame.
So I turn down the terrain quality settings from ULTRA to HIGH and it's mostly ok - again, I'm still seeing occasional frame drops.

Performance monitor shows that CPU, Disk and Network are all not bottlenecking - CPU is a fairly steady 60% and the rest are minimal.

Is there anyone out there who can get high quality results on the vive without dropping frames, and if so how do you do it?

I don't think any card out can get ED to a solid 90fps and no reprojection in a Vive. Not in stations, anyway. Titan X is only what? 25%-30% more powerful than a 1080? That's only good enough to get to maybe 70fps or so? Far short of the 90fps you'd need to hit.

To find out exactly what FPS you're getting in stations, turn off reprojection and turn on something like RivaTuner SS. It'll tell you what your actual FPS is. Whatever it is, it's less than 90fps because reprojection is kicking in. And if you're going to have to live with reprojection anyway, mine as well return that Titan X and get a 1080, then put the difference towards the eventual 1080Ti which will almost assuredly be able to hit 90+ in all situations in ED, for far less than you spent on that TX. Hell, maybe even Polaris will be able to do it.

I have reprojection turned ON at the moment (But 'enable Always-on reprojection' is OFF), and am watching the 'Framerate good' green/red bar in SteamVR settings to spot the problems. I'll have a go with RivaTuner - any tips?
I can't see a future 1080ti being more capable than the current Titan X - I'd expect it will sit in between the TX and the 1080.

Be sure to follow this guide https://forums.frontier.co.uk/showthread.php/274325-How-to-get-Elite-in-VR-looking-CRYSTAL-CLEAR-D the part where it ask you to "turn off Desktop Game Theater by navigating to Steam>Settings>In-Game" is important.

Must say you can't really go further, as you noticed the game is very limited by CPU latency on the Vive despite having a powerful graphic card. On beta 2.2 i'm wondering if the decrease in fps (latency) isn't pared to the recent change of FOV of the mirror screen. An option to disable this sccreen could help us to see if it have a moderate impact on CPU latency. If this latency is too high then you go above the 11ms limit and reprojection kick in despite having enough grphic power to run the game @ 90fps.

Tips for Riva Tuner? Just install Afterburner. RivaTuner comes with it. Add the ED executable to the list of applications RivaTuner looks for and enable the statistics you want to observe (gpu temp, power usage, fps, etc) in Afterburner's settings. Shouldn't take you too long and the information will be invaluable, never mind the opportunity to overclock it.
