The problem is that it will require 75-90 hertz and a resolution of 4K.
Not necessarily. The framerate, yes, but it won't necessarily need full 4K. The main complaint I see of the 1080p screen isn't so much the rendered resolution as the physical resolution and the "screen door effect". A 4K screen would negate much of that, while the game could still be rendered at 1080p. With decent AA, you wouldn't really get much in the way of jaggies or visible pixels, even if it's not rendering native. And if your computer can do it, you can bump it up to something in between like 1440p.

At that point, complaints about softness or lack of detail would have nothing to do with the Rift, it would boil down to "buy a better computer". The Rift itself would be future-proofed for a few years at least.

I've been having trouble getting mirroring to work so other people can see what the riftee is seeing. It's much more enjoyable to demo this way with a group of people that just listening to their "oohs" and "ahhs", but a lot of the demos out there don't seem to do this in extended mode.



I came across a reddit thread talking about using Open Broadcaster Software to get a pseudo-mirroring effect. Not sure if it's been talked about in detail, but here's how I got it working.

I'm running my rift in Extended Mode, with it as the secondary monitor on the right side.

1. Download and install the free streaming tool OBS from https://obsproject.com/.
2. Launch OBS.
3. Turn on the rift and launch the demo you want to use using the DirectToRift exe.
4. Alt-Tab back to the OBS window.
5. Right-click in the small "Sources" window near the bottom of the OBS window, and select "Add".
6. Enter anything you want as the name.
7. There are a lot of different options here, but from what I've tried, Game Capture seems to works best, so select that.
8. In the window that popups up, there should be an application dropdown at the top. Choose the demo from that dropdown and hit OK.
9. Hit the Preview Stream button in the bottom right.
10. Alt-Tab back to the demo window.

The steps above work about 90% of the time for me. Most unity demos work with this, but LFS and a couple others don't for me.

You sir, are amazing! This works like a charm.

This post has to be in the OP :D

how is war thunder with the DK2 ?
It is OK. Not more. The scaling is off, especially for the pilots body. If you don't move your head or still looks good but something is wrong with the distortion. Your view bends in a weird way. That makes you sick pretty quick. And I wasn't able to hit anything die to resolution and aming problems.

Try it, look around and wait for more patches.

It's highly unlikely that the consumer model will have a 4K display. 1440p is expected.
Well the Samsung mobile 4k screens are out early next year and seeings Oculus likes using Samsung screen theres a good chance that the CV1 will use the Samsung 4k screen......obviously you wouldnt need to run the thing at 4k res if your system wasnt up to it but it would be future proof!

Just tried HL2 VR... uh well. I dropped out after 10mins.
- Abysmal black smearing and light color smearing for me (probably I didn't have low persistance if it's actually possible to have it in HL2 as of now)
- The camera control is too weird for me...
- Loading times are sorta long. With no headtracking, this is very unpleasant.

Do you have a source for those Samsung mobile 4K screens being released early 2015? As far as I'm aware they haven't even launched a 1440p phone yet.

4K introduces issues other than increased processing power requirements as well. HDMI/DVI-D isn't going to be sufficient for 4K video at 90 Hz. I'm not sure even HDMI 2.0 or DisplayPort can handle that either. So far most of the 4K speculation for CV1 seems more like wishful thinking to me than anything.

We could use a custom resolution @ 3840x1080 or 1920x2160. Should perform quite good and would also look fantastic on a 4K rift.
...and there wouldn't be a way to possibly send that resolution to the device, unless Oculus is also going to get into the video card industry and the display adapter industry. Both HDMI and DisplayPort have specific resolutions and framerates in their standards, and neither HDMI 2.0 nor DisplayPort 1.3 are due out any time soon.

For every demo except one, I have found that selecting record (using Game Capture) before even starting the demo/game will result in it recording and showing up. I had to use Direct to HMD and do a monitor capture for only one demo.

You could simply upscale from 1080/1440 if they use a 4K panel at all. I'm quite sure Project Morpheus will use this trick.
All that does is reduce the screen door effect. The reason people want 4k is because 1080p/1440p becomes a limit to the distance one can see and parse text. Upscaling is useless for VR.

What looks better - a native 1080p image, or a 1080p image upscaled to 2560x1440?
Generally a native 1080p image should look better as it will have 1:1 pixel mapping. The benefit of 1440p for upscaling is that it will reduce the screen door effect in VR. It's hard to say which would look better for VR in practice without seeing them.

Hopefully the devs do get the judder problem fixed. Only the desk demo seems to run smooth for me. Tuscany and every 3rd party game is just a mess. Of course my multi-monitor setup isn't helping. Neither is having one monitor 120hz and another 60hz.
The only thing that has fixed stutter in a few things for me with some of the demos is to disable literally every single monitor on the system except the Oculus, and start the game on the Rift itself. This is a challenge since you can barely see your desktop but with some careful maneuvering it's possible.

Half Life 2, for example, cranks out 200+ FPS at all times but stutters like mad unless I do this.

1:1 pixel mapping is a bit more complicated with a HMD than a regular screen. You'll never have 1:1 across the entire display. And to have 1:1 in the center area while filling the whole FoV you need to render at significantly higher than native display resolution.
 
I checked out That Booty earlier today (Demo Download). Like Ninja Discount Warehouse, you control the game solely with the headset. It's a skiing game where you try and reach the finish line in the shortest time possible while dodging various obstacles. Lean forward to go fast, lean back to go slower, and lean left/right to dodge. It's simple and is only worth a few minutes of play, but there was enough there for me to try and get my time lower. I was too busy looking at dat ass to really do too well, however.

My only real problem with the demo is that I couldn't figure out how to restart it without completely exiting. The ski run is pretty short, so having to exit out and restart the demo was a little annoying. Let me know if you play it and I just missed something.

Edit: Talked to the developer. Hitting the space key should restart the demo. I must have only tried it when I was having recording issues with the Rift.


I also played Resistance - a stealth VR demo the other day (Demo Download). You have to locate and hack servers while avoiding detection from guards and cameras. A green line on the ground points you in the general direction you need to go, but that's the only assistance you'll get. I found the demo to be too difficult to be very enjoyable or make any real progress. When you fail you won't always be clear on how, and there's a lot of trial-and-error as you test the limitations on what you can get away with, figure out how far guards can see, etc. I liked peeking around corners and the concept of a first-person stealth game in VR, but it needs a lot of work and more information on what you're doing wrong to be much fun. I played the demo before recording, but after a while I wanted to see what I could get away with and how much running I could do before getting chased down. The developer says it can be completed in less than 15 minutes, so maybe someone else will be better at it than I am and actually finish it.

Another issue with the demo is that after a little while it would start to judder and there would be a delay in my movement and when I saw it on screen. Only exiting the demo completely and going back in fixed it.

Finally got Titans of Space to work by forcing d3d9. So damn good. The low persistence and colors are such an upgrade to the experience. Watching moons in orbit is mesmerizing. Love the polish. I want a LOT more of this kind of stuff from Drash.

It doesn't matter. Oculus VR has a special deal with Samsung. They won't get a smartphone-display, they will get their own custom display. So it's absolutely possible that we will see a 4K CV1.
There seems to be a small group of people who think it's possible (if not probable) that CV1 will have a 4K display. Despite the tech being really early, and other limiting factors, I see this as highly improbable. Even though Oculus was purchased by Facebook, they are still going to want to make the thing cost effective enough to meet a consumer price point. Selling at cost or near cost doesn't mean they can put in any screen if the price doesn't match expectations. IIRC, I also remember Iribe mentioning that they have been locked into specs for the CV1 for a while and that the Facebook purchase wouldn't change much, but it would likely have more of an influence on CV2 specs.

My bet is 1440p, but it's still anyone's guess since Oculus has been so tight-lipped.

For HL2 I had judder until I switched Rift to primary monitor, added '-refresh 75 -freq 75 -fps_max 75' to launch options and then started the game from Steam VR (in Steam, view>virtual reality beta). Those steps took away my judder and gave me a very smooth experience.

Those helped me too. Previously I was getting judder because the rift wasn't my primary monitor. When I set the rift as my primary monitor, half life won't run. I was getting a black screen.

It turns out I was missing one step. I had to set up steam VR, set DK as primary monitor, then run half life from inside steam VR for it to register. (don't forget the launch option)

No, is that the only way it works smoothly?



No, if the head tracking does not function you get dizzy almost instantly. It messes with my head real bad when the tracking is not working.
Yes. DK2 has to be primary monitor. Otherwise I think it won't run at 75hz.

Useful shortcut to know.
Windows key + arrow key.

That way you can send the selected window to the secondary monitor when your dk2 is the primary.

If your dk2 the primary monitor?
Yeah, primary monitor, -freq 75 -refresh 75 -fps_max 75, even have Aero disabled (W7) and the Rift as my only display. My game maintains 75fps or more, too, obviously.

I haven't tried running it through SteamVR though.

It's a very slight yet consistent stutter. It's a huge amount smoother Elite Dangerous, for example, just not as smooth as Quake, Quake 2, Suwako, Tuscany, etc.

Can you just use the oculus as a big screen or something similar? Just to play normal games on.
You can create a huge virtual display to play on, yes. I haven't tried it with games yet but having a huge curved display to watch YouTube and browse the web was pretty cool despite the screen door effect and low resolution. The app is called virtual desktop and is free.

Bummer that you have to change the OR to the main display to remove shudder, but least it's a work around for the time being, hopefully steam can fix with the next update.

Is there a short cut button in windows to swap displays around, as I thought all windows key+arrow key does was move the game to the next display and not actual swap displays from primary to secondary?

I think he's talking about playing non-VR games. Basically asking if you can use the headset as a display rather than go through VR drivers and VR software and whatnot.
