Oculus Rift and DCS World Discussion

Thanks PiedDroit! That’s why I love this place… someone always has helpful answers!

Welcome :thumbup:

@Carabassa and rjetster1:

I think the value for the IPD is the eye_shift parameter in Stereo.lua (one for each eye).

You should try different (smaller) values to see if it has an impact on scaling.

EDIT: in \DCS World OpenBeta\Config\MonitorSetup

I still think it gives you a good feel as to what it's like in a cockpit, regardless of making things look a bit smaller. I did find the A10C quite small though compared to the BlackShark and the World War 2 Aircraft. Does anyone know the reason for this?

I wish there was a setting like in Flyinside FSX where you can actually adjust the size of the cockpit using keyboard keys, but the CV1 is going to get 2 screens and an adjuster on the device for ipd, so I'm not sure if that will help to increase the size of the cockpits.

What will happen if I make my ipd smaller in the rift setting? Will it make the A10C cockpit look bigger I wonder?

Maybe if they gave use the zoom function in the Rift it would make the cockpits appear larger? I'm thinking "Peter P neck mod" and the zoom function for the DK2. Either that or does anyone know if there is a Mod that can make the cockpits appear larger?

F15 from FC3. Custom mission clear weather at 12 AM. Starting from random airport.

Every else default.

Thank you for your answer.

So 150 FPS when doing free flight on the F15. But on the Intercept mission, it immediately drops to 75.

So it is not only me?

Wrong IPD setting will only make you sick, but it will not make things smaller or bigger as far as i'm aware. Nothing we can do about it on the user side.

This is what I thought as well, it will only make it harder for your eyes to merge the image but the scale should be the same.

So what about what PiedDroit said? Where you change it in the DCS config settings? Would that make a difference to the size of the cockpit? The BlackShark appears fine to be fine, but the A10C looks a bit on the small size.. Why is that?

The main thing that the ipd in the rift does is to make it so that you can look straight ahead and have the images in the rift in the right place.

If not then you need to go cross eyed to some extent. So its not really scaling just moving each view in and out to match our eye position when relaxed and looking forward.

I know people as large as I am that have different ipd's. Mine is quite wide, some are smaller but they are not going to see a larger cockpit than I do in relation to themselves because they are the same size as me, just a different ipd.

Anyhow, that is the intention of setting the ipd in the rift. Camera settings that the game has could do something different I suppose. It might have a pilot model that it is scaling, i.e. change the eyes and the pilot scale also changes. Dont know but it should not necessarily scale your environment.

Just to add, I dont know if modifying those parameters will change the scale as I have never tried. Others say it might so I am not saying they are wrong, just pointing out that this would be a glitch in the graphics engine and not represent what actually happens with humans.

Okay, I'm back from doing a bit of testing. I found there isn't anything wrong with the cockpits size since all you have to do is lean forward a little in the Rift and hit the re-center key you have set for yourself in-game. My center key is number 5 by default. Doing this then places you further back in the Cockpit if you prefer. You can even adjust how you are sat by ducking your head slightly and hitting re-center key.

I also tried snap views and they seem to work and even allow you to still look around in the Rift. This I think will come in real handy when wanting to look at the CDU. I'm going to check later to see if it's easy to press the CDU buttons once in snap view.

Changing the settings in DCS to the ipd settings I have in the DK2 Config utility has worked a treat for me.

Take a look at this link rather then me explain it. This guy gave me my ipd setting to use in the DCS settings and I see things much clearer. Remember to save the original file though if you want to give it a go.

From the testing I am doing right now ... the settings in Config/MonitorSetup/Stereo.lua have no effect in DCS 1.5 BETA VR mode. I am throwing some wild values into these settings and nothing looks different.

What are you guys doing different to me?

* Update - It doesn't work. I'm calling BS on this one*

Same here. No difference seen when modifying the stereo.lua file.

Well, it does, I can confirm first hand.

I think you are confusing IPD in the rift (optics) and IPD in-game (rendering, the one I'm talking about)

Try creating a copy of Stereo.lua in your Saved Games\DCS.openbeta\Config\MonitorSetup\, rename the config "Stereo2".

The DCS graphic engine can use this value, here are the screenshots (non-open beta, values 0.02 and 0.16):

In the open-beta I can't get a view like this so I can't tell if it works (last screenshot).

Pied, that is what I would expect to see. There is greater separation in one image than in the other but I don't see any noticeable difference in scale of the image.

Because of the greater separation there is more FOV in one image but the cockpit remains the same size.

Yep, the greater separation won't affect the size of what you see (you need a zoom for that) but will affect how you perceive the object size around you (on the second picture your brain will assume the cockpit is very small because the left eye is tucked on the left window and the right eye is tucked on the right window.

When I tried extreme scaling value in FSX I had the feeling to be in a toy aircraft cockpit I was wearing like a helmet.

So quick question....really enjoying flying with the rift in Open Beta. So when I've been recording the footage it records what on the screen. I'd like to have it record the two-eye view so I can watch it in 3d later like other oculus rift footage. How do people do that?

I currently use X-split to record footage since it lets me layer things like...but I'm open to using another application if it'll work.

Well, it does, I can confirm first hand.

There was no MonitorSetup folder in my openbeta's Saved Games folder. So I created on and stuck STEREO2.LUA file. Interestingly, I now see two "STEREO" (no #2 at the end) in my setup.

Changing the values didn't do much for me. But I will continue to test. Will try to figure out why I see two STEREO lua files.

@hansangb- I think the changes are subtle. I can see the gauges clearer then I could before even making out what some of the digits are in the HUD of the A10C. Choosing different number must make a difference because those number aren't there for no reason. I prefer to have my ipd set in the game the same as it is in my rift config utility.

From memory, inside the file is the name 'stereo' that you need to set to 'stereo2'. You need to set the value there as the game GUI doesnt show you the value based on the file name.

EG, the existing stereo, you could change the file name to 'abcd' and it will still show stereo based on the value inside the file.

Just hold on a few days and we will have DCS 1.5 with improved Oculus support. Nobody knows what the improvements will be though. But fortunately they seem to be getting this VR thing quite seriously.

 

On the refresh rate topic, the Rift uses a technique to reduce blurriness, called 'low persistence', consisting on flashing the frames a few miliseconds instead of just presenting the frame all the time until next frame arrives, that needs high refresh rates for the flickering not to be noticeable.

That said, I'm with you. I'd accept the blurriness of 60Hz without low persistence. It may not fall on the VR definition as it's being defined nowadays, but still is just such a natural way of interacting with the computer compared to trackir or whatever else that it's still desirable.

i have recently downloaded 1.5 and upgraded to oculus 0.7, and still i get the appearance to be not smooth (juddering) as i turn my head. while on the second mnito attached it is perfectly smooth, Why?

a forum said that dcs relys on cpu not gpu for grafics.

also, please help i need to improve it. please help!!!

That makes sense. I'll play with the files to see what's going on. @crunchy, I *thought* the dials looked sharper as well. But I figured it was due to placebo effect. But I will do some more testing to see.

Also, the eye_shift is the IPD, or is that the dxview?

Thanks

We don't know your HW, so it just may be that you don't have enough HW. But try the free flight first. As soon as you have AI involved, the frame rate drops to 75FPS. Also, go back one or two pages and see the settings that can help with minimizing juddering.

Anyone else, when using the dk2, not being able to see/use the kneeboard?

And the F10 map view only shows the map icons and GUI, the map itself is all grey.

It's the same for all my modules :-/

No showstopper but annoying:-P
