Oculus Rift and DCS World Discussion

[Frusheen]

I think in the long run we will require GameworksVR and LiquidVR features to be implemented by Eagle Dynamics. It's hard to see how any current generation card will run at 90fps/eye for vive or rift without the help of a second card.

Has anyone had problems with mouse behaviour in VR since DCS 1.5.xx

 

In VR ... once the mouse leaves the window it is out of sight and gets lost.

 

If you click accidentally click outside the DCS window it loses focus and you can't even see the mouse passing over the DCS window.

 

===

 

Frusheen ... can't wait to finally open Nevada. I think that tweaking setting will take us a long way optimising for VR. I hope that all the LUA setting available in DCS 1.5.xx remain for DCS 2.xx. I noticed that without a terrain installed in 2.0 I am missing terrain.cfg.lua and more generally the Bazar/Terrain directory. That particular file is where I was able to optimise VR peromance the most ... for my purposes.

Oculus in 2.0

 

Hello all....

 

I have been active with sims since Mig Ally, but here since Lock-on...

 

I am currently using 1.5 and 2.0.

 

I havent testet on the new version af 1.5 yet. But before the update I could run the sim, with a steady FPS at 75 with Oculus. Now in 2.0 I cant get past 38 no matter what I do, and what settings I use.:helpsmilie:

 

On the other hand, I dont get a bad hit in FPS when I turn up the settings either, it will max be 5 FPS or so.

 

This leads me to think, that there might be some kind of bottleneck from the CPU side...

 

Any other Oculus user in here, that got some kind of knowledge, and would like to share?

I'm interested to see what you come up with. I did notice that turning off civil traffic is not actually removing the traffic. I'm sure that is hurting frames for me. I'm only intersted in low to medium level Helicopter flying in DCS so I'm going to notice lower settings more than some of the high fixed wing flyers.

My testing in VR is showing that for chopper use you can radically reduce the VISIB DISTANCE a lot more than if you are flying aircraft at a medium level. There are also a lot of details that you can forgo in VR due to the compromised resolution of the HMD.

 

What I found is that a lot of elements could be removed without affecting the feel of the sim. It does take lua mods to make most of these changes. The main thing is to focus attention on stuff you can actually see in VR. you can't zoom in VR so a lot of things at range can be removed without people really noticing.

 

There are specific objects that can be FOCUSED ON because these things you DO notice.

 

Textures

• road (increase range) at least 50km before fading
  
• rivers and lakes (increase range) at least 50km before fading
  

Objects

• Large unique structures (increase range)
  

 

There are specific objects that can have a REDUCED FOCUS because these things you don't notice notice or they are so small in size that they are just blurry most of the time

 

Textures

• short range field textures (totally remove rendering pass)
  
• short range village and town ground textures (totally remove rendering pass)
  

*Note - Long range textures still show up for long distances. You get town geometry closeup and town textures long distance.

 

Objects

• forests (remove - this one is shame because they look good BUT THEY KILL FPS) :noexpression: Districts come with their own trees so you still get heaps of trees. It is a compromise.
  
• ground units (decrease range but increase visibility LARGE)
  
• street light poles (remove)
  
• electricity towers (reduced range)
  
• wire visibility (increase range slightly)
  
• traffic (low and reduce range)
  
• districts (reduce number of districts rendered but increase range)
  
• tree visibility (set to zero) Special case of trees explained below.
  

 

Trees in 1.5.xx in DCS are weird. There are many types of tree object and each type has it's own settings. Trees also destroy the framerate the most of any object in 1.5.xx. Forests are just the worst. It is worth knowing how trees work in DCS in more detail. I do know that by tweaking some lua settings you can choose to render only certain tree groups for a given visibility range. I am still not sure how this is achieved ... I am not sure which settings are make this possible.

 

Work will focus on DCS 2.0 when I finally get to run it.

One of the major problem with VR is fact that you cant spot targets on ground or at least it is very hard to do that.

 

People playing with blue and red markings over target to be visible. This is in contradiction by realism and immersion which VR brings.

 

Is it possible to make this targets more visible in VR to be able to fly without this markings on or on multiplayer servers without this markings?

Someone wanted to know about A/A refueling with the Oculus. I gave it a go after not even attempting it for a hundred years (save the commetary, pls):

The Oculus should make it very easy to do, and with a bit of practice, my rusty skills will be polished.

Does anyone have any advice for making the radio commands easier to access while using the Oculus? It's tough to say the least - they are really hard to read :/

I had a radio mod in 1.2 that moved the menu to the middle of the screen and you could also increase the size of the txt. I'll see can I find a link.

[Frusheen]

Here it is. PeterPs clickable radio mod. Not sure if it'll work with 1.5/2.0

Thank you, Frusheen...What we really need is for ED to do the radio commands properly and give some love to us VR users. Bigger text, closer to the middle, slaved to head movement would be ideal.

Edited December 1, 2015 by DerekSpeare

It is a shame that terrain.cfg.lua is the ACTUAL file that ED choose to encrypt for their content protection system for Terrains. It means that the lua customisations for VR possible with the DCS 1.5.xx and the Caucausus map are not possible for DCS 2.xx and Nevada.

 

It is a bit disappointing. I don't think it is a deliberate attempt by ED to stop customisation ... just an unlucky side effect of their content protection scheme.

What is awesome is that the mouse behaviour is fixed in DCS 2.0. Mouse stays in the window until you ALT-TAB.

Agreed. Although ideally I'd prefer to have the radio working well with voice attack. I hope the Huey will be added to this soon:

Does anyone know of a link that shows the radio comms menu tree and each F-Key's options and suboptions? I may have to resort to memorizing everything :D

You should buy "Voice activated Command" like I have and then you just use you voice to activate anything in the radio. A guy called fish mapped out all the radio commands for the A10C, but you can setup your own and its not hard to use.

I hope at sometime someone can make a map for VR where there is no judder. This is possible now that edge is out, it just requires some who wants to do it and I'm sure it will be a big hit for VR fans.

OK, finally gotten around to trying out the DK2 with Nevada.

 

It really is a wonderful thing. The res of the DK2 interferes a little with enjoying the scenery as much as I would like to, but the immersion is just terrific.

 

It is worth noting though that I manage to avoid getting motion sickness from the rift, even with a low framerate, so I have been able to turn up all my settings to max. I've just learned to "defocus" my eyes whenever I move my head, which stops any nausea developing, and then"refocus" when I've stopped moving.

 

I can't wait for the consumer level of VR HMD to come out - although I think I will definitely need to grab a second 980 for SLI to properly enjoy the experience...

 

Cheers,

You don't need to set all setting to high when using the Rift. You won't notice when some of the settings are tuned down in the Rift because of the Rifts resolution. But it makes a big difference to performance if you have them all set to high. You should turn Visibility to medium, Water to low and Shadow off. You will see a big increase in performance if you do this and it will still look just as good in the Rift. Infact, I think leaving shadows ON makes things look worse.

I'll try some of them out, but if it means I don't see shadows then they're staying nice and high. Shadows add depth massively in my most humble of opinions.

 

Guess it's down to personal preference.

Fair enough for DCS, but my main want for SLI is the myriad of other VR experiences I plan to enjoy :)

 

At least, that's based on the info from Nvidia here - http://nvidianews.nvidia.com/news/nvidia-vr-platforms-deliver-massive-performance-boost-for-virtual-reality

 

Thanks for the link.

That thread is an interesting read.

 

It seems that there is a real mix between those who find SLI worls well and those who just cannot get it working.

 

Seems to be not just for DCS too, but for many other games.

 

I've never tried SLI before and was only really interested for the VR boosts it is supposed to be bringing (one card per eye rendering).

 

I'm in no rush though and will see where the tech goes in the future when consumer VR HMD are released...

Sometimes SL1 syncing creates stutter, which is the last thing that VR needs. Since NVidia, and AMD are working closely with VR devs, this issues could become a non-issue at some point. Up to this point, I've only configured an SL1 system once, and found it better just to have the best single gpu possible.

 

Hopefully the next generation gpus will be powerful enough that SL1 won't be required for VR, as a single gpu is much cheaper than buying two, along with a compatible motherboard.

Don't confuse sli and VRsli. They are very different things. VRsli is part of a package of measures being introduced by the big two card manufacturers. Google gameworksVR and liquidVR if you want to know more.
