Valve/HTC Vive Discussion

[S3NTRY11]

Are we sure there isn't an FPS limit preventing DCS from going past 60 FPS? It seems unlikely to me that a 980Ti won't be able to hit 90 FPS even once in a while on the lowest settings.

My R9 390X hits 90, so I don't see why a 980ti couldn't.

Guys, when lunching games with the Vive, try holding down ALT key while launching the game. I think it works on steam. It selects the lowest resolution for a single occurrence.

Might speed up things a bit.

[liq3]

So I've noticed some odd stuff. Normal = 1080p on a normal monitor. Setting are all low for both, including flat shadows.

 

1. I get 60 fps max in menu in VR. 200fps normally.

2. Warthog, single mission Runway start. 60fps in VR, 120 to 150fps normally. The really odd thing about this though, is it only uses 25% CPU in VR but is using 40% normal.

3. It's (probably) a CPU bottleneck in VR. Both MSI Afterburner and SteamVR's frame timing confirm this.

4. If I started the game without first starting SteamVR, the framerate seemed to be unlocked and would fluctuate instead of staying around 60fps.

Dudes....

 

With the runtime 1.3 for Oculus, I can run all max, 90 fps, no stutter or lag....

I dont know with the vive, I would go for Oculus, if I was you

A bit bulky, but seems like a way to have more of tracked walking space:

Hey guys ,

 

I made the concious decision to go for the Vive as it appears to be the marginally better and more complete kit compared to the Oculus overall.

Awaiting the kit to arrive any decade now.

I'll be sticking to my decision, but browsing through this thread it does make me slightly nervous in terms of what to expect with DCS when I read this stuff about low framerates etc.

 

I am no expert in this area at all (at least not yet). Will this be a matter of ED dev putting in some additional effort to improve their Vive support

(assuming they focussed on the Rift first), or are there more fundamental issues at hand here?

 

Appreciate your informed opinions on this.

 

Cheers

You wont go to far wrong by buying the Vive headset, as it is very good, and you can have room scale controllers now.

BUT... if your primarily a flight simmer the Rift could be the better choice.

The Rift has more refined Displays/Optics

The Rift is likely to be more comfortable for more people for longer periods of time.

The Rift is much cheaper for flight simmers.

The Rift ATW software appears to be working better than the Vive equivalent.

Has anyone else had severe performance issues turn up for the vive OR the oculus in the past 3 days? Previously I was running a DK2 and it was playable, I didn't measure my FPS but it was most likely above 60. Not perfect for seamless VR but playable.

 

I visited a friend who now has a vive and we got DCS going, this was on the 11th April, and it was playable in the SU25. However the next day he bought FC3 and tried out the f15-c (loading the quick mission -> intercept misson) and texted that it was unplayable.

 

Not quite believing him I decided to install fraps and check my FPS. Lo and behold yesterday on the 12th I was getting 45fps average, 60-70 when looking up at the sky, and when the TU-22 drops it's dozen or so bombs it went all the way down to 7fps. Crazy. A few days ago this was not happening. (I'm running a 980gtx).

 

One tell-tale sign is that while I am using a DK2, I noticed the blue chaperone lines appearing in the cockpit, and sometimes the image would flicker to the white blank stage. I think there was a valve update to steamVR, and it's blending between two scenes that need to be rendered in real-time.

 

Has anyone else noticed this drop in performance and insertion of chaperone features?

Sounds like you are still using steamVR to run the dk2 which makes no sense. I posted a reply in the Oculus thread with something for you to try.

[Shabi]

I tried Frusheen's suggestions in the other thread, mainly to install Oculus Home (should have occurred to me to try it, I guess you get tunnel vision in Steam). Performance is fixed, for the DK2 anyway.

 

So judging from that experience and my friend's comments RE the vive and steamVR, I think there are some bugs to be squashed in the way they play with DCS.

I always have severe stutters(not related to head movement) when over towns and/or other planes around. Borderline playable right now. Funny thing is graphics options make no difference whatesoever and according to my performance tools my graphix card only 60% used and cpu only 1 core out of 8 used.

FWIW

 

Yesterday I updated to 1.3 supported DCS.

I ran a mission and there was terrible judder DK2 running under SteamVR ( I still had 0.8 loaded)

Installed Oculus 1.3. Everything running way smoother significantly better than it has in the last 20 months.

I believe at the moment DCS is much better optimized for Oculus than Vive.

I have both on Pre-Order.

I don't think it has anything to do with dcs. It is most likely down to ATW.

[NakedSquirrel]

The VIVE uses reprojection which is its name for ATW. Is that not working as well as ATW or does it just not work on DK2?

 

The thing I'm curious to hear about with ATW vs reprojection is whether reprojection works below 45fps or not.

 

I was thinking re projection was a completely different technology, but after watching presentations on it, it is almost identical to ATW,but all of the vive presentations talk about a magic 45 or 90 fps to keep any ghosting or anomalies from becoming too distracting or disorienting. I don't know if that means they didn't program it to work below 45fps or that it just doesn't work as nicely.

[thetinguy]

So I've been dealing with a new issue. Everytime I start dcs, the menu is not facing my monitor. So I end up having to look to the right or behind me. Anyone know any fixes?

[AstroEma]

yep, launch Steam in the Vive headset (click on the system button on the controller once) and look for the settings (up right corner) then VR Settings, General VR Settings.

There should be a line which if you click on it will reset the seated position. (Click here to reset seated position).

 

Other way to do it, press 5 key in the numpad :D

Thanks! I also discovered when doing the seated setup, DCS will use the direction of the headset when calibrating the floor. So I made sure my headset was facing my monitor when calibrating the floor and the issue was resolved.

[Magic_Carpet]

I'll try to work through some of the performance issues myself hopefully starting tonight.

I've been very busy the last couple days.

 

DCS + Vive and DCS in VR does need some improvements. I've played with the HTC Vive using other applications and demo's which are optimized for the vive, and it is an incredible experience. Give the Eagle Dynamics Team some time to optimize and work through these performance and other issues. Keep in mind we're on the very edge of a new frontier.

 

 

Hi all,

 

I made some test this morning with the Vive. Everything work flawlessly between 45 fps and 90 fps until some AI appear. One or two and the stuttering begins and start to degrade the experience.

It seems the reprojection tool has some difficulties to keep up in those condition.

[Warthog_Farmer]

This thread is too long to read... But I've just jumped over from the Rift thread. I am a CV1 user and the Rift head tracking never falters. It is always smooth and accurate.

 

However - the image projected after the head tracking element will stutter when looking at or in the direction of towns. Take Batumi as the example - look north and it will reduce to 40fps and stutter. Look anywhere else and a solid 90 with smooth motion.

 

If your head tracking is still smooth as butter and it's only the DCS generated world that's stuttering then don't think your kit is any further behind than the Rift with ATW. We're all in the same boat waiting on core engine optimisation for better, consistent frame rates =[

Yes I saw that too. No explanation where it is from though it looks like it's DCS, the Mirage perhaps.

[montify]

Have a Vive now, you can read everything way much better than with the DK2.

 

But i only get 30fps?????

:helpsmilie:

[montify]

When i enable V-Sync i got 45fps - with low settings. But 45fps are enough to run smooth! :)

[Kirin]

Tested DCS with the Vive for some days now.

 

Performance is ok but I get a periodic micro-judder every 5 sec or so. More visible when I turn my head. Running all low/medium does not make a difference. When running on high I get constant judders as expected. Anyone got a tip? V-Sync On does introduce a lot more juddering. Disabled Thread optimizin already in the NVidia panel.

 

Gauges and HUD are perfectly readable in the sweet spot - which is rather small tho. It's interesting experience how focus switches from looking out in the far/HUD and looking at the instrument panel. The cockpit feels kinda smallish tho. Everything got a toy feel to it.

 

 

My specs:

i76700k, GTX970

That doesn't sound good. So it looks unrealistic, like tilt-shift effect? :)
