Tomcat on a busy carrier. I have foveated rendering enabled though, maybe thats the bug. Will try without.

 

Just to pin the problem down I would try different locations with different aircraft. Not that it helps you with the F14 though. I am absouloutly happy with every aircraft I own except for the apache. So, for me that means currently repro off for the apache and on for every other aircraft. 

But the problem sounds very similar to mine. My GPU usage went down to 35% when the FPS drops to 20 and it won't come back again. Only when I change aircraft and wait about a minute it'll stabilize at 45 or 30 fps.

Another thing I don't think I've seen mentioned.  For me at least, the clouds are a lot let jagged than I recall. Especially the F-16 quickstart/take off Caucuses mission.

Anybody got the OBS plugin to work by any chance? I am getting a black screen inside OBS. No idea what to do.

Try streamlabs instead. Its OBS but works.

Hey Guys, I am running NIS on what do you recommend for the sharpness setting and should anamorphic be on or off?

Thanks

Any 3080/3090 G2 user who has configured The OpenXR Toolkit to get some decent performance and good visuals?

I just installed it, am used to Reshade + foveated VR Performance kit. No idea where to start with all the new settings and since this thread is already 21 pages long I hope somebody has a decent reference.

 

Much apreciated

Unless something has changed, I seem to recall reading that it will not work with Reshade. I have confirmed it will work with Simplex shaders and latest 3DMigato.

I've seen similar as well when reprojection is turned on, I've had it locked down to 30fps even frametimes have been 18ms (55fps). It would be worth raising that one with the devs on discord.

Not only that, but in my case enabling motion reprojection causes my GPU frametimes to increase. I don't know if this should be the expected behaviour with OpenXR, but in my system, enabling SteamVR's motion reprojection doesn't impact frametimes at all.

I have continued my testing with many aircrafts/scenarios combinations and the result is always the same, even in the DCS menu screen. Examples with average APP frametimes:

F18 Caucasus free flight:

• MR disabled:
  • CPU: 11ms
  • GPU: 16ms
  • Render Refresh Rate: 55hz
     
• MR enabled:
  • CPU: 11ms
  • GPU: 21ms
  • Render Refresh Rate: 30hz

DCS menu:

• MR disabled:
  • CPU: 2.5ms
  • GPU: 11ms
  • Render Refresh Rate: 90hz
     
• MR enabled:
  • CPU: 2.5ms
  • GPU: 14ms
  • Render Refresh Rate: 45hz

That's interesting, something doesn't quite look like it's tieing up 16ms is 60hz.

However the 21ms is about 48hz and motion reprojection is triggered to be locked down to 30hz, this is expected behaviour with WMR reprojection as it needs a minimum of around 55% of refresh rate (50fps give or take) in order to work.

Because you are using openxr it steps down to 30hz and continues to reproject, if you were using steamvr then the reprojection would have disabled itself and it would be very stuttery.

I think the same might be happening on your menus, reprojection has a slight overhead cost and that takes away GPU cycles in the background. With reprojection off you're only just achieving refresh rate target of 11ms, which with a ms or so less for overhead will knock you down to the 45hz bracket.

It's curious that it's showing 14ms and 45hz, that could be a function of the hysteresis and averaging of the frametime counter.

For reference I always have 90fps in the menu and frametimes of around 6-7ms. 11ms in menu seems very high, what GPU are you running?

Yes I know. Have the Simplex shaders running at the moment.

Looking for somebody with similar hardware and who has already played around with settings like anamorphic, size, sharpness, foveated settings, motion reprojection etc. Just to get to some sort of baseline which I can copy and start playing around from there on forward.

my rig specs are in my sig.

Been flying the Apache for the last 3 days with the OpenXR and Toolkit, and sharing my experiences.

- have the full monty, opencomposite v0.6.2 and the toolkit 1.0.4.
- within the toolkit, I do NOT have upscaling enabled.  just going with the 100% for now....
- in the toolkit, I have bumped up the world scale to 120%   My M-4 now looks almost life size.  Don't ask my why I know that....   
- For OpenXR, my custom render scale is 150%, and MR is "always on".  Yes, I'm using MR, but read on...  

I've cycled through all of the maps, just flying the Apache.  Using the default SP, hot ramp start for the flights.

For Caucasus, always a solid 30fps, with an occassional bump up to 45, (but very occassional).  As noted in this thread, with the Toolkit, 30fps is the new 45!

Persian Gulf, 90% of the time I'm at 45fps, and the occassional drop to 30.

NTTR, similar to my Persian Gulf measures.

Marianas, most all of the time at 30fps.  (I also had fun landing my chopper on the carrier task force that was operating near the island chain).

Syria, taking off from Incirlik at 30, but I did have a few dips to 22.5.  But the majority of the time, I managed 30 over the cities.

Syria seemed to be the most taxing with the Apache, followed by the Mariana's.

I've left MR on, and am very happy with the 30fps.  It just looks great. Rather, my flights are BUTTER  SMOOTH!!!  Plus, all of the color tweaks you can do with the Toolkit, (it's a bonus).  With OpenXR at 150%, the terrain and graphics just look stunning and clear.  I'm sure I could throttle back from the 150%, to get higher fps, by why?  30fps via the toolkit is just rock solid and looks great.  Most of my DCS in game settings are high, and shadows at medium.

The one thing we really need with the Apache.  A mod to fix that d*mn rotor blade distortions! 

I'm going back to flying, it just looks awesome, and I want to have some fun.

Thanks mates. I see some good improvement in the cockpit

[Thanatos31]

HI Team - 

It definately helps - but I dont seem to get the Foveated Rendering option in the menue.

I have an AMD RX6700 with DX12 - that should work shouldnt it? OR did I miss something ? 

• AMD RX 6000 series, with DX12 only.

I think someone mentioned a few pages ago, that FFR doesn't work with AMD cards (yet). But I could be wrong. 

 

Yes, page 20 answered by @nikoel

Makes sense, the thing is that SteamVR's MR doesn't seem to have that overhead cost, as FPS keep exactly the same when I disable/enable it (with SteamVR I can disable/eneable it in real time via its video menu, so it's pretty easy to spot the difference). 

I've still got my trusty 1080ti. I need as much VRAM as I can get for 3D modeling stuff, so I have been reticent to upgrade and loose VRAM (the 3090 is the only option but, its price is definitely not something I'm willing to pay for a GPU ) 

[Thanatos31]

oh snap! missed that. I thought this was added as it was mentioned in their release

I have noticed that the OXR motion repro seems to "learn."

If I start in FA-18, Ready on The ramp/Caucuses and sit the for a bit just looking around, I can see the jelly effect panning view side to side while looking a CDU etc.

Continues while I taxi, but once airborne it dissipates and the DCS fps counter shows a steady 45fps. No terrain jitter, no more jelly glancing around the cockpit.

 

Considering how early in "beta" we are with this... the future looks bright. (crystal clear)

Try the following: if not done already, run a repair (slow method and delete extra files if it finds any). Then put your headset on the desk, close everything. WMR, any openxr tasks in the task manager and of course steam. 

Then (before putting on your headset on), start DCS. Put your headset on again as soon as the DCS load screen starts. Notice, that the WMR menu will open and close twice. That does the trick for me at least.

For me now with a 6900xt and 3800xt this has been a monumental shift in the right direction, unlocking the true potential of the gpu especially. Big thumbs up to @nikoelfor bringing this all to our attention and getting the discussion rolling.

I’ve been resting in sp and mp and tweaking and made a few observations. Out of interest I wanted to see what dcs looks like in vr all maxed out with all eye candy and forget performance, just to see what may be possible. To my utter amazement, not only did it look amazing it was also flyable. I set custom resolution in openXR to 120%, dropped msaa and af altogether as they are unnecessary at this resolution and flew an sp mission with 4 apaches achieving a solid and smooth 45fps. Never did I imagine dcs could look this good. I’ve been flying helicopters for 25 years professionally and spend a lot of time in level d sims for work, and man this looks waaaaay better than our sims. It’s the closest to real flying I’ve seen in a sim. For whatever reason it seems like steamvr was really crippling us g2 users and or 6900xt users. 
 

mp is a bit different but still amazing results for me. I had to drop resolution to 95%, shadows down and it rest all maxed.

Apologies for this repost. (inadvertently delete it!

Getting this error when i try start DCS with OPENXR. Seems to be looking for the open-composite-acc folder. I choose the option to manually install the 3 files, and did nothing with the openn-composite-acc package. Is this correct. Any help welcome.
