[REPORTED]VR Performance OB 2.5.6

[Caliboy42]

I like your quote, :thumbup:. Ok, two questions. Frames dropped in half... 80-40? 40-20? And list your system specs so we can see what’s different? Or list what is different? Sorry guys, I want to try and help ED figure this out and terms like half and almost don’t help at all... need to be more specific if you want to be part of the solution.

Sorry, but your posts are making no sense. We are talking about massive FPS hits (in certain circumstances) for a lot of users with no change in settings.

 

How are you ‘trying to help ED’ by suggesting that users need to look hard at their setups?

 

Just because you are not having a problem, doesn’t mean there isn’t one! This sort of thing has happened before, and is a very complicated issue. ED have found a solution previously, and I’m sure they will again.

[Hippo]

In terms of this thread, I’m not sure I understand what the problem is?

 

blah, blah, blah

 

Just saying...

 

I can see that you're new here, so I'm going to give you the benefit of the doubt and assume you're not just trolling.

 

I can’t tell the difference between 40 and 80 FPS anyway in VR

With the F-18, try taking off from a runway in a mission where you're reading 40 fps. You will notice that the HUD display looks distorted, and that there are distortions around the canopy frame. Why? Because ASW is kicking in: whilst the Rift continues to function at 80 fps - half of those frames are being interpolated. Sometimes this works well, and as in this case, sometimes it doesn't. At 80 fps you will not see this happen.

 

As a general rule, statements of this type (fps don't matter) instantly make me wary regarding a poster's credibility. Do you think if this was in any way plausible that HMD manufacturers would bother with refresh rates higher than 40 Hz, ASW, etc? Just think about it.

 

Are we asking too much from ED without checking our own systems?

Before you accuse others of not checking, perhaps you should follow your own advice and try to do what I did here:

In a simple mission with just the F-18 in it, there is a repeatable, verifiable increase in GPU utilisation. The only difference is the version of DCS I am running.

 

It just happens that of late I had been working on a number of simple missions with just an F-18 in them so noticed a decrease of around 10% - 15% fps (enough to tip me over from 80 fps to ASW kicking in and 40 fps) in those circumstances.

 

However, when I tried a mission with lots of ground objects, the fps drop was severe. Again, the only difference was in the DCS version:

 

https://forums.eagle.ru/showpost.php?p=4227381&postcount=100

 

Many people have reported similar experiences. I suspect that you will very likely notice a difference between 40 fps and 10 fps.

 

Perhaps you should make your testing and descriptions a bit more detailed yourself.

 

 

P.S. I did forget to include my PD (slap on the wrist for me) - it's 1.2.

Hi all

 

We are looking at FPS issues,

 

Lots of changes to lighting have been made in 2.5.6 you may find tweaking your settings does help in some cases.

 

With that said we are looking into optimisations and memory issues, when we have more news we will update you all with the patch notes.

 

thanks

Thanks for the update. Just a couple of things:

 

When I (and I'm sure most) report an fps drop here, I'm (we're) doing just that: reporting it - not complaining - I am fully aware it's a beta. If I were going to complain, it would be about how such a severe fps impact could make it through internal testing. ;).

 

For every subsequent update, if I continue to experience this issue I will continue to report it, on the assumption that it is helpful to do so.

 

Which settings in particular do you think will have the greatest effect?

Thank you. I see this often. However, in my personal experience, it has never made the slightest bit of difference, including here and now.

 

Can someone from ED please verify whether carrying out this step by users is a required part of the update process?

 

Surely ED wouldn't be so unprofessional as to not deal with this automatically as part of the update process?

 

I expect that ED will respond that it should never be necessary to do this, but am happy to be corrected.

Thanks BigNewy. I think most of us Sim vets are standing bye at this point.

 

I understand that there are a lot of people that have been here a lot longer than I have. What I don’t understand is why I, and others, am not having any FPS issues?....

 

At this point I think comments like these verge on trolling. Most of us on here seem to know what we are talking about (i.e know a trainwreck when we see one). There is no doubt there is a problem, and anyone who's been in the sim game for a few decades should know issues like these are not as simple as;

 

"I don't have the problem so it's not a problem".

 

Anyway, I too will continue to post and experiment, assuming it is helpful to do so. Thanks BigNewy, please ED keep us in the light on this.

The biggest FPS issues I’m seeing in VR is when there are any contrails or smoke, and when on our MP server it just kills my fps. The server mission we run has not changed since 2.5.5 when I was getting a perfectly acceptable frame rate.

 

Our mission does have a number of planes flying around in the con layer and since the latest updates it has become an issue, we have also noticed that since the latest patches that server use has dropped quit a bit. This I think also tells of the issues being seen by a lot of people, some who might not even be forum users.

At the moment I can nit link the performance loss to anny issue.

No mather what settings, no certain condition.

VR Performance is criticaly low.

 

Please ED Fix this as soon as possible.

[ib_]

check you pixel density. I changed mine from 2.5 (I think) to 1.8 and am at 40 FPS

[imaxx]

My pd is set to 1.0

Steam setting from 100% to 150% with same result.

 

FPS is about 40 but dropps much often to 20 incuding stutters.

Only think that changes was the ob version.

So it is broken since the 2.5.6 update

 

But it seems that this issue is adressed to ED

Thanks,

 

This is advice for installing that dodgy shaders mod. Deleting user shaders has never made any difference to me, and deleting the terrain shaders is probably not good advice outside of that mod.

[toutenglisse]

I'm noticing an impact on performances due to Lua functions that regularly check groups (like dead or alive).

 

On a Ka50 random escort task I'm building, 2 groups (about 5 to 10 units by group) at a time are checked for being dead or alive. If the functions are ran every 5 seconds, performances are impacted (zero critical usage but fps go to sawteeth instead of flat).

If the functions are ran every 30 seconds all is OK.

Here very short track about the TGP/Mav perf issue over Caucasus in VR.

 

I noticed something about this : here I just turn on TGP-Flir + Mav on displays, and fly turning around banking so both pointers are just below or on horizon. (in A10c)

 

On the first 360° around the perf are totally bad (less than 20 fps, issue accompanied by 4 cpu cores at 100% usage) every time pointers are upon mountains with forest area. During time pointers look to georgia west/sea direction, fps are good.

 

At the exact moment I finish the first 360° the perf are totally OK. The next 360° is perfect no issue.

 

If I restart this it happens again the same.

Just remember the extreme stuttering that occours with tv/ir cameras usage. Its totally unplayable now.

[Guppy]

BN, NL... here is a track that I hope you can do something with. My VR performance is very poor even with medium-high settings on my PC.

https://drive.google.com/file/d/1N2Km1O9q3GKH5NWcpBtE4I2Ip9feb-k0/view?usp=sharing

 

If I look out the window and see anything other than clear sky my frames are all over the place and there is stuttering when I move inside the pit. I'd call it a micro stutter, very noticable and all the way through the movement. It's almost like my tracking goes down to 15 frames a second, but DCS reports it high 40-90 but it is all over the place.

 

I use Bit Defender AV, but I turn it off while flying. I shut down all unnecessary processes like Logitech, Corsair, etc. with no change.

 

 

SPECS:

2080 TI OC'd

8700k @ 3.2

Scale in Steam VR is set at 1.5; DCS IPD = 1.0

Any word on from ED on bad VR performance?

 

Hi all.

 

I'm just wondering if there has been any word from ED regarding the current very bad VR performance after the 2.5.6 update?

 

I'm sure they know about it from all the threads, just wondering if any comment has been made?

 

Cheers.

Merged your post here in to the vr 2.5.6 thread.

 

We are working on memory leak issues and VR performance, you will start to see changes in the next patch and other patches going forward.

 

thanks

Thank you for the update BN.

 

I have some observations from my several hours of testing yesterday that I hope you find useful.

 

SUMMARY:

- Any time the terrain is within the FOV, regardless if the user can actually see the terrain, there is massive FPS loss/stuttering.

- If you imagine the cockpit is transparent and the user is looking down into the cockpit and the terrain is in the FOV there is impact to FPS.

- Fly inverted and look towards the seat, smooth FPS, but look up towards the top of the canopy at the ground and massive FPS loss/stuttering.

 

SETTINGS:

- everything to lowest possible in DCS

- PD set to 1.0 in game and in HPReverb

- What I've gathered is that any time the terrain is in the FOV of the user (including through the cockpit) the FPS drop and stuttering is huge.

 

STEPS TO REPRODUCE:

- Fly level looking out the canopy towards terrain, move your head around - FPS drop/stuttering

- Fly level and look down at your seat and L/R consoles - FPS drop/stuttering

- Fly vertical, 90 degrees towards the sky and do not have any terrain in your FOV - FPS is smooth

- Fly inverted and level and look down at the terrain, through the canopy - FPS drop/stuttering

- Fly inverted and look down towards your seat and L/R consoles - FPS is smooth.

 

Let me know if there is anything else you would like me to test or look into. I'm happy to help.

I've also implemented the changes below and have the exact same behavior. Something is up with the terrain in VR.

I use a reverb also and I tried beta today and it ran horrible in multiplayer but single player i could fly instant action without much issue but still not as good as release version. I went back to release and flew in multiplayer for 2 hours with no issues. My settings are not low either. I hope they fix beta for VR as I really want to take advantage of the newest improvements.

 

The only issue is download speeds when updating back and forth from beta. The speeds were in the low single digits but if i go download the installer from the website and run the download for new install i get 30-70mb/sec.

Do two installs, one for the beta one for live...

[sirrah]

Any of you guys tried all this yet?

 

 

All these positive replies on YT made me quite hopeful. But unfortunately none of these tricks gave me any fps increase whatsoever. I tested after each "install", but couldn't see the slightest improvement (not even with the shaders mod).

 

Tested in F-16C instant action PG cold and dark and my fps just keeps swinging around 26 when looking around inside the cockpit.

 

I was just wondering if I'm the only one not seeing framerate improvement by this 2.5.6 shader mod..

[speed-of-heat]

yes.. you gain back some FPS, but, not as much as you loose in going to 2.5.6
