[REPORTED]VR Performance OB 2.5.6

[Ramires]

I've performance drops when switching from an aircraft to an A-10. Stutters in the Cockpit View especially when Looking downwards to the HSI...

[Kayos]

My FPS is down by about 26 fps. Hopefully this gets fixed this Wednesday.

It's not a bug, it's a feature.

 

 

(Possibly.)

same here a good 15fps drop in beta 2.5.6,

when playing exact exact same mission on beta 2.5.5.

Not playable so reverting back.

 

Any advice on how to go about that without having to redo everything?

 

Also, I have been enjoying the F/A-18C a lot lately, is going back to 2.5.5 stable going to take away from the experience (as in, are all its latest upgrades available in 2.5.5?)

 

The biggest regret will be not being able to do online multiplayer anymore, but I can't really accept the state in 2.5.6, especially running on a 5GHZ 9700k, 2080ti, SSD and 32GB@3200MHz RAM...

 

My plan is to:

 

1. deactivate any mod I have (thanks to OvGME)
   
2. run a repair/clean
   
3. downgrade to 2.5.5
   
4. run a repair/clean
   
5. reinstall mods (thanks OvGME)
   
6. ???
   
7. Profit.
   

This should also let me use the new nvidia drivers, until ED sorts out 2.5.6.

The clean/repair and downgrade steps will be done via skatezilla's excellent DCS Updater utility, yes.

 

I was more concerned about things to look out for, like: loosing keybinds/settings, modules that become less/non functional (F18, F16), not having the new Ka50 and A10C cockpits anymore (although admittedly I liked the previous A10C cockpit better, especially with Ricardo's textures) and other problems that I might fail to foresee...

[speed-of-heat]

keybinds are stored in your user\savedgames\dcs directory

[imacken]

keybinds are stored in your user\savedgames\dcs directory

 

Just to add to that, it'll be in \Users\xxx\Saved Games\DCS.openbeta\Config\Input in your case as you were on the beta, I think.

[SPAS79]

Given that for some reason I have an openbeta install in a ..\Saved Games\DCS\... folder, I was worried of losing all my keybindings (which I am in the process to migrating to Joystick Gremlin, but I'm far from complete...)

 

 

I guess I'll just copy them over.

This is easy to do without harm using the DSC updater... I use often use to switch and test between versions See full guide here. https://forums.eagle.ru/showthread.php?t=114030

 

PS, anyone say what the porpose of 2.5.6 was? It just seems to have over saturated the shaders and and nerfed performance :( I don't see any benefit worth the hit?

By the way not sure if this helps in ED's DCS betaperformance debugging but I noticed only 50% max usage of my gtx1080ti and only 40% cpu usage in 2.5.6?!!

Hi all

 

When I have news to share I will share it. When I see progress being made internally I will pass it on to you all.

 

Ranting and off topic post will be removed, as mentioned before.

 

Thanks

Happens the same, my GPU don´t surpass 50% utilization (52 to 55 ºC maximum, on 2080ti), setting with a PD of 202% and many other graphics options enabled.

ASW? CPU - what are the individual cores doing?

 

Sorry if I'm telling you what you already know, but it's impossible to ascertain someone's level of knowledge. Check the screenshot on my post:

With VR, and my Rift-S, I'm only going to run at 80 fps OR 40 fps (ASW). This means that I will get the corresponding % util according to those frame rates. See how my GPU util is initially just below 100% when I run at 80fps, and dips to around 60% intermittently, then stays there as I get closer to the aerodrome and the GPU needs to work harder (ASW kicks in and 40fps)?

 

Also, see how it's CPU core 12 that I've selected to monitor? It's that core that does most of the work. You need to look at individiual cores and not overall CPU util, which will be an average. It could be that one of your cores is running high and that's the bottleneck.

 

What's probably happening in your case, is that ASW is limiting your fps to 40, where your system would be capable of managing more. Your system doesn't require very high CPU/GPU util to maintain 40 fps, but cannot manage the performance to maintain 80 fps, so is capped by ASW to 40.

 

Upshot: if EITHER the CPU (a specific core) or GPU approach 100% util (at 80 fps), ASW kicks in and util will drop by around 50%.

 

(I use fps/ ASW as examples for my HMD - Rift S, they'll most likely be different if you're using another).

a more detailed explanation

[Lanzfeld113]

Just some observations.

9900K @ 5.0

2080ti

16MB

 

It’s so strange but when I’m on the ground and I look certain directions at other airplanes that are on the ground my frame rate takes a hit. Very true with F-18.

Pretty much the same numbers for me with a 1080

Jumping in to report the same issues. I've been working really hard to find something manageable but so far, not much has worked. Even at everything low, it's still difficult to get above 40fps. (20/20).

you are correct about the asw kicking in. So I disabled ASW and now most of my 6 cores are under 50% and one is up to 80% max. For the graphics usage it's now up to 80% max.

So not sure if all this helps the developers

[speed-of-heat]

As dcs uses a maximum of three cores then slightly under 50% on a hexa core is the best you will get...

I was trying to help you, as it appears your system is not being used to best effect. Ideally, you want to have CPU AND GPU running close to but never quite reaching 100%. Whether you tweak your settings so that his happens at 40 / 80 fps is down to your personal preference of graphic quality vs frame rate. For 80 fps very low settings are necessary, unfortunately, and even then it's almost impossible.

 

With DCS it appears that just one of the cores does almost all of the work. This core can be the limiting factor (if the GPU isn't). In practice, what the other cores are doing doesn't really matter.

 

I would not recommend turning off ASW (unless you're testing). Constantly fluctuating frame rates are very uncomfortable.

 

What sort of frame rate were you getting along with what you describe?

 

I wouldn't know what helps the developers, but I would suggest that stating what sort of mission you were running, your DCS settings, screenshot(s) of your results, and your system specs could be useful.

 

 

BTW, it's just occurred to me that with 2.5.6 and a mission with lots of other (AI? static?) objects, you will get issues with DCS performing very poorly - if this is what you're experiencing, then, yes, there does seem to be a major issue with 2.5.6. I've stopped bothering with those sorts of missions on 2.5.6, as something is clearly broken. What I stated above appears to be valid as long as you are running a mission with very little going on. https://forums.eagle.ru/showpost.php?p=4237111&postcount=2

Sadly, no improvement on this poor situation. Very disappointing really.

Yes especially when VR performance improvement has been stated several times in the DCS roadmap update thread over the past two days.

[speed-of-heat]

yep no improvement here either...

 

@Bignewy/@NineLine/Kate on what machines were you seeing performance improvements in VR and what were their settings?
