Cannot get decent FPS in VR (1080ti)

[indep]

Hey guys

 

So i recently started playing with a Vive and while i can tell its going to be amazing (one day) i am so beyond frustrated im ready to go back to my TIR.

 

My computer is as follows:

 

i7 4770k

16 gigs ram

1080ti

512g SSD

 

Temps are fine.

 

 

In the A10c which is what i play mostly, i cant get above about 35 FPS (using nvidia FPS counter) in DCS World Single Player.

 

I can safely say that i have watched 10 videos and read a dozen or more posts about settings and i have tried just about everything. I have turned down the resolution in steam VR. I have turned down the pixel density. I have launched the game without steam VR being on (let the game turn the goggles on) I have tried low/Med/High settings. MSAA on and off.... Just about everything in several combinations. Even with the resolution in steam VR all the way down i didnt get above 35 FPS and it looked awful.

 

Does anyone have any suggestions? Could it be my CPU throttling stuff? (its quite old now but runs literally everything else 100% fine on max settings)

 

Anyway i am on my last leg here before throwing in the towel and going back to TIR. The immersion isnt as good but at least it looks amazing and i can read my gauges and not lag all over the place.

Are you overclocking? If not, I'd suggest it.

[Mars Exulte]

Most other stuff is not CPU intensive, DCS is, that said I don't know where a 4770k falls in comparison to more recent stuff, but I get better FPS than that running triple monitors on max settings, so it's not the GPU, at least.

[David OC]

We need to know what your card is doing? I can easily hold 45 fps and up to 90 when not need city's etc. I hit VR preset turn the textures to high, view to high and have the PD set at 1.6. You also have to be careful to not play large mission, otherwise these settings will need to be turned down a notch here and there.

 

Make sure in Afterburner your GPU is running at 100%

 

It should not look like this pic, if it does your CPU is not feeding the GPU quick enough, it should stay 100% all the time.

You didn't specify your settings properly pixel density etc. But I can tell you from my own experience I used to have the i7 4770 and it was bad enough before defered shading became mandatory. The reason I didnt just buy a 1080Ti was for this very reason, as a good CPU and GPU are supposed to go hand in hand. But I would have thought without MSSA it should be playable. But running everything else fine means nothing, DCS is the most demanding game/sim I own nothing else even comes close.

 

 

 

It also depends what missions you are flying, you cant really play DCS VR as you would in 2D, or have the same expectations. You need to use the mission editor and make adjustments, which ussually means things like turning clouds off, and limiting the number of assets or other things that might tank performance.

 

 

How does the other sim perform?

Also be sure that in your Nvidia control panel that your power management mode is set to "Prefer Max Performance" to make sure you are using your Ti to its fullest potential.

OK I get you are frustrated.

I have about the same you do - Ti Vive hot computer setup.

 

 

First realize the 35 fps is for each eye. That is combined 70 fps. Not bad.

The 90 fps min they set is for the average of all persons.

 

 

There is a new flight sim, right out of the box, I can get 235 fps, but the sim

doesn't really do much - yet.

 

 

It's not "how fast can I make my fps", you should instead ask (yourself), "what is the min acceptable fps to prevent me from motion sickness".

 

 

I have been just fine at 20 fps (each eye).

Most of the time 30 - 35 fps is max I get.

 

 

They will be coming out with the 2080Ti soon. That should boost video

 

performance by about 40% - but, that will not guarantee you will get above 35 fps in DCS. Al lot of it has to do with how the game is written.

 

 

X-Plane 11 will bring the most powerful video card(s) to its knees, if you crank up the graphics.

 

 

1. Keep the graphics down.

2. Use 150% supersampling in the Steam VR settings box.

3. Use 1.0 in the VR setting in DCS.

 

 

That gets me about 35 fps without making it a slide show event.

 

 

Hope this helps.

I do agree, the future is bright for VR.

Meantime, I'm willing to put up with a few frustrations in order to get the depth perception and ability to look around "IN" your environment.

 

 

With a flat TV screen and TIR, you are 2 dimensional at best.

 

 

This is my mileage.

As always, yours may vary.

[DayGlow]

Also, make sure you don't have supersampling/pixel density on both in Steam VR and in-game, choose which one you want to use, as they will compound each other.

[Doum76]

I know how you feel man, but even with my old i7-2600k not-overclocked, GTX 1070sc 8gb and my small 16gb ram no way will i ever, ever go back to my TIR, i'll ratehr have my 35-45 FPS as this with my Oculus than going back with TIR to have better FPS.

 

 

 

Wish you the best my friend

[YugoThunder]

If you have some extra money to spend, you could wait for the new RTX 2080/2080ti GPU's coming this fall. Rumors say that they will have a huge performance plus for VR-Users.

 

Your CPU is still good, but you could try overlocking it for some extra performance.

[The_Nephilim]

AS said previously Overclock the CPU if you have proper cooling fan and heatsink..what will help also is your setting's ingame and in nVidia control panel can you post those up in a picture..

 

 

Also besides Overclocking the CPU, Are you using the XMP PRofile for your memory if it is available??

Thats good advice, i will monitor the GPU to make sure its running 100%

How does the other sim perform?

 

Well i bought the TI because i am upgrading the rest of my CPU when the new intel line comes out this fall. Considering my computer runs every other game i play (including DCS just not in VR) on max settings i didnt expect to have such a massive bottleneck at the CPU.

 

I knew VR was more taxing but i just didnt think i would go from over 200 FPS on max settings to less than 40 in VR with stuff turned down. And considering people claim to get 90, even though my CPU is slower i still expect to get at least 60-70...

 

Also be sure that in your Nvidia control panel that your power management mode is set to "Prefer Max Performance" to make sure you are using your Ti to its fullest potential.

 

 

 

It was set to use global settings, i changed it to MAX for DCS, will report back on this. Thanks!

 

 

Thanks everyone for your advice i will keep chugging away at this.

 

One more question, when in VR you can see what the person in the goggles sees on the computer screen, that is where my FPS is being displayed. Someone said that this is per eye and you have to double it to get your real FPS? Is that true?

[indep]

So i went ahead and did a mild overclock on my GPU. That gave me about 10 FPS. I sat at about 45 most of the time.

 

In afterburner i did get to 99% GPU usage but not constant, that was just the peak. My CPU however never got above 80% usage so i am not sure that it is my CPU throttling me.

 

The GPU stayed around 80% most of the time.

 

Again temps were perfectly fine too.

 

I am just at a loss at this point. PD is set at 1 and the supersampling in steam vr is set at 100%. Again, its playable now and even enjoyable but still not where i would like it but maybe when i upgrade the CPU in the fall i will see improvement.

 

Thanks again for everyone's help

[Hippo]

My CPU however never got above 80% usage

 

 

Is that the "average" reading? You should look at each core individually, and there will be one which is being most heavily used. If that's at 100% then, yes, your CPU is the bottleneck.

 

 

I would offer more suggestions based on my own experience, but I have a Rift and am not using the Steam version of DCS.

None of the cores got near 100%. The average was around 50 or so.

[Hippo]

None of the cores got near 100%. The average was around 50 or so.

 

 

So If I understand correctly, your most utilised cpu core and the gpu usually both run at around 80%? On my system I would put that down to ASW kicking in (i.e. being unable to sustain 90 fps), and would expect to see 45 fps (dependent on settings of course). Unfortunately, I have no idea how the equivalent Vive mechanisms function.

 

 

Are you unable to get 90 fps no matter how far you lower your settings?

 

 

Have you tried using the in-game frame rate counter? Does that agree with the one you're using?

 

 

IIRC, in Steam VR, there are general PD settings as well as game-specific ones, and they multiply with each other (have you checked this)?

 

 

Some further suggestions: Read all of the following post

 

 

https://forums.eagle.ru/showthread.php?t=215853

 

 

Towards the end I posted some settings and resultant frame rates. I'm not suggesting that you use them, but maybe try them as a comparison, and see if you get similar frame rates to me. Please note that I am trying to argue a different issue in that post, so you'll have to give me some leeway.

 

 

 

There are also many other threads relating to VR performance in that forum and it's worth going through them.

 

 

There is also a mod out there that can get you more frames (Kegetsy).

 

 

 

If you mostly fly the A-10C you could consider using v.2.5.0, as that still had the option to disable deferred shading, which could get you some more frames.
