VR FPS (2.5.1.16543.355)

[imacken]

I’m curious also. I haven’t seen any setup that could consistently hit 90 FPS in VR and Persian Gulf. In Dubai, flying low in congested area with sunlight casting shadows I typically get below 45 (Vive Pro, overclocked 7700k as well as GTX 1080) even with compromised graphic settings. This would mean the rig has to be at least 100% more powerful than my current setup. Sure the 8700 and 1080ti are definitely more powerful than older gen but that huge leap of 100% in power does not quite make sense especially in gaming.

 

His system is almost the same as several others here - including me - and we are not seeing 90 fps.

It’s his settings we are interested in, but he’s gone quiet!

Sorry - gets busy around here.

I posted some pics with a specific setup requested by Hippo.

My settings yield a better rate. I'll post my settings, but my OC settings are in my signature.

 

FPS counter in the lower left is FRAPS. I used it for screenshots, each time I did its own counter dropped but the internal counter remained accurate.

 

Overclock on the card and CPU makes a big difference.

I'm also running a GTX1070 card, runs the physics for the 1080Ti, or so says the Nvidia software.

 

I used to have (2x) 1070 in SLI - which as was noted is not supported in DCS. Switched to 1080Ti but kept once 1070 to see what happened...

A. SLi/CrossFireX is not Supported by the Oculus API, nor the SteamVR API.

 

B. A 2nd GPU Offers more Hardware Resources for PhysX

 

Also B, Even though PhysX is not used by DCS, if it's Enabled and Set to your GPU, the GPU Driver Reserves Part of the GPU's Resources for Physics Calclulations, since he has 2 GPU's, none of his Primary GPU is Being Reserved.

 

Also B, This Option is enabled By Default in nVidia Drivers, Turning it to CPU or having a 2nd CUDA Capable GPU, Allows the Primary GPU to be 100% used for DCS.

 

C. DCS Does not run DX12, and never will, so there's no point in mentioning DX2's Mixed GPU Modes.

[Thudster]

Non-VR with the Asus G-Sync monitor in 165hz - 190 fps and on rare occasion more.

I built this rig for Prepar3d and really just shoved horsepower where I could. That it tunes well for DCS is a bonus.

[Thudster]

FYI - SkateZilla - I do love and appreciate your skins and work in DCS. The DCS Updater Utility is divine.

What settings and pixel density are you running in VR? I may look to give them a shot to see if I can get something similar in FPS, thanks sir :thumbup:

 

I'll get them together shortly.

Also a pic of the Ohio Air National Guard AV-8B I'm working on lol

Never will? What's the reason for that?

Hmm I didn't notice any framerate difference between PhysX set to Auto/GPU/CPU... I tested it in one of the Instant Action missions.

I never did when I used CPU for PhysX either.

In SLI mode I saw 20% utilization on my second 1070 card. Mostly PhysX and some management overhead I guess.

 

1080 Card alone was a big uptick in framerate from the 1070 cards.

Adding one 1070 card back into the box and framerates again climbed, where I started getting 90 fps in VR. 1070 Card is running 20-30% utilization. Other tweaks and overclocking give me stable 75-90 FPS in VR.

 

This is ASW OFF. PD 1.2 to 1.5

PD 1.6-1.8 if I want more clarity which trades for more frequent bounces in FPS.

 

Bottom line, it remains stutter free, no laggies, not getting seasick, can see all the words in the cockpit. Depending on the mission I'll sacrifice some framerate for added distance clarity if needed. But never am I getting low impactful framerate drag, no matter what the counter says as it hits 70-90 fps in PD 1.8.

DCS is going to Vulkan API

Does that mean there might be a chance of a Mac version to keep some of my friends happy? I believe Vulkan is being made available to macOS.

[imacken]

I'll post my settings, but my OC settings are in my signature.

 

Still no sign of these elusive settings!

Also, how do you overclock your 1080 ti? Any research into this suggests very little performance gain is achieved.

[Thudster]

This was helpful.

It's each of the steps from CPU and Mem XMP & overclocking, Card OC, second GPU, SSD's and M.2, killing un-needed services and apps. No one thing cranked it up to 90 fps.

Still no DCS settings from you. It would be interesting.

Yes, that video kind of demonstrates what I was talking about. He goes through all the maxing out to get around an extra 5 fps. Not really worth it, I would say.

[Thudster]

I hope this helps. I'm stable and done tuning until the tech or the game changes again, lol.

Doesn't sound like anyone here is new at this, so I'll skip most explanations and only reiterate what maybe tends to get skipped.

 

 

Thud's DCS/Prepar3d Setup

 

Oculus VR and Non-VR settings (noted where variable).

Setup is: Non-Steam VR and non-steam DCS

 

Gigabyte Z370 AORUS Gaming 5 Motherboard

i7-8700K CPU @ 5.0 GHz OC

32 GB DDR4 2800 XMP

(x2) M.2 PCIe NVME SSD

EVGA 1080 Ti Superclocked 11gb Driver 398.11 +50\+400

EVGA GTX1070 (PhysX)

Corsair Hydro Series H60 120mm Liquid CPU Cooler

Thermaltake Toughpower Grand RGB 750W Gold PS

 

Where are the gains?

Stability is a gain, network or CPU or GPU. Consistently available horsepower helps before you overclock anything.

 

Approx Gains for me from my start:

**Stabilization: 15+fps for consistent frames and performance, reducing variable rates,

ending on the higher numbers and staying there.

**Overclocking: 20+ fps with gains from both CPU, GPU, and memory tweaks. your mileage

may vary here. Best gains outside of hardware buys.

**Hardware: 30+ fps EVGA GTX1070 cards in SLI configuration to EVGA 1080Ti card paired

with a GTX1070 in non-SLI mode. Fast drives, M.2 & SSD.

**Network Tuning: Stabilized connectivity removed client-side lag and variability. Stutters

greatly reduced.

**DCS Settings:+20/-20 FPS based on adjustments.

Decide what is important for a given scenario or mission or flight and create configs

for each.

 

That choice for me is: Distance Clarity vs FPS Speed vs Close-Up Clarity in the

Cockpit.

Choose Two, One will suffer.

 

Tuning

Operating System engineered by removing bloatware, non-essential Microsoft Services

and Software.

This is for memory, CPU, threads, network utilization tuning.

Process Lasso for the remainder of the mess.

 

Over Clocking

CPU Overclocked to 50mhz. Water cooled, room air conditioning piped into the back

between the CPU and GPU.

With supplemental cooling I never get near any of the temp alerts for GPU, CPU,

Memory, or Power Supply.

"Supplemental Cooling" means I used a shop-vac hose & parts to send cold air

into the back of my PC. $25.

GPU Overclock to stable clock rate multipliers and memory multipliers. Only run in OC

while gaming.

Memory locked into XMP Mode.

EVGA Precision and test test test. Using Superposition Benchmark from unigine. Results

benchmark to 6300-6700.

I do not run the video cards at their highest capable overclock. I prefer longevity

and stability.

 

Process Lasso (purchased)

Bitsum Highest Performance Mode

DCS.exe and Oculus process have been given higher priority for CPU, Memory, and IO.

Creating a Game Profile with these reductions lowers other processes or stops a non-

essential process. Though minimal once you're in Bitsum mode, I'll take all I can get.

 

Network

Cable Modem delivering average 150mb down/40 up. Low latency to the POP.

Mesh Wi-Fi network so no shared bandwidth to the PC. I see no difference in Wi-Fi vs Hardwired in my config.

cFos Speed network tuning utility. Comes with the Gigabyte motherboard. Helped create

an optimized and stable packet environment.

 

Normally your packets and frames between your cable modem, wi-fi router, and PC

are not optimized and can cause lag if they are well out of whack and retransmit a

lot.

This takes care of that leveling. Or have a network engineer friend help you.

 

Tools:

Process Lasso: Windows processes and optimization

EVGA Precision: GPU Card tuning and OC

Superposition Benchmark: Change, test, repeat

Oculus Tray Tool: Control Oculus and ASW [if you don't turn off ASW you're stuck at 45 fps forever]

OvGME: Manage mods modules in DCS

DCS Updater Utility: Ya, gotta have it.

BIOS Tuning: For CPU and Memory OC.

Intel Extreme Tuning Utility: Hand to find where you what to be or create profiles if

you don't want the PC running hot all the time.

I have nearly the same settings. Except shadows low and global shadows default. I don't think I get anywhere near constant 70 fps unless I'm up really high with not much going on.

 

Also I'm using a Samsung Odyssey with PD of 1.5.

 

SSAA doesn't do anything for VR..some people mentioned it's mainly for monitor use. I haven't tried to turn it on but those who have have said it stretches things out, scales them weird?

 

Despite not getting the fps you get, I get no lag or stutters so that's really all that matters at least to me.

What I've heard from folks that might be different is:

* Thinning out windows processes

* Ensuring memory is in XMP mode

* Motherboards matter. This one is known for high throughput internally.

* Overclocking matters.

 

*SSAA: That's a non-VR setting for me I use with Delan Engineering Tracker for setup or learning an aircraft.

I'll try using shadows that you have going on and see what happens. I've had my memory over clocked to xmp profile and the 8700k to 5.0ghz but I don't think I saw much of a difference in fps gain. I have the Asus strix z370 e gaming board. So I just took the OC off and kept it stock except the memory. I agree with windows processes being shut down that you don't use. Probably uninstalling unused mobo apps too that always start up in the background when you boot up.

 

What do you use to record fps while in VR? I dunno if steam VR has anything to do that. I also think occulus software runs better than wmr but I haven't used my rift since I got the odyssey.

My memory is XMP to 3000MHz, and I have the ASUS Z730 ROG STRIX, 8700 i7 o/c to 4.8GHz etc. and I get nothing like what your fps is.

In my experience, overclocking makes little difference, and certainly nothing like the amount your fps is showing.

Re windows processes, I am showing only 1% CPU atm, and 3% GPU running this browser!

I am going to try your settings as mine are set higher, but I really am struggling to see how you can get a solid 70-90 fps.

I use the Oculus overlay or Oculus Tray App for in-game FPS. I use FRAPS as well and I get screenshots using FRAPS. But their FPS counter lags when I take a screenshot with their software.

** I should probably note that this is NON-STEAM...

DCS has a built in fps measurement. Press Ctrl-break to bring it up.

Interesting, didn't know if that worked while in VR mode. I'll try using it tonight to see what I get.

[Thudster]

When I'm in VR ( RIFT ) my desktop screen shows only a quarter of the screen in VR mode. How do I extend the laptop desktop screen to full screen mode for recording my VR flying ?

 

thanks

 

 

You search YouTube of course...

Yep, it’s fine in VR.
