VR Performance in DCS World

[SkateZilla]

Well, to be fair, that's a more or less accurate evaluation when it comes to AMD CPUs. They come nowhere near to the Intel Core family in gaming performance.

 

I have no Issues w/ My AMD CPUs at stock or overclocked specs.

(FX8350, FX8320, FX8150[ok the 8150 kinda has issues])

 

GPU's problems I have arent performance, but HDMI/DisplayPort Spec, since My GPU's Dont HAVE an HDMI PORT I tried using MiniDP->HDMI which dont work because the voltage range required by OR is above HDMI Spec, which is why alot of people are having issues with their 970s etc.

 

I had to resort to using a slightly lower spec GPU, and even then it does the job fine.

 

Polaris 10/11 and Zen are Out this Summer/Fall.

 

Zen 8 Core FX will have 2x the Performance of a Stock FX 8350 and run on 90w, and have single threaded performance just shy of skylake (less than 3%), and SMT so 16 Threads capable.

 

Im also looking at their 16 /32Core (32/64Thread) Server Chips for my server stack.

 

Polaris 10 Will be cheap and perform on the level of the 390x+, There's no info, but AMD's NDA is no where near lifted, Everyone will have to wait till the 1st/June and Later. (June29th)

 

Regardless,

This Winter I'll be going from FX8350 @ 5+GHz using 210w and 3x Lightings in XFire using about 980w

 

To Zen 8 Core 16T w/ nearly Double the Performance (170% over a FX9590 @5GHz/ 200% over qa FX8350), and a Polaris 10 Xfire or Single Vega 10 GPU

 

So More Performance on both CPU and GPUs while dropping from 1190w to 390-450w Load.

 

 

Side note, I dont run 3 Lightnings on a 850w PSU, only 1 Runs off the 850, the other 2 run off a separate 800w PSU using a PSU 8 16 Pin Split Cable to control both PSUs)

stupid question, why not just buy a DP compatible monitor? It's a better standard, just not as established in the marketplace.

My Monitors Run Fine on Display Ports, All 5 of Them..

 

it's the OR that doesnt

[_Acoustic_]

Can anyone help me out, Oculus support is basically nonexistent.

 

The OR Store says I have a firmware update for the sensor. I click on it and nothing happens, it acts like it DL's and then it quits the store, then reopens itself and the update is still there. I can't play any games and when I try DCS I only have 4 DoF, when I move side to side or in and out nothing happens.

 

$599 paperweight so far.

Reboot Your PC, Windows Will install Driver when windows loads up, you'll get a balloon saying installing and done.

 

I had that issue when 1.4 came out a week or so ago.

vicx, how do you disable track recordings?

Reddit user who got 1080 reports: "I can run DCS with high settings now. The camera is always wrong when I get in a plane, I use the view reset key RShift-Num5 to sort it out."

"I just found the framerate display in the game and no matter what settings you have it on the framerate fluctuates wildly, from 33-90, you can be looking forward at 90fps, look out of side window and it plummets to 33 or 45 - I couldn't discern a pattern. Both my CPU and GPU weren't breaking a sweat, running at about 35%, the framebuffer was maybe about 2GB.

I don't know if there are known issues with the engine for DCS, but it seems very odd to me."

That just shows that no matter how much muscle you throw at it, the engine is fundamentally incapable of rendering complex scenes at a high framerate. My bet is on DirectX.

[hansangb]

While I would agree, ripping out the engine while the car is running is hard to do. 2.0 is a good start, and I'm sure more is coming.

 

Also, Moore's law, and raw power never hurt anyone! :)

Thanks Skate, but still no luck. :noexpression:

My driver did the same thing, I ended up unplugging a few times and rebooting and eventually it updated.

[JiveMiguel]

I am looking around the forums, but not finding much- are the map and kneeboard going to be fixed soon? I am running 1.5.

[SkateZilla]

They are known Bugs.

Cool- thanks for the quick reply. Still enjoying plenty of seat time :)

Just got my Rift during the week and was majorly looking forward to trying DCS, DCS 2 completely hangs my PC every time I try and fly a second mission or make a change to the graphics settings, 1.5 is very stable but so far have only found two cockpits that get anywhere near 90 fps, the big Russian helicopter and the A10, the rest are pretty much unplayable, but choose an external camera even one showing the plane and the fps shoots up to 90, seems some of the cockpits are very badly optimised, hope it gets sorted because apart from the frame rates the experience is unbelievable, or should that be believable ? I'm running a 1070 and some sort of i5 with 16 gigs of memory.

It's just not quite there yet..

I am running a Titan XP (the new Titan with Pascal) and I can't maintain 90FPS with ALL settings set to low. The card doesn't blink hardly with the settings maxed out on Pcars, only if I take the MSAA up to 6x and ALL the settings on ultra will it slow it, at 4x and ultra it is smooth sailing.

 

Same with Prepar3D flight sim, I can virtually max it out.

 

Turning on the camera, or the mirrors, drops the FPS significantly in DCS and provides stutter. It's fun to fly around, but you can bring up the oculus rift toolkit performance hud and you will see it drops frames faster then m&m can spit out the words to rap god. :) Hopefully they will tune/optimize and look into Vulkan or Directx 12.

[iliad]

Old post, but, the FPS counter in games won't reflect the actual oculus FPS. You need to download the oculus toolkit and enable performance hud. It will be annoying, and in your way, but it is very accurate in the true FPS and dropped frames (which will be many in DCS)

[Rocky49]

careful with the oculus toolkit...there were some serious issues reported with version 1.7 don't know if problem was addressed by oculus

[Redlinebuzz]

My stuttering issues seem to have largely sorted themselves out, it could be that fact I'm using that Intel thing that uses a small SSD to store frequently used files so the PC can access them quickly and I've been playing nothing but DCS lately! Either way, the fps issue has faded far into the distance as I am totally lost if the whole experience, :)

Well I use the toolkit to moniter my FPS and lost frames... And I find the FPS in the toolkit and the ingame FPS counter to match.

Related tothis thread.

 

Getting bad judder in flying low in built-up areas on my Vive&R9 390 (but not in 2D). My comments (now in the proper thread):

 

Just checking in. Having the same problem with the UH1 Harbor Tour (and other areas). Looking out over the water is fine, but as soon as I look left toward the town it starts to judder. It got so bad at some points that I actually got black bars on the leading edge of my vision.

 

CPU usage is at 40-60% for most of it. I can't tell on the GPU usage, unfortunately, because my AMD card doesn't report utilization properly.

 

Tried the lowest settings and still unplayable. Deleting options.lua did nothing.

 

It's definitely a bummer, though, because 95% of the map is perfectly playable. I flew threw the UN Pilot career mission for a good hour without any trouble. But when I got to the LZ the chunking got so bad I botched the landing. Well, maybe I would have crashed anyway, but it certainly didn't help.

 

So now I'm left with the possibility of playing missions, with a creeping anxiety that it's going to end in disaster if I ever get near a problem area. The contrast between these areas and the rest of the map is nuts. I've been running 4x MSAA, and high textures and have had no problems. Hit one of these towns, and there isn't any setting that they work at.

 

What I'd like to know:

 

a) What's the time line to fix it? Or, if not a time-on-the-clock, what release is it expected to be fixed?

 

b) What's the min spec to not have this problem right at this moment? I've got one vote for a 980ti from this thread, but I'd like to know about the 1070.

 

Specs:

i5-4690

R9 390

16 GB RAM

DCS 1.5.4

 

ETA: Think I may have overstated it. It's visuals in Harbor Tour are particulaly bad when rising up over the bunker, but it settles down to blur with some minor judder with moderate head movement.

 

My hot fix solutions:

1) Don't look at the area.

2) If you do have to look at the area, don't move your head. It'll be just like playing the game in the old days without trackIR.

3) If you have to work in the vicinity of a low-FPS area, plan your activity to keep the problematic zone to the rear of the aircraft.

VR particularly in this type game is never going to be true without the use of the newer APIs imho if we're talking about gamer level hardware. Since I can't afford anything higher than that, that market doesn't exist for me so that is reflected in my current opinion.

What ingame settings do you use ??

Are you using the build in "VR Settings" optimization or just maxing the settings out? :pilotfly:

[Marklar]

I've just done FPS comparison between VR and nonVR mode using the same scenario - Ka50 free flight over Sukhumi. Very simple mission with almost non existent AI.

I was flying straight towards the town. At the start of the flight FPS were just over 200 (nonVR) and gradually dropped to about 150 when I was over the town. In VR mode I took the same flying path and FPS dropped from 90 (locked) to 50.

 

I am using graphics settings from this thread https://forums.eagle.ru/showthread.php?t=172537. It means most settings are low, off or minimum. My PC specs are: i7 6700K@4.5GHz, GTX 980ti OC, 16GB 2400Mhz RAM.

 

My conclusion is simple. This game is unplayable in VR mode. I doubt GTX 1080 would make a big difference. Whoever is saying that he has stable 90FPS is either lying or using NASA supercomputer.
