Terrible VR stuttering in 1.5 with 1080 Ti and Oculus Rift

[hansangb]

Ah, yes, I'm afraid I added confusion because in my mind I mean 2.0.5. Either way, your performance is a little better than mine. But that little means a lot -- 45FPS is fine, 22/23 is not. I have an i7-4790K that I just OC'd to 4.7 Mhz, with 16 GB DDR3 1800 on a Z97a1 mobo. GPU is the same: 1080 Ti .

 

 

You know, I just read the reddit thread where one guys saw noticeable improvement with faster memory. So I added the speed on my .sig (helps the developers). And the speed I got was with the older Maxwell based Titan X. Last night, I upgraded to 1080Ti Hybrid (no overclocking yet) and saw nothing but 45 and 90FPS.

 

 

Thanks for the utility link.

I did run it for a week with framerates between 45-90 FPS (With Viggen & others in 1.5) All settings at max almost.

 

Now a got some windows update / new Nvidea drivers and the high framerates are gone, both 1.5 & 2 stutter like hell and the game crashes into a black screen.

 

I noticed in DCS 2 that when the picture was only visable in the Oculus and not on the monitor my framerates went up again to 90 Fps.

Butt when I activated the screen with my mouse on the monitor I had stutters again.

 

Oculus set to run "untrusted apps" YES

M2 SSD YES

GTX G 1080

32 GB RAM

6700K at 4.2

 

Best regard Grippen7

 

 

It may help to reinstall or at least do a repair (SkateZilla's utility has the option or you can do it from command line - see this post for more info)

 

Out of curiosity, what is your RAM speed? And is it DDR3 or DDR4?

With various tweaks and and turning off mirrors (big difference) I can now get pretty smooth performance in 1.5 with ASW at 45fps.

 

I'm flying the F-5 and the MiG-21 a lot. It's silky smooth in the F-5 now, but the MiG-21 continues to stutter for some reason.

 

Even turning down graphics and PD won't get rid of it.

Make sure you use the mission editor to optimize your missions and get the best experience as well. Clouds off!

Honestly I'm having incredible results with this https://forums.eagle.ru/showthread.php?t=187520 I can post my ingame settings later, but my stream quality is amazing now, and MP performance is really good, able to stream 1080p60fps without issue while on BlueFlag and other various servers. Hand full of places on the map where I drop to 20 fps or so, but its only heavily populated areas.

stutters and nothing but stutters each time i turn my head around...

 

i have enough pc power to fly to the moon but everything on low and still stutter. fps has nothing to do with it..i have 45-60 in vr but it stutters each time i turn my head to an unplayable level.

 

i have an evga ftw3 gtx1080ti...the stutters are only in vr

Are you sure you don't have v-sync ticked in settings? This causes stuttering

[sleepara]

i have tried everything ... starting from bios up i was able to reduce it but there is still an annoying micro freeze or stutter every second when i look aside. and above all that there is an underlying microjitter and the game is not fluent and smooth. i have the pimax 4k vr hmd...17ms frametime and up..resolution tweaking didnt make any difference. no stuff in the background just a clean install of win 10, dcs world and pimax drivers.

set your preload radius to the maximum

[sleepara]

check...no joy

 

none of the graphic options seems to completely eliminate the stutter. i know why it happens but i dont know whats the main issue that generates the extremely high frametimings. im running 60hz hmd vr set with optimal ~16 miliseconds frametime. it stutters when i skip to 17 , 18 and all the way up to 33mil seconds timings.

[Red Hayek]

Got all the processor power management turned off?

 

And "prefer maximum performance" checked in the graphics board control panel?

[sleepara]

yeap...there is an entire list of tweaks i have tried..bios is super optimized and so does win 10. all drivers up to date..i hope its not my 1080ti causing trouble...heard guys complaining about stuttering with this card and then switching to 980 and stutters gone.

[Red Hayek]

Completely removed the nvidia drivers - there's a utility for this but I can't remember the name - and installed an earlier version?

[hansangb]

any mission in 1.5 stutters? It's a long thread, which aircraft and which instant mission?

[simo1000rr]

Also do you by any chance upgraded to Win 10 gaming ? this i heard has stuttering issues in DCS

[sleepara]

no i haven't upgraded to the creators update..both 1.5.5 and 1.5.7 stutter..even 2 alpha stutters.

a-10c is the aircraft and stutters occur in any mission...

regarding the DDU software and nvidia drivers - yes i have done that and it made no difference

[Baggy MacDouche]

In the same boat. I've put DCS on the back-burner for awhile now. Every time I try and revisit it, nothing I do seems to make a difference. Playing around with every combination of settings both in-game and SteamVR.

 

I'm using a Vive on i7-6700k@4.5Ghz, 1080 Strix, 32GB Ram, SSD install, W10-Creators w/Gaming Mode OFF.

 

Get major stuttering on head rotation, and intermittent stuttering/pauses(flashes Vive loading screen briefly). Trying IA or custom missions with low assets in A-10C.

 

I know awhile back there was a time where it ran great, so something's up, and not sure what combination of things have made it worse.

 

Same for 2.0 and Normandy/P51 is absolutely a slideshow.

 

This is unique to DCS as everything else I put through their paces with as much SS as possible, runs fine. Heck, I run ED at 3.8 SS(in-game .65SS/HMDQ@1.25) and very high gfx settings with no problems.

[sleepara]

what frustrates me the most is the fact that it runs great on some systems and displays slides as you mentioned on the others. my screen renders a whole different story which runs smooth without the slightest of stutters or freezes , but my vr hmd is simply unplayable..

yesterday i have found a solution and i get no stutters what so ever...i just dont play dcs hehe

I know how you feel! I too would sooo wish DCS ran smoothly in VR. In the meantime I now play warthunder, which is SUPER unbelievably smooth in VR even in full sim mode. I suggest you do the same to get your flying combat fix ....for now until ED get moving on giving VR more love

[PreussLee]

Hm...are you guys using game mode in windows 10 maybe? Because i dont have any major stutters in vr even on crowded servers...

Or you are just using too high settings...there a tons of threads in the forum that discuss which settings people use flyin in vr but some tips i can give are: In 2.1 dont use deferred shading with msaa or af, i turned it off and play with 4x msaa because i cant stand the shimmering without msaa. Dont use to high pixel density, 1.6 works fine for me...shadows, traffic and visibility also have big impact on fps. And still as a vr user you are damned to just fly on sunny weather without clouds. So the vr defintly needs some optimizing from ed, but tellin its not playable is just wrong if you fiddle with the settings around a bit

[hannibal]

im sad to hear all the performance issues.

i just ebay'ed one of my 1080s to bring in some $$$ to get a 1080Ti.

 

ED HELP US VR users!!!!! (praying hands emoji)

[Redlinebuzz]

I have a sneaky suspicion that the Pixel Density in 2.1 is not working, I see no difference between 1, 1.5 and 2 I only noticed it because I couldn't read the gazelle gushes anymore, setting it to 1.5 in Oculus Debug works fine though. As for stutter, if I have any shadows at all enabled and look of the right window I get horrible stutter, so I don't look out the side window much !

Every little bit helps! And agreed on hoping DCS gets more optimized for VR. It really is the future of flight sim'ing

[lazduc]

What version are you guys using? If you are using the released version then this is really not good news.....I guess even the release version is a WIP...go figure.

[oho]

It must be something different. I can Play Instant Action A-10C Scenarios without serious stutters (it is definitily playable) with PD set to 1,8, shadows on, AntiAliasing 4, which gives a good Picture and readable MFDs (at least with zooming in) with Oculus Rift and a Geforce 1060 (6 Gig-Ram) and an AMD 8300 CPU.

More Problems and stutters are in the stock campaign but I can Play it too.

F15C makes no Problem at all because you fly very high, also through clouds.

[BeastyBaiter]

I've largely stopped attempting to play DCS 1.5 due to the horrible performance in VR with a Ryzen 5 1600x and GTX 1080 TI (it's ok on monitor though far below what it should be). The problem is DCS is single threaded and DCS 1.5 doesn't use any sort of clip mapping, and so everything is rendered, even stuff behind a mountain. Additionally, nearly all graphics load is placed on the CPU rather than GPU. There are areas where I can get 90 fps on max detail with a decent sized battle going, and others where I get 22 fps in a completely empty mission at minimal detail settings. And there is no real pattern as to where since it isn't just stuff that's actually in view that slows it down. With very careful mission creation to avoid the low performance areas, it is playable but the hassle of doing so kills it for me.

 

DCS 2.x runs much smoother and so I do play that a bit. But even it is very poorly implemented since it's still single threaded. I've mostly been playing BoS and some shooters due to this. Matt did suggest in a recent video interview that they were working on multi-threading the game, but that hasn't happened yet obviously. Hopefully we don't have to wait too long. I really, really want to play this at 90 fps all the time in epic battles, my 1080 TI will support it and I have the CPU for it too. But the game engine has to actually make use of the hardware rather than trying to run as though we're all still using Pentium 4's and Voodoo 3 graphics cards.
