New i9-13900K & RTX 4090 PC and suffering stuttering on all settings so far?

[minimi66]

Every single non-essential background process also disabled with zero effect on stuttering.

The Quest Pro's Resolution is 1800 x 1920 per eye. When I look it up is this wrong or is the setting in the program? My Hp G2 will show as 4320 x 2160 pixel combined or 2160 x 2160 per eye resolution. I would think If a Quest Pro is 1800 x 1920 your pixel combined would be 3600x1920. In the Quest Program it says it set at 5408 x 2736. That is way to high set it to 3600 x 1920 or 1800 x 1920 per eye. Forgive me if I am getting this wrong I do not have any Quest Headsets.

Settings are fine (Quest Pro user here). The higher the resolution the sharper the image gets (supersampling). I am currently running a combined 6752 x 3472 resolution with my RTX4090 - no problem in DCS.

Sorry for the OP having these issues with that beefy hardware. I suspect the i9 having problems with the P- and E-cores with DCS (read some DCS thread having this issue with DCS MT). Maybe Process Lasso can help by setting the correct core affinity. But I am no expert with Intel-CPU's - just a guess.

Thank You for that info. I never have used a Quest Pro Good To know. If I may ask In addition to this Topic. How do you set up your OpenXR Toolkit Companion? do you run Turbo Mode ON or OFF? He still could use help from a RTX4090 User. Thanks Again

Nothing special in my OpenXR-Toolkit.

I am running DCS Open Beta with OpenXR and Multithreading (shortcut: "C:\GAMES\DCS World\bin-mt\DCS.exe" --force_enable_VR --force_OpenXR).

Turbo-Mode is on and CAS (sharpening) is on. Some tweaks for color saturation and that is it.

DCS with Multithreading really did come enjoyable in VR for me when enabling OpenXR Turbo-Mode and also activating HAGS (Hardware-accelerated GPU scheduling with Windows 11).

OP is on Win10 - I think that option is not available there.

As far as I can tell, no clue what else the problem could be.

Thanks for all the above guys, i really appreciate your contributions to trying to fix this.

I did try and upgrade to Windows 11 a couple of nights ago but when i ran Windows Update to upgrade it downloaded the Windows 11 files but then said it was unable to install them at this time??  So that option also seems closed for now as well.

I have tried to get my head around Process Lasso but i really don't know what i'm doing with it.  I was able to set whichever DCS executable i was trying as High Priority no problem but i don't really understand the Affinity setting and what i would need to set?

The bizarre thing is that when my new PC arrived about 2 weeks ago and i first installed DCS and ran it with the Quest Pro it ran like a dream.  I have no idea what changed and what  started this horrendous stuttering.  Maybe another piece of software i installed? I may have to just restore my PC with the recovery media that came with it and start from there?

Now for the rant!

As i said in my original post i bought this PC first and foremost to play DCS in VR with the best settings/experience possible. I am frankly shocked and disappointed that even with my new hardware and current DCS MT technology (albeit nascent) that this is not currently possible.  The PC was pre-built by Scan Computers, one of the largest and most popular Gaming PC companies in the UK.  Total outlay for PC and Quest Pro and a new Asus ROG 43 inch gaming monitor was over £5000.  Every other PC game i have FPS, RTS etc runs perfect on max settings without any tweaking whatsoever.  Not so with even the latest Stable version of DCS World? 

Does this say something about my hardware or about DCS World as a software product.  I've been flight-simming on PC since 1992 (Microprose F-15E Strike Eagle 2) and yeah of course i have had to do a TON of tweaking and fiddling in all those years but i guess you just hope that maybe one day you'll get a Flight-sim title you enjoy that doesn't require a Degree in Computer Science to configure and run to a satisfactory degree.

This thread should serve as a warning to all DCS fans who are considering expensive hardware upgrades?  Think carefully before you click on that buy now button!  Not saying you shouldn't  buy DCS or try it but maybe not have such high hopes for improved performance with newer hardware. 

I'm sure the DCS Defence League will now come down on my ass like Shock and Awe but to be honest bring it on!  I'm pissed off!

Again though, i'm truly humbled and grateful to all the above who have tried to help me fix this issue and hopefully will continue to do so.  Thanks guys, you're Legends!  Peace!

HAGS is currently on and working from what i can tell mate.  Thanks for those tips though will try later after work.

I totally agree with you on this one. It has been a hit or miss with upgrading hardware for DCS and could lead to many frustrations, especially with patches in OpenBeta that could break the entire performance with just one patch for half the people.

Well, it is what it is for now. The engine is outdated and not well optimized - especially with VR, I hope ED tries it's best to keep up.

I also think it is a shame that there is no dedicated and optimized VR-branch for DCS. Especially alot more fine-tuning graphics-options would be neccessary for alot of people with VR and this gets ignored year by year from ED. In the long run ED just have to wait until the hardware components gets better and better and hopefully compensate the lack of optimization and laziness in coding it seems. This has been their strategy - no competition on the mil-sim-market, no need to rush.

And don't get me started with the Early Access Module Policy. The F/A-18 launched May 2018 in Early Access - it is now 5 years and this thing is still labeled Early Access and not fully feature complete to this date. Pathetic.

@minimi66, If you have the time and patience, backup settings, then erase everything and re-install windows from scratch using FR33TY's methodology:

I did it and was very happy with the improved performance and stability.  Either windows 10 or 11... 

[dburne]

Sounds like time for a clean sweep of everything and fresh install of Windows. IMHO.

[Hiob]

I haven't read the whole thread - but before wiping Windows (which isn't usually neccessary these days) I would try and check the following (if you haven't already):

- Check the export scripts for winwing crap and disable it.

- use a different USB-Port (different controller if possible) for your VR-Headset (use USB 2.0 instead USB 3 if supported)

- update your USB-drivers in windows (and/or chipset drivers)

 

Good Luck!

OMFG!!!

You absolute beauty you!!!  It not only fixed it but its purring like a kitten!  ZERO stuttering at settings below in F/A-18C in Caucasus Weapon Practice Quickstart mission, 600 KTS at treetop level over all terrain types and all altitudes.

Followed all steps other than the over-clocking ones which hopefully i won't need now and it worked first time on clean Windows 11 (as opposed to W10 previously) with fresh install of Oculus Client and factory reset of Quest Pro headset.  No ODT/OTT or OpenXR Toolkit.

Started with default Oculus client Refresh Rate and Rendering Resolution and moderate to high in-game settings.  FPS in-game was absolutely rock solid at 72 Hz, the most flat and constant frame rate i've ever seen in the games Frame Counter.  Non-VR on MT exec was 100-120 FPS with everything maxed in-game.

WipeUout i owe you (and FR33THY) ten beers each!!  Thanks so much for the tip and link.  It took me about 2-3 hours to go through the whole video/process.

Literally DCS OB, Oculus and my web browser are the only software on the system right now so i will have to closely monitor what happens when more apps are added.  

Next step is to try 90 Hz Refresh and creep the Rendering Res up with the same in-game settings and see what happens.  Hopefully i'll be able to gradually crank up in-game settings along the way as well?

Happy Camper here!!!

Congratulations!

Can you, by any chance, pinpoint the culprit? Could be helpful for others in the future...

[WipeUout]

Glad it worked mate, happy flying!

[DishDoggie]

Congratulations to both of you Glad your system is ROCKING and To the Hero that Solved this for you. AWESOME JOB.

That might be tough i think given the rather drastic and  all-encompassing nature of my actions.  Trust me though i am watching like a hawk now for anything that i do/change or install that seems to negatively affect performance.

I just tried free-flight mission in Marianas map and it was a lot worse than Caucasus but not really surprised by that as i understand that map is very demanding and dare i say it not terribly well optimised yet?  Its ok at medium altitude but lots of stuttering at low level.  I never play it tbh so its not an issue for me at the moment.

I will keep this thread going an add updates as i crank up the various settings etc.

[minimi66]

90 Hz Oculus refresh rate no negative effects.

I was just curious. I watched the Video above and have a bit mixed feeling about it. It's not bad or wrong, but a bit convoluted. Some of the stuff is more for basic OCD-maintenance (which isn't bad inherently) and has no impact on performance whatsoever (deleting temp files e.g.). I can imagine it is pretty overwhelming for less advanced windows-users.

[minimi66]

Max Oculus Rendering Resolution and 90 Hz Refresh Rate.  These were on MT executable, results on ST were ok but not quite as good.  Pretty close though.

Yeah definitely agree and not at all really specific to flight sims really.  He makes no mention of sims of any sort.  For all i know i simply needed to do a fresh install and switch to Windows 11 and that made the difference?

Now all i have to do is not f**k it up again!!

Who knows...

doesn't matter - Most important thing is that you can enjoy it now.

Yeah its playable with the kind of settings i originally expected!!!

[Tea-Pig]

Oh how I wish I'd seen this thread a few months ago. I've just been reading it thinking it's exactly my experience: expensive new system, works great with everything except DCS which is a stutterfest. And for me the solution was the same: wipe DCS completely and reinstall from scratch (I didn't wipe Windows). So I'm leaving this comment to bump up the thread and hope it gets noticed by some other stutter sufferers.

[Thundersmoke]

For those with high-end Intel CPUs experiencing this issue, the solution isn't nearly so drastic:

Getting DCS onto the right CPU cores and freeing up the others for the less demanding applications will sort you out with respect to stutters on high-end systems.

[minimi66]

Yes, i did this a few weeks back after seeing Spud's video.  Definitely helped quite a bit despite my system still running really, really well since the complete re-install etc. described in this thread.

Everything is still running really well, i now only use 72 Hz refresh rate in Meta Client as it gives amazingly consistent frame rates with graphics settings i am MORE than happy with in VR.
