stuttering, frame drop, micro stutter, micro freeze

[jarekzegarek]

This is more or less a shortcoming of the WiFi standard you are using.

 

Never had any stuttering/instant frame drops in any of my games. It happens only in DCS. This issue starts a few months ago after one of the DCS world updates. Have over 15 devices connected to my network. But it seems that only the printer causing a micro stutter in DCS. I always kept my wifi printer on before. This is why I do not think there is anything wrong with my "wifi standard". But thanks for Your reply.

Dear community,

 

 

As advised I disconnect my lan cable et desactivate internet device but stutter are still present in mission when RWR sound is emmitted???

 

 

May be it is due to my poor CPU which act as a bottleneck when two much A/C and ground vehicles are concentrated on the map.

 

 

 

 

I noticed on the su25t mission "long day" that I have graphics stuttering each time the rwr sound is emitting especially when I approach target zone. I have checked everything:

latency ok

last drivers ok

optimisation according the main post of this section

fox and metashader2 deleted

 

when I check in game fps, I have very good values between 70 and 110 fps.

but when the rwr sound is emitting, you can see a short 25 fps drop of few miliseconds which cause this very annoying graphic stuttering.

my config i7950 @ 4ghz 1080ti 12 to ram ddr3 ssd evo 850 500go.

Black Screen

 

Screen goes completely black for about 3 seconds as the game continues to run. All I can do is cross my fingers that the aircraft will not crash. This is not a blackout type moment due to high G. This happens during normal flight, sometimes a minute after takeoff, and sometimes after 20 minutes. Then all of a sudden the game comes back on. I run the game in VR with the Oculus Rift.

 

It is identical to the black screen during a catapult launch before they fixed that issue, but maybe a few seconds longer.

that's caused by bad ethernet drviers causing high DPC latency....

 

 

you should either upgrade your lan drivers + bios + chipset if necessary.

The autoexec.cfg file dont work here. I think its because my windows is not in english so the path to autoexec.cfg folder has other name in the middle.

I hit CNTL numpad 1 to disable the in game ASW and that seems to stop the blurred double image in VR.

[Shadoware]

I moved only the map folder to my ssd(with symbolic link) and the micro freeze has stopped.

 

 

Obviously the problem is related to data streams from hdd.

nobody is using HDD for gaming anymore in a modern PC

I have about 300 games on Steam. Many non installed and dozens installed but until this date I only needed to put 2 games on sdd for performance issues.

A well programed software doesnt need a sdd.

I don't get this at all...one day its fine with a certain patch, next update it goes to the dogs...back and forth. Stutter feast one day ,fixed with next patch ,then stutter a following patch. Very inconsistent performance wise. This patch flying the F-14 is painful(yet flying the ka-50 or mig-29 is fine) I don't know what to make of it.

[boedha68]

F-14 is a worst frame killer in VR! :cry:

 

EDIT: fiddle setting was in my case ASW setting too 45 fps. All is fine now. (FIXED)

also in 2d

The fps takes a big hit with mirrors on. On the flip side.. I can load up the carrier deck with Tomcats and not even dip below 60 fps at all. Add more than a few Hornets and it's a different story.

Just wanted to update everyone, after years of having this issue, I can say its 100% fixed! here was my solution.

 

Before chucking up 1500-2000 bucks for a new PC I figured I'm still within the top 10-20% pc's playing games with my system. I figured my old 128gb ssd drive needed to be faster, I went and finally got an M.2 drive and stuck it in. I then did a completely new install of Windows 10. I took my old dcs folder and copied to the new m.2 same drive as my windows install this time. I then copied the user/saved games/dcs folder to the same location. Did a repair/cleanup and it loaded some stuff but for the most part all good

 

loaded the game and.... micro stutters :(

 

not as bad, much better but they were still there. I was going to live with it, but took a quick look at my saved games/user name folder and saw it was at almost 20gb, mostly the multiplayer trackfiles that was using that much storage.

 

I decided to just delete that whole folder and do another repair and start fresh. Sure the @#$#@ enough, its PERRRFECT!! Have not played DCS in years this smooth, even if I drop into the 40-50fps range I don't even notice it. Also I noticed my GPU is now running at 95-100% usage, before it was closer to 50-70%

 

not sure what exactly the problem is, but for anyone with this issue please try deleting that folder (c: <username> saved games/DCS delete the DCS folder and then do a repair via command prompt)

 

I have read dozens of posts with this issue and not one that I have come across had this advice.

 

Thanks!

All you needed to do was delete the fxo and metashaders and the tracks/multiplayer folders from the Saved Games DCS directory, not the entire thing.

[valrond]

Well, I can't play anymore. I've spent the whole day trying to solve this to no avail. I have two installations, one in a SDD, another in a regular HDD. I have 16 GB of RAN, Ryzen 1700x, GTX 1080Ti. Just two days ago was working perfectly, then in a mission with the C101, it started to stutter at the end of it, now it just won't let me play more than 4-5 seconds, stutter/freeze, then back, on and on.

 

I have tried the usual suspect, deleted fxo and the shaders folders, went back to stable, took out all background processes, changed full screen mark on/off, even upped the refresh to the 100 hz my screen is capable of, repaired the installation. Nothing will work. It is just unusable.

[Strikeeagle345]

Have you tried other games, do they do the same thing? IF you dont have anything else to try, have you run a stress test / benchmark tool?

Yep, all my other games play perfectly. I played War Thunder at max detail at it stayed stuck at 100 fps. It's not a problem of my computer, no game ever does that freezing for 1-2 seconds then back.

 

 

 

This is on DCS.

[valrond]

Well, I finally found the problem. It turns out I had too many USB devices connected, so I turned off a few of them, external HDDs, Xbox receiver, and it is now working fine again.

i use it and have the same system as yours with gtx 1070oc no problem at all

Overloaded PCH

 

USB can be tricky

All in all USB is just some sh!p that's still in early access quarter a century after it's introduction. It's the only cause left for BSODs (especially in combination with S3 states) in more than a decade for reasons after all.

 

Having noticed better performance especially in DCS myself with everything unplugged and just trying to watch broken tracks

 

But it's hard to fly without HOTAS, TIR, FFB stick, pedals, keyboard, mouse and some extra sliders attached...

 

And I've seen utterly heavy interferences with TIR and FFB resulting in very bad fps drops when slewing the view in other sims. Thank Celie this issue is unknown to DCS

Gotten sudden stuttering as well, worked flawlessly two weeks ago. Worked fine for months, the occasional dip or load, but not like this.

 

After 10-15 minutes the game starts to stutter. I can even speed up the game and it will stutter at roughly 15 minutes of in-game time. It is a populated mission I've made myself and never had an issue. So I thought I'd just drop the aircraft roughly in the area the stutter start after the alloted in-game time to see what happens.

 

Nothing. It's smooth as ever as when I start the mission.

 

F/A-18 and the Gulf.

 

A mission with just the player aircraft runs smooth of course.

 

Specs: I7-6700k @ 4 ghz, 16 gb RAM @ 2133 mhz, Asus Z270i MB, Geforce 1070, mechanical HDD.

 

Even lowering my graphics settings to the absolutelowest does nothing. I've disconnected my internet, only having mouse and keyboard attached and start the mission with player jet AI controlled instead, and everytime I've the same results. I've even rolled back to a restore point from March 21, and reinstalled DCS. Tried different Nvidia drivers. No change.

 

Other games, like Arma 3, Assassins Creed Odyssey, heavily modded Skyrim, Ghost Recon Wildlands, no problem whatsoever.

 

Have ordered 32 gig of RAM @ 2666 mhz and an SSD. I'm having doubts it'll do anything but...I'll see.
