Severe stuttering

[Pokredde (POK)]

Hi,

 

I really hope to find the cure for this:

 

I'm experiencing pretty severe random stuttering on my brand new system Win10, I7 7700@3.7GHz, GTX 1070 and 16gb DDR4 2400hz ram (no overclocking) one single 120hz NT monitor.

I have almost tried everything including disabling hyper threading, reducing or removing civilian traffic, disabling antialising, closing antivirus, Steam etc. Nothing seems to help and when flying online the stutters (sometimes up to 1-2 sec.) make it 100% unplayable. Both on 1.5 and 2.1 alpha.

Windows is running on a SSD and my games is installed on a internal SATA HDD.

 

My old trusty pc with i5 2500k, GTX770 and 10gb ram (no SSD) never had any issues with stuttering but my brand new $2.400 pc is struggling.

Especially when loading terrain while turning or flyby or when other planes is visible.

 

My fps in 1.5 and 2.1 is about 40 in avarage even on medium settings which I also find a little dissapointing?

 

I have just ordered Oculus CV1 and are very concerned with the low framerate and stuttering issues.

 

Any good suggestions?

Install the game on your ssd will benefit a lot for loading i think,... and overclock the cpu to 4.7ghz normal the i7 7700 would handel that easy, and dcs need singel core performance,

But i dont think thats the major problem... i think start with ssd and clean drivers

Drivers are all up to date.

Unfortunately i don't have enough free space om my SSD (it needs some minimum amount of free space) :noexpression:

But my old HDD never struggled?

Try disabling hyper-threading or (I can't remember the actual name) clock speed reduction in bios. I had pretty bad micro-stutters (a slight hiccup every half second) and disabling hyper-threading made it go away. I then tried turning off that variable frequency thing with hyper-threading left on and it had the same effect. I had both of them off for a while but there was no real benefit to have them both off so I turned hyper-threading back on.

 

DCS only really uses 1 core and so my guess is the way it was being managed leads to stutters when the work load switched from 1 active core to another idle core, which is running at a lower clock speed until it gets the new load. Maybe half the available cores means they don't have a chance to go into the lower power/clockspeed mode.

 

If you are talking about larger stutters I'm not sure it will help as I get that every once in a while in multiplayer severs, but that might be a netcode thing.

 

Edit: I'm not talking about turbo when I say disable the "variable frequency thing". I mean a feature that drops the idle clock speed to like 1Ghz from 3 or 4 or whatever.

Is you NVIDIA activated?

[Burning Bridges]

Can you tell me what reducing the preload radius to 100 would do? I found that the higher the value, the more the system tries to load, and with the minimum value the system actually runs better.

 

In the long run, you will benefit greatly when you move the game to a SSD. I would also suggest following the various guidelines about making your HDD faster, disabling indexing and so on.

Let me explain... 40 fps with an NVIDIA GTX1070? No man, that should not be. I have a high feeling your NVIDIA is disabled!

 

Also, 1 - 2 second stutter, that is possible, but only when it is loading from the HDD, not from an SSD. And only in the beginning. Try to set the preloading radius to maximum. that will load all, and will reduce the stuttering as a consequence of scenery loaded from the disk.

Also, If you haven't done so, its usually a good idea to go to Saved Games location and remove options.lua file (from "Config" sub-folder) plus contents of "Fxo" and "Metashaders" folders after every major game update. That gets rid of old shader files and gfx settings and resets the game to stock state gfx-wise - a good cleanup habit, which might solve some performance issues.

It's a little hard to make that statement without knowing what resolution he is playing at. I have a 3440X1440 screen and I get 60-100fps depending on the situation with a 1080. If he's running 4K that's very possible performance.

 

Also, if this is around a lot of AI then 40-60 fps could be due to CPU bottleneck and there is absolutely nothing that he can do about that.

 

I really doubt his "Nvidia" is disabled. There is no way he would get 40fps with integrated graphics. The GTX 1080 is 1381% faster than the 630 and there is no way I'm ever going to get 552 fps at medium settings.

[David OC]

What resolution are you running Pokredde?

 

You pretty much have a similar system as me, not the K version tho:(, this HERE will give you a benchmark of the performance you should be getting close to in a large mission. Try those settings too and see if it's any better for you.

Have already tried turning Hyper threading of - it didn't help.

I'm not sure I know what you mean with variable thing?

Yes, I'm pretty sure. Will double check tomorrow.

I will make a test with a radius at 100 tomorrow. Though I have already tried to mess around with the radius setting.

 

Installing DCS 1.5 and 2.0 on the SSD is unfortunately not possible at this stage. I will look up some guidelines on optimizing HDD's.

 

I have seen suggestions else where about symlinking only the needed files to SSD and keep the rest of DCS on the HDD. But I'm not sure how to do this.

I think 40 fps is wierd too...

Will try increasing the radius tomorrow :thumbup:

It's a new intallation on a new pc, but will give it a try tomorrow.

Sorry.

I should of course have mentioned that I "only" run the game at 1080 on a single monitor.

I have tested a 60hz and a 120hz gaming monitor and there was no difference regarding the stutter and framerate.

 

The average 40 fps in DCS 1.5 is flying 100% alone (free flight) and clear blue sky :cry:

In DCS 2.0 it's a bit higher though.

 

It's getting pretty late here - I hope it's okay to get back to you when tested above suggestions as soon as possible tomorrow?

[Dingo_Bob]

you could also make sure you have a system managed page file set on your SSD, turn it off on the HDD I find DCS stutters more if set to run on my HDD's

 

Also try setting CPU affinity to 2x cores only using an autoexec.cfg instructions in this thread - https://forums.eagle.ru/showthread.php?t=118535&highlight=cpu+affinity

(some say it's placebo, some find it makes a difference, guess it may depend on the individual system)

It can be tried, but that could be bad for the lifetime of your SSD. I would try it (running for a short time is not gonna hurt either way) and if it helps we can think of a better solution.

SSD and overclock

[Pokredde (POK)]

Hi again,

 

I have now tried to reinstall 1.5.x and 2.1.x on my SSD (C:) instead of my HHD (D:) It's well over 100gb size hurts on my little 256 gb SSD... But the stuttering seems to be gone.

 

Regarding the framerates nothing seems to have changed.

It's still avarage 40 fps on medium or high settings in DCS 1.5.x

 

Actually messing with the graphic settings doesn't change the fps very much for me?

 

Maybe the low performace is related to that my CPU or GPU doesn't run at near full power when I monitor them while running DCS? Sometimes <50%.

(I have set my CPU management to 100% and performance in MSI Control Center to "sport"

 

 

you could also make sure you have a system managed page file set on your SSD, turn it off on the HDD I find DCS stutters more if set to run on my HDD's

[Sideslip]

The game won't use very much more than 1 CPU core. In my case with 4 cores and 8 threads that means about 12-20% is what I usually see. If a lot of stuff is going on that % doesn't increase but the FPS do decrease. Usually (but not always) you will see CPU stay constant and GPU usage decrease indicating a CPU bottleneck. The only thing you can do is to increase clock speed. If you are comfortable overclocking, a 10% overclock results in 10% more fps when CPU bottle necked. Or from 40 to 44 fps. Not huge, but I have a 25% overclock which is a much better increase.

 

If you haven't already, turn off traffic. Little cars driving around is really useless and actually uses a lot of CPU power. View distance is another big CPU consumer. In some games lowering shadow quality actually hurts fps as it unloads the complex stuff from the GPU and instead has the CPU calculate simple shadows. Unfortunately I can't help too much without actually being there to turn stuff on/off for you.

 

And no, CPU affinity doesn't do anything. Maybe on really old CPUs or windows vista, but that was from a long ago era. You'll get a bigger fps boost from making sure "calculator" isn't running in the background.

[Sideslip]

Actually I don't think it is the SSD but rather the game being on the C drive. Sounds stupid I know, but I had a problem I won't get into explaining right now that was solved by moving the game to my slower C drive.

Ok, when you are running this game at 1080 on a single monitor, I guess then 1920 x 1080 and you get only 40 fps, that is WEIRD, when you are using an NVIDIA 1070 GTX!

 

Can you do a test, and make a single player test mission.

Fly in a zone without buildings etc. On the 1.5.7 version totally in the north of the map, there are no objects there. And us ALT-PAUSE to check the framerate. Use PRT-SCR (when running DCS) to save screenshots. The screenshots should show the frame rate in the upper left corner. The screenshots are saved by DCS in the user/Saved Games/DCS/Screenshots folder. Upload them using www.imgbb.com. Then you can include pictures in this forum using the forum TAGS, imgbb provides you facilities to do cut-paste these tages with hyperlinks included.

 

Also take a screenshot of the DCS graphics settings panel. You can also do this using PRT-SCR and upload from the Screenshots folder to www.imgbb.com.

 

Open your NVIDIA configuration panel. There is an option in the menu Desktop, that allows you to add a pictogram icon in your taskbar to show the GPU activity. Run DCS and click on the icon. You see DCS mentioned in the list?

 

Run a dxdiag and attach to a reply in this post.

 

Sorry, but 40 fps on a 1080 NVIDIA resolution is SLOOOOW.

I run here on my MSI the sim 1.5.7 on a 1920x1080 resolution on an NVIDIA 880M and I get 60 fps in crowdy cities, clear skies, high settings.

I have tried following your instructions and I get from 50-110 fps up North on the map.

Seeing your settings, turn off Civ Traffic. It's a waste of CPU performance (which is in short supply) for nothing. Also reduce water to medium. All high does IIRC is add better terrain reflections which you will rarely see and that costs a little bit of GPU power. And I would reduce the Rez of cockpit displays. That can be a big performance hog when using a weapons targeting system as the game has to render a second view, applying AA and AF twice. The rest of your settings are similar to mine.

 

I'm using ultra for my view distance, but in areas with lots of units and buildings you may get an fps boost (via cpu load) by dropping to medium. I wouldn't use low though.

 

If you want to have a better idea whats going on, I'd suggest getting Afterburner and using the on-screen display to see your fps, total cpu usage, gpu usage, ram usage, vram usage, and cpu/gpu temps. It really makes it easier to tune your game settings when you know what is limiting your performance. When setting up a new game I change 1 setting at a time and note cpu/gpu performance change and fps, and then decide where I can obtain the best quality to fps balance. A 3 fps difference 10 times stacks up to 30fps, but changing a setting to remove shadows for 1 fps, or reducing gpu load from 80% to 70% are not worth it.

turn HDR off for more fps as well

Usb headphones

 

I have been plagued by random i intermittent 1 to 2 second stuttering despite a high pc i7 7700 ssd 980ti 32gb ddr 4 3000hz......

 

What fixed it for me is to not use usb audio dongles but to plug head phones straight into audio jack.... i have logitech 633 usb only can... plugged in is stutterfest.... unplugged no stutters.... different headphones into 3.5mm jack... all is well... consistently reproduceable on my pc....
