And another stutter thread..

[TAW_Blaze]

Long story short, I was fairly unhappy with the FPS I had with with my old rig and decided to get a new one. Now I have nice FPS with nearly maxed settings but it stutters a lot. Even on reduced settings the stutter is still there. :(

 

Old setup:

4690k

evga gtx980

16gb 1866 mhz

 

New setup:

ryzen 3700x

strix 5700xt

32gb 3200 mhz

 

2x sata SSDs, win10 on 1, DCS on the 2nd

 

custom page file set for 32gb on win10 ssd

samsung rapid mode running on the SSD with DCS

no OC

 

dcs settings:

everything high, except:

shadows: med

visibility: ultra

terrain shadows: flat

msaa 2x

trees/grass max

2560x1440

fullscreen

 

In general fps ranges between 50-120 depending on where I am, however lots of stutters and especially after 2.5.6 a lot of complete freezes a few secs. The worst part is when you try to zoom in on something quickly in a hurry and you freeze for 3 secs.

 

I've spent some time trying to figure things out with performance / resource monitor and it is showing some SSD spikes however I've not been able to get any tool that monitors ingame performance and system resources together so it's pretty hard to correlate them. So I'm a little stuck in terms of what to do.

 

A couple possibilities I've seen / thought of but haven't tried:

- disable track/acmi writing: https://forums.eagle.ru/showthread.php?t=263567

- disable hot plug: https://forums.eagle.ru/showthread.php?t=251377

- relocating DCS to the same SSD as win10

- cpu affinity black magic (is this still something that works?)

 

I'm hoping someone else has more ideas that could work. :helpsmilie:

That feeling, when you spend a fortune and DCS runs not much better or even worse than before...

 

MSI Afterburner is a (free) good tool, to see what's going on, with live graphs of fps/framtime etc. but it needs to be set up, which data it has to show.

• First I would try to rename your open.beta(or stable?) user folder and start with fresh one. Just to exclude, that there is some crazy setting/edit, mod, plugin, that causes your problem.
   
  
• Then I suggest to tick/untick Fullscreen mode and try alt-Enter in both settings and see if something changes.
   
  
• What monitor (max. refresh rate) do you have? Don't you experience tearing when frames go up to 120? Frames all over the place would make dcs stutter with me. So, vsync/freesync is also needed (eventually also caping frames(*3)).
   
  
• And the theres also all this windows stuff, like disable gaming mode, gamebar/xbox overlay, setting your power plan to maximum performance, disable fullscreen optimization for dcs.exe, exclude dcs game folder from antivirus and more. (I also tried the cpu affinity thing (incl. process lasso), but it didn't make any difference with me, but you can try (*1))
   
  
• I would switch Samsung rapid mode off until you solved your problem. It uses ram to cache data. As you have 32GB it shouldn't be a problem but who knows... (*2)
  

 

It's all I could think of right now.

1) this would be weird, but can try it later on

2) I used to run borderless but that had even more stutters, using fullscreen helped a bit. I tried alt enter too but it's not really doing anything from what I've seen.

3) 144 hz, I think I used to run vsync but I have it off atm. Generally I don't hit 144 hz

4) I'm using the Ryzen high performance setting. I think game mode is disabled but will double check.

5) Ok.

[Cornelius]

Ok. Didn't expect you had a 144Hz monitor.:doh: Obviously the Vsync advice is then useless.

 

I want to add since you have a new system: I don't know your skills and I'm not the expert myself, but the first thing to do is to check if the components are running correctly(everything connected right, drivers, Bios settings, windows settings). Are other (demanding) games running well? Have you ever done benchmarks(*) (e.g. CPU/GPU performance, access times/transfer rates of memory/SSD's etc.)? Everything within the normal range?

 

I would go through your own proposed solutions afterwards

About Ryzen high performance setting I found this (*2) it's about core parking issues ,but then all Ryzen people would have to have such problems as you??

 

Hope you can solve your problem.

 

EDIT: Please note: 2.5.6 has introduced performance problems in many cases. So maybe it's better to test your new system with 2.5.5.

Anyway, glad I'm not the only one griping about stuttering in 2.5.6 :)

 

I have a decent rig, and framerates are great, but the stuttering sucks! Fix it ED!

 

Honestly, aside from the improved night lighting draw distance, I don't really see any improvement and the sim now runs poorly. Shadow draw distances are actually worse, giving the maps a rather bland look at altitude. That sucks because I really liked the older version of the sim, and got it running relatively stutter-free for quite a while.

 

Not any more, back to Stutter City!

(*)If not: You can download this tool (https://www.userbenchmark.com) and do a benchmark, which can give you a good overview over your components performance, in relation to others.

I've ran some furmarks with stable fps no issues when I got it.

 

Sadly not really possible to test in 2.5.5 anymore since there isn't any big MP servers running it, in SP I generally have no issues.

[BitMaster]

Strange indeed.

 

Either use MSI Afterburner to see what's happening when you freeze -or- lock it down to say 45 fps to exclude overheating the GPU and see if that helps.

 

If not the heat, other suspects are LAN devices ( does it also happen when DISCONNECTED to LAN ), Virus Scanner exceptions set ?. Exclude the whole DCS folder and also Saved Games\DCS folder.

Seems like it's similar to the thread I'm writing about, 7 PM right now, maybe i'll finish it tonight, midnight ... hopefully earlier.

 

Thing is, the thing I'm working on, we can't solve it our selfs I'm afraid, unless some trick is found but that's pointless it's easier/faster for an official remedy.

[TAW_Blaze]

I don't want to jinx it but it seems like reducing the pagefile to 16 from 32 seems to have done it.

[Worrazen]

I don't know, that seems really weird that would help anything ...

 

About my theory (and evidence) for the terrain stuttering ... I got caught up in the Black Smoke saga so it got delayed.

[TAW_Blaze]

It depends, maybe if there is more pagefile available it'll tend to use it over RAM which would hurt a lot. After 2-3 hours of flying it started some stutters again, but alt enter x2 looked like it fixed that after. I have to test more extensively though.

I'm quickly becoming the "Malwarebytes causes stutters!" advocate. For me and many other players this was the cause; disabling Malwarebytes or excluding DCS from it fixed any stuttering issues.

 

 

You seem to have figured out a solution for your rig, so I'm hopeful it stays that way.

[ac5]

No Malwarebites or any other anti virus here, only the one internal of Windows.

Never problems. Solid 60 FPS fluid like butter!

[TAW_Blaze]

After a week or so they have been back again. Exclusions are on, tried the fps limit but no effect whatsoever. I ended up reducing visibility to high but still stuttering quite badly and often locking up to multiple seconds.
