Stutter whenever someone else hits/destroys a plane in 2.5.1

[backspace340]

Since I installed 2.5.1 I've noticed a really annoying issue that's occurring in both SP and MP for me. Every time someone else shoots an enemy plane, there's a period of 4 or 5 seconds of 1FPS stutter (and I play in Steam VR so it takes me completely out of the game).

 

It doesn't happen when I shoot an enemy plane, only when two other parties shoot each other. I figured it was just a MP bug, but I played a quick SP mission today with AI planes on both sides and every time they shot each other I got a stutter. I've got essentially a top spec rig - i7-8700, 1080ti, 32gb 3200 ddr4, M.2 Nvme SSD (960 Evo), and I've not had this problem before 2.5.1 as far as I'm aware. It doesn't seem to affect other players when it affects me.

 

Has anyone had anything similar or have any potential solutions? What would help troubleshoot it - I'm not crashing so don't have any relevant logs, let me know what would be useful and I'll try and provide it.

Your not alone, I experience this as well. It's not a hardware issue and there's no software or notepad editing you can do to fix it. This is a ED thing, and until they ditch the nice new planes and maps and focus on the quality of gameplay it's not going to happen.

 

For me SAM sites really expose the problem, but I still get the stutters even without them. It depends on what canvas you fly on as well... Caucasus = the best performance, Nevada = a close second, and Normandy = forget Normandy it's ****in horrid.

 

I didn't know what stutters were until DCS World haha.

 

BTW I play 1080p with OpenTrack, not even VR.

I think I've worked out what's causing the lag - it happens when loading the 'damaged' model of whatever's been destroyed. You can see it twice in this clip (of my atrocious driving in the TF51) - it happens once at the very beginning of the clip, when two other players are fighting and one dies, and then - most clearly of all - when I hit the truck there's a big pause while the truck model is replaced with it's damaged version:

As you can imagine, lots of stuff dies when playing DCS so this is really detrimental to my gameplay. Any solutions would be much appreciated!

The newest beta of 2.5 with the new memory manager, I'm sure ED is looking at it very closely.

Not quite true, just that the team working on the new engine and implementing multi core/vulkan, got the short end of the stick here.:D

 

Many of the maps and models are by 3rd parties and other teams would move forward with other tasks, not wait for the slow coach multi core/vulkan guys.:)

 

DCS and many of the flight sims were never designed for VR from the start and DCS is one of the hardest sims to do VR in because of what's going on in the sim compared to anything else out there. Vulkan will hopefully change much moving forward for US and ED's future. I don't see anyone else out there pushing this way, even the large Lockheed have only ever updated their licensed engine and haven't bothered to try and build there own.

 

They just need a little longer to get to a level with the new 2.5 merge, so the beta and stable versions are moved apart a little bit more.

any new model being loaded in gives that. Weapons fired, things destroyed, planes spawned.

You can alleviate the obvious ones by placing models of anything that might spawn, into the game already. Especially crucial MUST-DO, is player aircraft, put the static version somewhere in a corner of the map.

 

For the rest, well, fast texture loading and hard disk speed alleviates this.

This is new to 2.5.1 for me - never had any issues before in either earlier versions of 2.5, 2.X or 1.5 with this. I also have a m.2 NVME SSD drive, it's not really possible to get a faster hard disk.

Yeah I think it's related to that - hopefully they'll see this and tweak it for the next patch.

Yes i have this too, unplayble in VR because its so annoying. Just bought normandy, the assets pack, and the dora so you can imagine how chuffed I am!

[backspace340]

This is still an issue in the new open beta build released this week.

[Zarma]

Heavy issue when long range SAMs are fired like SA11 or destroyer SM-2

[backspace340]

This is still an issue after the new mini-update. Is there nothing I can provide ED to help diagnose the issue? Do you know about it already?

[Chief1942]

Interesting issue. I have been flying a ground attack mission in Normandy where both air and land assets are tasked with destroying Third Reich ground units. It appears that when either air or ground units destroy them, and the destroyed unit changes from functional to destroyed, I get some short but noticeable "stutters". I can't recall if I had ever noticed those stutters before. Perhaps you guys are on to something. I am NOT computer literate enough to source out some of the causes of the stutter issues. Good luck in your pursuit.

[JIMJAM]

I am also now getting the dreaded micro pauses. The old familiar "cannon burst" pause and also been noticing other explosion related ones.

These things are sure pretty but not at the expense of immersion at the peak of a event. Same with the touch down pause many sims have. Wish I could turn all that fluff off.

[backspace340]

This has killed me twice today - its really ruining my gameplay, what's the point of doing anything when a 10s freeze will just put you in the ground? Clips of it happening again below (warning some swearing, because this is very frustrating):

I've had three crashes today, hopefully one of them has some info about this issue - i've attached the crash logs. I did see stuff like this in the logs, maybe pertinent?

Edit: Only one of the crash zips is under 10mb, so have attached that one. Will see if I can host the others somewhere.

Is anyone checking their ram usage? I had to throw another 16Gb in my machine to stop the pausing as all of the first 16 was being used up. Are all of you running Intel or are some of you running AMD? Be nice to see if we can verify whether this may be hardware specific.

[backspace340]

Four more deaths today caused by this bug, I ran a repair today and no difference, I don't run any mods either.

I don't think it's a RAM issue - I've got 32gb of DDR4 3200 RAM.

Those clips were MP right? Are you noticing the same issue in SP? Is there a place in a A-10c quick mission that the issue consistently reoccurs for you? I could load up that same mission and see if I can duplicate the problem.

While I have noticed at times the HMD drops to the steam load room while playing online; it is usually a lag that everyone on the server experiences but doesn’t necessarily correspond to a vehicle destruction event.

I usually fly on the 104th, 99th, and aerobatic servers. I’ll be flying tonight and will make note of the timing of the pauses if they occur.

Like this thread states, loading new models or damaged models seems to a big issue. This log attached was a mission to destroy a single TU-22. These two lines right here occurred in the log towards the bottom upon splashing the bomber.

 

2018-05-20 14:40:37.115 ERROR GRAPHICSVISTA: Can't open model TU-22-OBLOMOK-WING-R.

 

 

 

2018-05-20 14:40:37.119 ERROR GRAPHICSVISTA: Can't open model TU-22-OBLOMOK-WING-L.

 

"Can't load" models = stutters? I'm sure this has been looked at (I hope anyway), but when creating a bigger mission with multiple "splashes" it's unplayable at times.

 

I'll refuse to buy any more content until stuff like this is ironed out. I encourage others to do the same. Until then I'll enjoy my solo sunset flights.

I have the same problems from December and they didn't fix, I am starting to think that they are pretty limited in resources.

I tried to play with 32 GB (200$ more) and I have the same problems.

I am running I 7700K, 16 GB ddr4, Nvidia 1080ti, game running on ssd nv2.

I've tried to get a consistent reproduction of this in single player - it seems to only affect certain planes. For example, in the M2000C fast action 'Missile Combat' mission, I get a big freeze whenever the M2000C's are hit or damaged, but didn't notice anything when the Su's or Mig29's got hit. Looking at the logs afterwards, I saw this again coinciding with the freeze:

 

2018-05-23 00:02:14.075 ERROR GRAPHICSVISTA: Can't open model M2KC-fragment-nose.

2018-05-23 00:02:27.662 ERROR GRAPHICSVISTA: Can't open model M2KC-fragment-nose-1.

2018-05-23 00:02:27.663 ERROR GRAPHICSVISTA: Can't open model M2KC-fragment-tail.

2018-05-23 00:04:31.690 ERROR GRAPHICSVISTA: Can't open model M2KC-fragment-nose-1.

2018-05-23 00:04:31.698 ERROR GRAPHICSVISTA: Can't open model M2KC-fragment-nose.

2018-05-23 00:04:34.929 ERROR GRAPHICSVISTA: Can't open model M-2000C_DESTR.

 

It's definitely affecting some planes more than others - I get big pauses when the M2000, Harrier, A-10C, SU27 and SU33 get hit, I didn't notice any with the Mig-21 or SU25.

This is still a problem in the current version of Open Beta. Every time a missile hits a target the game freezes for 10-30 seconds.

 

Additionally the game lags in the lobby when I join a server.

This seems to be better in 2.5.2 - I played today and didn't seem to get the stutter anymore when something's damaged.

[Gryzor]

Stutter is related to loading textures of objects destroyed I believe, or loading effects, maybe it could be preloaded in memory for those who have high end PC

Agreed!!!!! My wished have come through!!!! I noticed I was playing an insane amount of DCS this weekend and was wondering what had changed and then I realised the combat is actually fun again!! Adds so much immersion!!!
