@tmz   I ran your mission and I averaged 10fps in VR with Virtual DT.  I'm not that versed in the mission editor but I seen there were over 1300 units for blue and red. How many are moving or active.  Our squad had troubles with moving AI tanking performance in MP and had to scale it back some.  I use the 4ya Syria server as my stress test for VR and as of right now it fine.  DCS is a strange some people 0 problems the others the computer catches fire. I have been on both ends of the spectrum.

Thanks for the testing! This is a vanilla version of a DCS Retribution campaign I use (with all scripts removed), as there is no active frontline there should not be many moving units. What strikes me is the performance difference between 2.9.5, where I am running routinely campaigns of this scale, and 2.9.6/2.9.7 where it is not possible at all.

@NineLine @BIGNEWY

FYI track and log files have been included here, could either of you please confirm these have been sent to the team?

 

[BIGNEWY]

Thank you for the logs I will show this thread to the team.

I have a home system when 2 players can play in MP on a closed system. The mission I have made have been super smooth in 2.9.5. After the last updates the stuttering and multiple freezes make the missions unplayable.

 

Nothing has changed on my side, Gone from a steady 120 FPS in 2D to 30 /70 FPS

 

The second player is glitchy as heck.

My SPECS, Intel i7 8700k, 64 GB RAM, GTX 2080ti game on m.2 drive.

Prior to the update...at the same place in this mission...these lines were both almost smooth, the change is just riduculous

Mission Editor made missions that have been quite happy running in 2.9.5, with large formations, ground units and ships, up to 40+ AI units busy...

These same missions now  Massive Stutters and have Micro Freezes with around 12 AI units involved. There has been a considerable performance crash since the last 2 updates.

I have this feedback from submitted files...How do I resolve this ? and Why has it now become such an issue after last updates.

I dont think as users we should need to deep dive into our systems to keep having to try and recover big drops in performance after almost every " update" . This has never happened in any other Sim I have ever used. Its honestly hurting the experience for a LOT of us. To enjoy the Sim, you should NOT need to be a PC master, or deep dive guru. We are being forced to do this by DCS, and its driving LOTS of people away.

… and those of us that have spent a fortune on it and stay it’s driving us nuts.

I have used process Lasso to get my CORES 7 to 11 running in DCS again....There is a SLIGHT  improvement.

I have a stress test Map on the Normandy Map. I have loaded it with a Lot of extra AI aircraft, it seems to run very well...however other missions with more ground units, for example AAA batteries, are running way worse, with a lot fewer AC airborne. How to pin point where the issue actually lies is really  really difficult.

I know....somehow DCS needs to get its foundations reset...Super new modules are Icing on the cake...but if the cake itself is a mess....no amount of Icing will help really grow the Fan base in a strong and sustainable way..

Another issue, and I really do understand why its super difficult to implement, is some form of relief for Non Americans/Europeans, trying to purchase modules with currencies that are stuffed...mine is currently over 18 to 1...anyway thats another topic.

[tmz]

Tried again yesterday with DCS 2.9.7.59074, still a stuttery mess. Log attached.

Same here, low fps.. After clean update ( Clean Up / Repair and Update.. Fxo and Metashaders2 empty )

I wanted to buy the Afghanistan Map and the F16, but i will wait to see if the performance improves over time..

Bummer...did you happen to clear the shaders first and give time for them to rebuild?

I own every single module except for the Yak-52 and MB-339 and have all the maps, and can't play as of the past two updates. You know damn well I'll never get compensated for any of it and currently I'm helpless just sitting here waiting for a miracle. I can't in good conscious suggest to any of my friends to get into DCS at this point, and have a couple that were going to but when they heard about the Razbam/ED issues and the amount of modules and lack of transparency involved they backed out.

[Archangel44]

On a good note.

I checked and all 8 of my cores are operating and pretty much maxed out while playing DCS.

AMD 9590.

I then installed the latest graphics driver for my EVGA 1080-SC.

Set frame rate max to 70 both in game and on the Nvidia control panel.

In game, set some graphics to high and ultra.

Final word, it’s better, not great but better, less stutter and screen freezes.

ED still has more work to do. 2.9.5 was way better.

[Rene Coulon]

i AM CURRENTLY RUNNING STRESS TESTS on the Normandy map.

1. 200 AI Aircraft airborne, smooth as silk, nothing else

2. 300 AI Ships, zero stutters, nothing else

3. 200 ground unit of various sizes and types including V1 lauchers etc, no issues.

Somehow its looking like a combination of things triggering the stutters, or I am still to isolate the Trigger either a Plane, Ship or ground unit...It could even be a formation type ????

Will report any findings

[DragonSoulkin]

I tried again with no mods to play and here's the result. Track file, log, and a screenshot of the fps drops. THIS IS COMPLETELY UNPLAYABLE!!! Either fix your game ED or give me my money back for EVERYTHING I've payed for. I've been patient and I'm done.

Had the same issue. Mine was caused by the stream deck software running in the background. even when DCS export was disabled..

 

 

Hope this helps someone else from resorting to a hammer. I love you

 

I don't have a stream deck. Never have.

[A Hamburgler]

One thing I have mentioned before but I will again. I seem to notice that everyone who describes the same issue all has this in their logs. 

WARNING WORLD (Main): ModelTimeQuantizer: ANTIFREEZE ENABLED

It is then repeated until ending the game. 

[Slippa]

Whatever’s happening I could do with some antifreeze. It froze up on me three or four times earlier, had to force close it from the task manager yet again.

Sorting out this mess ought to be priority number one. Flying the Chinook on a MP server feels like I’ve got the plague at times, people shy away from the stutter-fest. I don’t blame the Chinny at all, it was happening three updates ago.

It really isn’t funny.

[A Hamburgler]

@BIGNEWY I noticed something. If you look at the graphs and look at 2.9.6 how it spikes about every second. In the log I noticed a repeated message. 

WARNING WORLD (Main): ModelTimeQuantizer: ANTIFREEZE ENABLED

I then went to the log on 2.9.5 and this is not in there. After a little further digging I was going through some of the forum posts with people who described a similar issue as mine. I looked in their logs too and sure enough they also have the same message repeated. 

WARNING WORLD (Main): ModelTimeQuantizer: ANTIFREEZE ENABLED

So what causes this ANTIFREEZE during AI heavy missions in 2.9.6 vs 2.9.5? This causes me to go from 160 FPS in 2.9.5 to 9 FPS in 2.9.6 (also 2.9.7). Might be something to look into.

Interesting I also have to force close my DCS app.

Is this a Mission you have made ?

I think my system is being affected by TEMPLATES made for missions  I run on myclosed home server. Not definitive yet

According to the log-analyzer over on the ED discord, you still have the remnants of a lot of mods in your Saved Games\DCS.openbeta\ folder.

I saw something similar to this recently. Was only getting it in track replays and SP content. Turned out after deleting the OH-6 mod, I still had mod .lua files leftover in the savedgames>DCS>Scripts>Hooks folder. Deleted the leftover mod .lua files (the loaches AI gunner hook lua can cause issues iirc) and that sort of stutter disappeared.

I will say though anecdotal, I've seen lots of user reports of increased memory usage since the Afghan patch (2.9.6.57650) I think as well. I know the patch notes did list changes to the terrain render tech, so it could be related.

I totally agree on this comment.
