Performance issues in missions with multiple ground/air units AFTER DCS 2.9.5.55918

[bojote]

Pretty sure you must be aware of this as its very easy to replicate in ANY computer. Something after 2.9.5.55918 completely killed performance for complex missions. This is not a problem in simple missions or instant action, but clearly noticeable in the late missions of OCN. For example, Mission 16 Part 2. Check this out:

The name of the gif corresponds to the DCS version being used. I can go back and forth between versions and clearly notice how 2.9.5.55918 performs flawlesly. Not a single stutter, incredible smooth performance during the mission. This is 120 FPS limited. 

Notice how starting with DCS 2.9.6.57650 (which by the way, DCS wont let me revert to, I had to go to 2.9.6.58056) performance is all messed up. I believe the jump from DCS 2.9.5 to 2.9.6 is affecting users with complex SP missions or heavy units MP servers. I'm writing this here hoping that you can raise this concern with DCS as it is very easy to replicate. Just load Mission 16 (Part 2) and compare how DCS versions behave. I tried this in my two computers (one of them NEVER had DCS installed) so it was a fresh install, no mods, Just Syria, OCN and the Hornet, thats it.

I understand this is NOT your problem and your campaign is not the issue I'm simply raising this concern with you hoping DCS at least acknowledges there is a problem that will and is affecting users.

 

Thanks!

Hi Bojote, 

we are aware and hopefully the coming patch will improve things, the team have been working on some fps tweaks and optimisations. 

thank you

Thats great to hear Scott! I was concerned that ED would think this was just users complaining with messed up configurations and or mods causing the problem. I do not use ANY mods in my testing PC so I was confident this was something introduced in 2.9.6 in particular with either ground or air AI units as I believe you guys added new AI logic and/or moved functionality to other threads. I'm pretty sure this also affected my A/A radar 'effectiveness' as I was experiencing radar lock drops even in STT mode for contacts in front of me, not maneuvering and both in PRF med/hi. Looking forward to the next update!

Thanks!

Thanks for the post, it is a problem we've all been aware of since that patch hit performance pretty hard.  ED to be fair have been listening from day 1 and I as Scott said have been working hard to fix.  Hopefully we'll see improvements soon.

For me this issue was solved by updating the mist and moose scripts in saved games to the latest releases.

[bojote]

Does mist or moose get installed automatically by OCN? I’ve certainly not downloaded them 

[ChillNG]

No, there is no moose or mist present in any of my campaigns.

Yeah thats what I imagined. I believe some people is probably not aware of the specific problem we are discussing (and that has been acknowledged already) so I'll just wait for the new patch. thanks!

Apologies, I did not intend to convey that your specific mission was something fixed by the moose/mist update I performed; but rather that the general issue (in liberation campaigns or through the inferno) of "2.9.5.55918 completely killed performance for complex missions" that I had noticed myself was solved for me with the updating of the scripts. I don't know if that information is of any value to you or not but every bit helps I suppose. Sorry for the confusion.

Any update to this topic, I too am experiencing frame stutter for all missions in the Campaign so far. It only seems to occur in this Campaign specifically. Other Campaigns e.g. Both Raven One Campaigns I get consistently over 100 fps, with Operation Cerberus North my fps maxes out at around 60 with my 3090 GPU running at only 60% capacity. Stuttering is worst around airfields and turning down visibility and details does not seem to have an effect.
