A lot of planes a lot of stutter

[smink1701]

I have a pretty good rig but I've noticed lately when Im in SP missions and have six or more planes in the air I get a serious drop in FPS.  I have been able to run pretty smoothly in the past an was wondering if something has changed?  I have always been able to max graphic settings, ie Ultra, are their some things I should do to improve performance without sacrificing too much gfx quality?  Thanks!

The new campaign also made me want to figure out my graphics settings.

The first thing I noticed is that the larger minimap caused some stuttering. When this didn't fix my low FPS, I tried to lower the graphics settings. For some reason, my FPS didn't increase when I lowered it unlessI changed some of the stuff in the tick boxes on the right.

I ultimately found out that V-sync was cutting my FPS by 10-15 frames.

 

I hope that helps.

I get a serious drop in FPS

 

What I notice with this Game Version are 1-2sec stutter. With other planes or without i get it.

Not sure what it is? Need to find out.

Performance in IL-2: BoS is a tricky thing. I had a 5 year old system and I blamed it for some of my performance woes but I've got a brand new Skylake Core i5 system with 8gb of DDR4 and a GTX 960 and everything else I play on this rig runs incredibly smoothly. BoS with a couple dozen AI flying in the battlesphere around the player and I see the performance really suffering.

 

I've done a ton of tweaks but I think it comes down to the engine, the physics, and the AI. BoS pushes systems like nothing else out there and while I suspect there may be room for improving performance on the engine side of things I also think its a bit like IL-2 Sturmovik and Lock On: Modern Air Combat when those came out ages ago. It'll be years before systems will have the horsepower to truly be able to run these at maximum.

This is also happening on MP .

Yup, running on ultra or low just don't mean a thing to my rig. Well, maybe a difference in 3-4FPS(!). But if I untick HDR and SSAO I can really notice the performace increase. Another way I improved perfomance was to overclock my CPUs, put my CPU-fans on ultra (and boy, do the fans have to work hard) and strangely enough I changed my general settings for my Nvidia card to balanced between performance and quality. That worked!

But I think it's pretty damn strange that if I turn down/off everything, I still only get 45 FPS. I don't have my rigs specs but it produces silky smooth framerates in Rise of Flight and DCS. WITH HIGH SETTINGS.

Completely disagree. Until a few days ago, i had a 4 year old graphics card (Amd Radeon Hd7950), and i could run BoS 60Fps+ all the time, no problem. Everything maxed out of course. Back then when it was still possible, i even had the terrain.ini maxed out (like some crazy high number), and also had 60Fps+. My rig: i5 4670K, 20GB memory, HD7950/Gtx 970

I think for a sim, BoS is not very demanding. If you really wanna see demanding sims, look at DCS 2.0 or Arma3. Not even the Titan can handle Arma 3 on everything maxed out, while my 4 year old AMD could run BoS maxed out.

Play some campaign missions for a while. Find a situation where there are 30-40 aircraft in your area of contact at once and tell me that you're still getting a solid 60fps. BoS isn't a graphics hog ... its a CPU hog.

 

I haven't run DCS Edge yet. Is it even out?

BoS is limited by CPU when a lot is happening,  good GPU is not relevant

pray the next patch will contain optimizations 

[Urra]

For some reason the devs seem to have included a lot of calculations for the ai pilots in the planes even when their not visible on the screen. I honestly dont care if every ai pilot has to wipe their nose every 30 seconds, its unessessary overhead calculations most could do without....6 he111's bring my computer to 15 fps, other planes have less impact, but its still unessessary and just plain silly.

There are internal discussions on optimisation for non-player aircraft, and the devs are currently working on how to do that without porking anything else up.

Nice, glad to hear. Huge AI bomber formations in multiplayer servers is what this Sim is still missing

At least one of my fellow users complained about the game performance whenhe recently tested it on the same laptop he uses to run DCS World without problems, and X-Plane 10.

 

In my old i5 2500k @3.2GHz, and a GTX 960 4GB card, it is as smooth as it has ever been - perfect smoothness all of the time.

 

I seldom play SP missions, but use mostly the online servers, and even with plenty of aircraft in a furball, there's no lag at all in my rig.

 

I have VSync disabled, as well as HDR and SSAO, and 2x visibility range, on HIGH settings.

No tearing? I just cannot disable VSync

you should set Vsync off and full window on, that's how you get rid of the tearing

I tried 8 Heinkels, it turned into a slideshow

Exactly that!

[6./ZG26_Gielow]

I think there is some kind of leakage on the game code.

 

Sometimes I get solid 40fps on the ground and 60 flying.

 

You launch the same mission again and fps drops. Really crazy.

[steppenwolf]

At least there's no one ranting about how the human mind can't perceive the difference between 60 and 30fps. Soooo, I guess things have changed...somewhat?

You can definatelly notice the dif between 30 and 60 fps, very easily.

You mean windowed mode off, right? Anyway, I have a lot of tearing, even with full window. (never tried the other otpion)

 

It's not normal the fps fluctuate like crazy with half a dozen aircrafts around. Well, I never considered 6-8 planes as a lot of planes. I could expect problems with 20-30 aircrafts and high ground activity.

Try telling that to a console player xP

 

I got FPS problems after the "tank patch" - before it i played on ultra and after - tweaked the setting to "balanced"

On the early builds of the game for some bizarre reason I had worse performance with FULLSCREEN on. With the same config I had better fps with windowed mode. But I didnt test with the latest patch...

I am so glad somebody raised this topic also for SP. I also have some stuttering in SP ( 1 or 2 seconds as Super said) especially with IA crossing from left to right or otherwise in front. Thankfully the community has provide great inputs  across various forums.

 

I have done..NVIDIA control panel, power management, turning off unnecessary processes, in game graphic setting and lowering in game bitrate, running msi to see where the problems is.

 

One of the best "tweaks"that I did was to check full screen in graphic setting. For some reason that improved FPS enormously.

 

My CPU is no slouch: http://www.game-debate.com/hardware/index.php?pid=2060&cpu=Core%20i7-4710MQ%204-Core%202.5GHz

 

Kind regards A.

Best thing i tried so far is driver 360.60 nvidia. No SLI, no vsync, full screen, and monitor at 60hz. Most importantly, starting program il2.exe directly from folder, without the little splash screen that checks your version for updates. Also set startup.cfg max fps to 60. why....? Not sure. My theory is the last driver hotpatch allowed my gsync to work the way it was intended to.

Clouds also have a bigger hit for me than before, but maybe it is not actually the clouds per se, but that they now have a bigger/more noticeable impact due to lower overhead

 

As has been said and experienced with previous patches, I hope for further improvements, they are aware of performance hits and seem to constantly work on optimising even if it is not mentioned 

 

Maybe, in a perfect world one day, we will get added features and performance increase in the same patch
