Stutterfest aka Carrier - WHY???

[ironk79]

Just stopped my next carrier attempt since i upgraded my system - what a disappointment.

I have flown carrier missions on my old 4690k, gtx970, but the performance wasnt great, missions were boring repeatitive ju87 nanny missions that took ages because ju87 goes about 32mph and i eventually stopped playing carrier.

Recently bought Kuban, did mostly QM and PWCG, but was itching to try a new carrier  - first mission Kuban, Bomber Escort, P-39.

Right from the start a stutterfest 45- 70 fps, mostly 45ish when bombers and other wingman in sight (10 small dots in the distance - wow!). Formation of 10 bomberrs, 6 escort planes, flying straight, no action, no nothing.

Cpu jawns at 25%, one core maxing at 76% at one time, gpu somewhere at 65% and still stutterfest- why? this is not acceptable, this kind of setup with the settings i am playing (tweaked low, ss 80%).

Wont go back to carrier again, this is just to depressing. i never played il46, but i have seen videos, formation of literally hundreds of bombers filled the sky, still smooth gameplay - where did it go so horribly wrong? given what this game cost, this big chunk of content isnt even usable?

I go back to QM and PWCG, carrier is dead to me. Will also question buying future content, at best with a good discount, sorry.

I assume you mean "Career" rather than carrier?

 

I would check couple things first.

 

1: Try a clean install of the Nvidia drivers. Use DDU in Safe Mode ( with internet disconnected) to completely remove the drivers.

Keep internet disconnected when reboot the PC. Install the latest Nvidia drivers, only installing the driver and PhysX. None of that other stuff.

Now reconnect the internet.

 

2: Be sure and set in the Nvidia control panel, for BoS - " Prefer Maximum Performance".  It is set to "Optimal" by default.

 

You should be able to run the Career pretty smooth with your rig.

you are right dburne, of career makes more sense.

i really appreciate your help. Just tried your tips, fresh install of display driver, started up career, still the same. the bomber escort missions is stuttering like before, CPU and GPU usage also limbs somewhere midfield.

Doubt its a problem with my machine or setup, but a problem deep within the game. it also makes no sense when approching my airfield, fps also frop hard, just because of a few AAA batteries sprinkled across the airfiled? No, sadly performace doenst match what is actually presented ingame, there is ablsolutely no reason why it drops down into the 50s when following a dozen bombers, or flying over your own airfield with no action at all. Its quite sad and frustrating.

[dburne]

Yeah that makes no sense at all, I have a much older rig with exception of GPU and get very smooth performance in Career over Kuban.

 

What do you have in game graphics set on?

Also have you made any graphic adjustments in Nvidia Control Panel?

Are you running any Mods for IL-2?

I would not think one would want to run with vsync in VR.

I am running very low settings, shadows low, 100km, landscape normal, no AA, only HDR, nothing demanding really. Nvidia settings are standard, only perfonce mode enabled.

Tried with mods on and off, last setting i tried was mods off, balanced.

presets. I can run QM with 8vs4 over the mountains of kuban, no problem, PWCG minor occasionally drops.

But in career, flying over my airfield, looking down on to it already induces horrible frame drops.

dburne - do you have smooth frames over airfields in career?

Something sure seems amiss.

Yes I was getting smooth frames over airfields. I flew through two complete Spit Kuban Careers without

any major issue. However it has been a few weeks now since flying Career as I have been flying a PWCG campaign, so don't know if anything has changed with any of the latest game updates in regards to the Career.

 

Have you monitored your GPU utilization and clocks whilst flying low over airfields? For some reason in this game I get low numbers when low over airfield, taking off and landing as well. GPU clock not boosting and GPU utilization around 30% when low over airfield. Only this game I have observed that in.

I will try and start a new Career later on today and check if I see a noticeable difference over what I have gotten previously.

 

My inclination would be to tell you to get rid of any mods and check it with no mods installed to see if any difference as the next step, but let me check on my end first and see if I experience the same as you are. Will report back later on today.

GPU was low, 30% could be about right , i also tried without mods, balanced settings, no difference. i dont know if something in the background conflicts, SteamVR and OTT settings like ASW, Steam Reprojection. So far i allways turn those settings off and i get 90fps outside career most of the time.

Its really odd, AI and ground units really impact performance for some reason.

I do not make any settings in Steam VR for my Rift. I set it to just manual with 100% display.

I use the Oculus Tray Tool to set my SS and ASW to off for IL-2.

 

Got a doc appt this am, will check on my end for Career when I return little later on.

In Steam VR - at least after first start (or after pc crash, when steam/steamvr sometimes completely resets itself) i have to disable the settings  asychronous or interleaved reprojection. if i leave them untouched, i get stutter and barely 90fps in any kind of scenario.

I've also made a bug report about career FPS drops in the bug section. There is something wrong with it, like there used to be before it got fixed, steam VR basestation flashes all over the place. It's not the fault of my computer just an update that messed things up. Scripted battles and campaigns work fine. Career needs some fixing.

[Wolf8312]

Another thing on PWCG or scripted campaign motion smoothing is running brilliantly, smooth and fluid as a normal game, no matter where you look or how you move your head, with no ghosting of planes or artifacts. Career however as soon as you load it on the runway there are propeller artifacts all over the place!

[dburne]

Ok just flew a complete mission in Spit Kuban Career.

4 in my fight, and we intercepted 8 bombers - JU 87, and 2 109's flying cover for them. We also had some significant cloud coverage.

 

I can say, performance does not seem what it used to be in Career. I was however able to maintain 45 fps on runway and down low, it dropped to like upper 30's very briefly while landing  a time or two, but stayed 45 fps for the most part. I fly with ASW off. The entire mission was smooth for me.

 

One thing I have noticed of late, this game is not utilizing my 2080 Ti as I would hope. GPU utilization is very low, especially down low. Mine is around 28% and the highest I saw during the flight was like 38%. Nvidia Boost is not going to kick in with utilization numbers that low for the most part, which contributes to the problem I am sure.

Heck I checked my Precision X1 log after  the flight, and the hottest the GPU core got was 45c.

I only saw my GPU reach full boost briefly a time or two ( 1980 Mhz). Most of the flight it ran 1350-1500 Mhz.

 

If you guys have monitoring software, you should check that and see what you are getting when you are getting the stuttering.  I am also getting the above numbers in my PWCG campaign, so in my case it is not just Career I see this in.

My other games (VR), my card runs at full boost consistently.

 

I think there is something going on now with IL-2 in VR. Would be interesting to hear if monitor users see GPU utilization numbers this low.

That's an absolute joke, something is terribly wrong, I would assume the cpu isn't able to feed that monster gpu. You should jack the SS up as high as you can and see what it does.

Well I would think that too, except IL-2 is the only game it does this in now. None of my others do this, I get full boost out of my GPU consistently along with much higher GPU usage numbers. Plus I have already cranked my graphics up pretty good with no drop in performance.

I am not much concerned with it any longer, it is certainly flyable now and smooth. Plus I am already gathering the parts for a new build I should have done here in the

very near future. 

 

I would be curious to know what GPU clock speeds those that are having the stuttering are seeing when it is occurring.

Something is really seriously wrong for me! Strange thing is PWCG and scripted campaigns are smooth as butter. But Career, and even quick mission generators are totally FUBAR. I'm getting FPS that I have never even seen in this game on this rig before, like below 45 and they are jumping all over the place! But good news is I mainly fly scripted campaigns or PWCG.

Can any of you that are experience this report on what your GPU Utilization and GPU clock speed numbers are showing?

On runway getting ready to take off, my GPU Utilization is like 28-30 % and GPU clock speed is 1350 Mhz. ( no boost)
 

[ironk79]

i am flying at the moment over my airfield behind a few il2, 50- 60fps, CPU 20-25 %, , gpu between 50-65%, 1920mhz

Over airflied with bombers in the distance (10 x A20+ 4xP39) fps 50 ish, GPU 40%, CPU 30ish %, 1920Mhz

 

on the airfiield standing , looking towards AAA, same figures. not locking toward AAA -  90fps

No Mods, SS 100  Steam VR, balanced, shadows low, landscape 2x, no AA, HDR, 150km, in other words nohing crazy at all

 

QM with a 4vs4 over Kuban Forrest with clouds gets GPU 99%  to easy

Those certainly look like some pretty good numbers.

 I need to do some more testing on the campaign and QME, but on PWCG on a mission with only 2 enemy bombers and a wingman, my GPU wasnt even exceeding 45 percent.CPU about 23 percent. That mission was very smooth though!

I'm actually really hopeful that when devs do get this fixed that IL-2 may even be perfect with MS. Probably getting my hopes up, but its great on scripted campaign and PWCG so far.

Update- on the quick mision editor it goes up to about 50 percent which is ludicrous giving how the performance is terrible. CPU about 18-20. But these missions still not taxing at all they should have much better performance.

8GB of RAM isn`t huge amount, specially if it isn`t running at the 3200 it`s rated at.

 

Have you checked in bios that you`re RAM is running at it`s full capacity and not a (non-XMP) 2100mhz (or similar)?

 

You may have already checked these, just thinking out loud. . . .

[ironk79]

althogh 8GB isnt much today, i have never seen usage of more than 6gb while flying. The stutter only occurs when having bombers or AAA from arifiled in sight.

You have an awesome rig yet you stuck with 8 gigs of ram, it may only say 6 gigs of usage, but that's only 2 gigs left for wiggle room, game could be writing to your page file and then you will get stutters, 16 gigs is the minimum I'd recommend to anyone these days.

[ironk79]

16gb def. wouldnt hurt, but with the blown RAM prices these days, i am not that impatient to go for 16gb. i rather went for faster RAM,maybe later go for additional 8gb

 Also,  PWCG and S-Campaign run 90fps, no problem. I dont think the cure for the stutter that plages me ist more RAM.

 

BTW, i upgraded my old PSU (500W) that  i had swapped from my old setup, since i got occasional shutdowns and bad stutter before that (probably CPU running dry) .

Went for a 650W instead, no problems so far, and it feels like fps are even more steady now.

lol a 500 watt psu especially a cheap one is far too underpowered for your system, you are probably pulling 200 just from the cpu and another 300+ from that gpu. I am running a really nice seasonic focus plus gold 750watt which has been excellent. Got it for cheap too. It's one of the highest rated psu's on johnny guru's psu review site, dude knows literally everything there is to know about power supplies. Never cheap out on em. Even 650 is a bit low for your setup.

Just one basic question regarding RAM: Do you have one single stick of 8Gb or two stick of 4Gb?

[ironk79]

2x4GB, but i really doubt RAM size itself is the cause of this issue

I'm having exact same problem. Much lower fps then before in career and Qmb. No Idee whats happened. Mabe some optdate in oculus rift/home is the problem?

 Well I'm on the Vive myself mate so thats probably not it! It was a problem I had with 3.002 that later got fixed, but a new update has come along and brought it back again, with a vengence. It never used to affect Qmb though!
