Game performance, fps drops and slideshows

Recommended Posts

Not sure if I'm the only one (probably not), but the 3.001 update has made multiplayer borderline unplayable for me. 

 

Pre-3.001 it was playable, if somewhat stuttery sometimes. With the new update I get 25-40 fps (15-20 less than before).

Multiplayer turns into a slideshow the moment a plane is <1km away from me.

Microstutters are gone and have been replaced with their older brother: stutters. 

The game is now absolutely beautiful, but unfortunately almost unplayable.

 

Is anyone else experiencing performance issues?

 

System specs:

i5 4690 @ 3.5 

8GB DDR3

GTX 760

Windows 10

 

 

Update: Now have a GTX 1060: Ultra settings, 50-60fps, absolutely divine. But still have stutters.

               So as others have mentioned, stutters are mostly independent of fps. None of the proposed fixes worked, unfortunately.

It seems that many people are experiencing performance changes. At this early stage, it's hard to say what's going on. 

 

Have you tried the graphics settings? They are quite different after the update. 

 

Hang tight. It's likely that these issues will be explained eventually.

Exact same thing here.  Career mode unplayable with same settings as 2.0.  In hindsight I'm not sure why I expected it to remain same, performance wise.  I'm sure render distance and AA play a bigger part now.  I'm going to try to go down to 100km and AA at 2 instead of 4.  I really don't want to move clouds down from "high", but that's likely the next step.  Will report back in 14 hrs.

Jason may have found a fix on another thread.  Turn 4k textures on and check vsync.  Seems to be a stutter that the gpu Biggs down in.  I saw it worst in zoomed modes.

So you're saying that turning on higher textures and v-sync can help?

Nothing helped for me. Still have stutters too. Singleplayer are slighter but at multiplayer is worse. I tried everything, Jasons tips also. Nothing changed.

Yeah I just tried too.  An improvement, but not enough.  Had to run back to work, but later I'll try moving down to 1920x1080 res.  I already put clouds to medium and mirrors to basic with little gain in fps.  I see it mostly when trying to zoom in on a target.

I have been having stutters since a few updates ago (I don't remember exactly when it started), they are worse now though. Its hard to explain but the feel of the game is like I have a marginal FPS (say 30-35) but I actually have 100+. Its worse when I'm looking any direction except straight ahead, but it will happen then also when there is a lot going on. If I look out to the side, into a bank at the ground, there are these little "hitches" at regular intervals. When I look quickly in a new direction it there is a noticeable lag, it actual makes me a little dizzy sometimes. 

 

Another weird thing has started since yesterday, the mission will start with only 24 FPS. I have to Alt-Tab to another window then back to IL-2 to get it "unstuck".

 

All I do any more is try to fix this issue, I haven't played a mission for enjoyment in the past few months.

Same for me. It happens sporadically and only alt+Tab helps.

 

And i have a crash problem with the P39 when activating the HUD. Is there anybody with the same problem? It happens only with the P39. As soon as i press the HUD button the game instantly crashes?

I’m trying with terrain details distance to normal and 100km instead of 150km. 

 

I tried with 130km and x2 terrain details and got 25fps and before the update I had around 50fps.

I'm still getting 60 fps but terrible stuttering. unplayable offline or on.

 

Tried lowering resolution and settings but it makes no difference. At first I thought it was the return of the FFB plus trackIR stutter problem but when I turned off FFB it made no difference.

 

Boy am I disappointed right now. 

 

I5 3.7 gighz

16 gig ram 

GTX 770 8gig

 

It was running solid 60 fps with no stutter before in highest settings.

I set a lot of the settings at medium (can't remember the exact settings right now) and that helped alot. I haven't tried on a really populated server, just the Coconut Normal server because WoL doesnt work for me.

Anyway, steady FPS at 120-144(v-sync on) and no stutters.

Specs:

i5-4670k
8gb ram

gtx970

Running of SSD

Anybody know what’s taking the most ressources and what they changed other than distance visibility?

 

Someone online told me the clouds are taking much more than distance, but not sure. I always played with the highest cloud setting and medium mirror and normal terrain rendering. Before I had 60 FPS easily, but now I’m around 26-45 FPS. I tried to change distance from 150 to 100km, but not a lot of difference. Also tried rendering distance 2x and normal, but hard to see differences with all settings out there hahaha.

I've been having some issues myself and I've been trying to find the culprit. I think I may have narrowed it down.

 

Jason's recommendations for lowering your settings, Full Screen mode OFF, VSYNC ON, and enabling 4K textures seems to sort out a lot of the problems I was having. I discovered tonight that VRAM requirements have apparently gone up a lot. The terrain rendering in the distance seems to eat up a lot of extra video memory. If you, like me, have a 2GB card, then this may just be too much for the card to handle and it starts stuttering even while the rest of the GPU pipeline is doing well.

 

Most games do not demand VRAM like flight sims. The requirements now seem higher.

Tomorrow I will start at the lowest settings and will go up step by step until I see what’s causing the drop.

Hopefully these performance issues are temporary. It's quite difficult to try and match pre 3.001 graphics quality without inducing stutters and fps drops. It can be nauseating during violent maneuvers specially when tracking and engaging targets. 

 

The Career missions seem to have a lot of units too. If I recall correctly Rise of Flight had an issue where too many units on screen at one time would slow down the simulation. At a recent escort mission I attempted the number of bombers and my own squad pretty much put me at near 1/2 simulation speed, major stuttering included. This was on "scattered" frontline density as well. 

 

Prior to 3.001, running at Ultra would net 50-60fps very well even on dense ground attack missions (unless the HUD was on, then it drops to less than 24fps). Right now turning the HUD on and off would induce stutters, place a permanent "shade" over the screen (as if wearing sunglasses), and reduce FPS by a substantial margin. Downgrading to High from Ultra makes little difference in the Campaign. If anything the Campaign on lower graphics fidelity just looks worse off with minimal FPS improvements. 

 

These are most likely just growing pains coming from the new update. I really hope there would be post-patch performance improvements down the line. This is a huge update and one that I am most excited about and very grateful for. 

 

Right now I can't quite stay in a flight too long without feeling a bit sick. Consistent stutters and 1/2 speed running can be pretty jarring. I'm mostly limited to QBs at the moment, and even then there are some pretty hefty performance hits. 

 

I might have to wait until performance gets stabilized, maybe to pre 3.001 levels. Those were some very optimized builds and having the content of 3.001 alongside that experience would be bliss!

I have no stutters but with scattered density option my rig is not fast enough. Game is slow as hell at the target location.  I switched to high from ultra, reduced horizont and object visibility, lowered shadows and clouds and its still not enough. Today i will try balanced settings and reduce the horizont even more.

If the problem with performance has to be with the CPU, that is being overloaded by the new IA and the amount of units present, the graphics settings will do little to nothing to mitigate this, it is not a GPU load problem. Maybe the render distance and other similar setting can slightly aliviate this by lowering the amount of load on the render thread, but not too much.

At least in my case its not the CPU being pushed to the max. It's not even most of the GPU that is having an issue (otherwise the frame rate would be dropping quite a bit) but rather the VRAM filling up. Another test of this is that I'm seeing stutters (when not using some of the techniques suggested by Jason) even when there are no AI in a mission.

 

Also... its AI. Not IA. :cool:

Well... I tried different settings and getting always the same number of FPS. I tried lowering shadow quality, cloud to medium and landscape distance to 70km and still have around 29-40fps.

 

Maybe a better optimisation will fixe everything.

 

How to actually lock FPS to 30? With Vsync on I still have 30-40fps.

 

——

Edit: ok enabling v-sync in Nvidia Panel and removing it from in-game setting + locking to 30 FPS remove the lag for me since it’s constant.

 

Now I just have a problem with clouds making lot of aliasing to my plane...

I'm not really sure if this is the golden solution to the stuttering problem, because

I'm only affected when flying online - offline performance is nearly the same for me.

I just bought a GTX 1060 for £180 ($290, lucky bargain) so that's my solution to the problem.

 

Cloud settings seem to have a considerable impact on FPS, as do shadow settings. 

It's a strange combination of stable(ish), relatively low FPS (compared to pre-3.001) and micro stutters when close to enemy plane(s).

 

Jason's VSync on, fullscreen off suggestion has made a minimal difference, but nothing considerable.

I have a pretty good system (i7-7700K @ 5.0, GTX1080Ti w/11 Gigs VRAM, 16 Gigs 3600 RAM) and I still have a major stutter issues as I described above.

 

I don't have this stutter problem with any other title on this rig.

 

I don't think its just matter of insufficient hardware.

Exactly my experience.

I've read and followed Jason's instructions but still a 50% loss of fps.

After going back to my initial settings but lowering Clouds Quality to Medium helped a lot.

The trade off is that clouds in the distance look kind of jagged. :dry:

I usually don't have any problems of performance but in some particular places (with a lot of AI) my GPU load falls to 80-85%, and my CPU load isn't maxed in either case. In other games, for example, I had a CPU bottleneck although it wasn´t showing 100% load on all cores

For the VRAM I can say that it has a higher load. I'm hitting the 3Gb mark but it is not reaching it's max for my 970. What I have seen is that AI for me and the Campaign overall has a higher load on the CPU. 

 

Before the update I was near the 2,8

No fps problems here, they are exactly as before the update rock solid at 60. I can reduce but not eliminate stuttering and microstutters that are prominent in career and even qmb. I'm sure this will get worked out by the devs. Too many reports to suggest otherwise.

Hi :

 

Just having same issues here. Pre patch the game was running on max setting verry nicely ( around 60-100 fps). Since patch ; i'm experiencing stuttering and micro freezs too ; especially in campain mod.

 

In 1v1 fast mission  it looks like  no freez but still 20 fps  are missing.

 

Havn't tryed out MP for yet.

 

I'm runing the game with a i5 4670K (Haswell)@4.4 gHz ; 16gb of ram and a GTX 980 in 1920*1080. Drivers up to date and latest version of Track IR installed.

What I would like to understand is why in the new career the game stutters and goes into that slow motion mode when my rig is maintaining a solid 60 locked fps in all situations. It doesnt matter what settings I turn down including the new distant horizon which I have tried cutting back to the original it doesnt change anything, the stutter and slow down in the career is still there. Even turning on or off the HUD or map causes freezes or stutters. Now clearly my 3820 I7 is long in the tooth but its clocked at a totally stable 4.5 ghz and paired with a 1080 sc2. 

 

I would suspect maybe the cpu is causing stutters and slow downs if the fps were not completely consistent at 60 no matter what is going on in the game. Maybe it is causing it even though the fps are solid but I don't know enough about it to say. Seems like if the cpu was having trouble keeping up with things it would show in fluctuating fps with big drops when things get busy but that is not the case.  

 

This was a huge undertaking by these talented devs and I remain sure they will find something to do about the problem since so many are experiencing the same or similar issues on a wide range of rigs. Here's to hoping!

When I record my mission in the career mode (which was slow due to a lot of airplanes and other units) and replay it,  replay is absolutely fluid with lot of planes and I suppose with ground units. So whats the problem? Why in the career I have slowdowns?

Maybe BOX need a control track to gauge performance like the "Black Death" track in IL2-46 that anyone could load up and get their FPS to compare with others.

 

I have to admit, I have no complaints about performance. (Nor have had any over the years... :cool:) I'm getting 50 to 60 almost all the time, 1080p, graphics maxed or close to maxed, 8 to 16 planes in the air in the QMB, on an i5-6500/1060 3GB/8GB RAM/SSD.

Prior to this update this game ran like a dream. Everything ultra 3440x1440. Now my frames have halfed in areas and stuttering is common.

 

If im close to AI plane in combat it causes frequent stutters. Airborne i would be at a rock solid 100fps regardless of cloud density or ground density....now im struggling to hit 60!! Ive reduced the new distance settings right down and its making little difference.

 

The clouds appear to be hitting my fps hardest. On clear settings things are better but cloudy settings really hit hard.

 

I hopefull it will be tweaked to bring it back how it was.

I can confirm this, I also noticed this behaviour. And seeing your system informations in the footer I'm totally puzzled

that you have the same trouble like me. But I'm running a old gherkin...

hi,   there is another setting that make a big difference on my system

i got all setting to high or ultra with the 4k option with AA to 4x and -  but  (nvidia driver texture set to (high performance) with trilinear optimization to ON)  , and i got high fps, no stutters anymore, i did the same career mission few times this morning , just switching this texture setting from high quality to high performance, and i had constantly same results, stutters present or not at all. (4k option must be on too)

In career mode, i can still have few stutters at the beginning, pretty sure it is cause by all mission info loading in background, cause after that everything run smooth even with many friendly and enemies AI around .

by the way... i dont know what setting i touched but planes in front of clouds look a lot better now

i guess it is because I dont use the grid super sampling like i used to do , i got the ingame 4x AA combine with the nvidi inspector set to enchance with MFAA on, and transparency multisampling to on, and planes in fronts of cloud are ok now, they must be inside the cloud to look bad, i guess it is the MFAA combined with the ingame MSAA.

 

ps:i m not show off i just try to help, so be kind or say nothing please

 

bomber were just little over the clouds

i can see the plane way better now

Hopefully this proves to be insightful, Lemon.  I'll test your settings in a few hours.  Would you mind taking a screenshot of your Nvidia settings and in-game graphics settings so I can replicate?

Yep - this would be very kind of you, Lemon. Did some testing with your suggested settings and

this seems to resolve a lot of trouble - but on MP still a lot of stutter, particularly on crowded servers.
