PERFORMANCE ISSUES and frame rate issues.

[VBF-12_Stick-95]

Noticed today that stutters persist. My game currently stutters everytime someone is killed on the server and the message box tells me that so and so killed so and so. This happens when my frame rate is steady.

 

I wonder how much of hesitations/stutters is related to the air/ground kill chat info in mp?  Is there a correlation?

Hi I also have shutter's and low FPS on the deck and sometimes the terrain texture flashes like a stroboscope. I try everything that I read or know. I am running it at 4K res, R9 295x2, window 7 and the new Crimson drivers.

 

I've try so far .

Lowering my res

Vsync off and on in game of on the Crimson APP

OpenGL on and off

All the Radeon Crimson setting to AMD optimize on and off

Frame pacing

Frame limiting

HDR on and off.

 

 

Some maps are ok some are simply not playable. Looking for someone how can help me fix that.

I saw a post on TrackIr forum, that there is a bug in trackir software. The bug causes trackir to lower graphic cards clocks. They are working a fix. Maybe this is causing problems for some.

These might help get a better performance, but don't expect miracles. The game runs in the same engine as ROF(in Dx9) so it IS still goingo to use some CPU and NOT use 100% GPU.

so this update has brought me new issues. 1 when i go into view mode and i pan around my aircraft and trees and building come into view it begins to stutter reallt badly. espeacilly when i fly low to the ground. any ideas on how to fix this and why this is happening? specs fx 8 core 4.0ghz, r9 290 with 4 gigs of vram, 16 gigs of ram for my system windows 10. help please

Try turning off the default Turbo mode in bios on your FX 8core it has been a well known cause of stutter for many people,

 

also try setting distant landscape detail to 3X at 4 it is a big performance hit, as BoS is heavy on CPU and GPU calls, when the CPU is taking strain, it also has to feed all info to the GPU, when it cannot do this and let your GPU do its work you are CPU limited, I am sure this is the situation you are experiencing

 

Try running Fraps or some other FPS counter to see if this is a framerate dropping issue (going below 30 at stuttering) or something else

My low altitude performance took a hit after the 1.107 update. As a solution I'm now running this with a custom resolution of 2200x1238 instead of 2560x1440. Seems to help a bit. I hate it when you need tweak your settings after every patch to keep it smooth.

[Lusekofte]

After this patch I had to put my settings from High to Balanced, I must have strucked a lucky shot on my settings tho, because I only got a few scenarios I got micro stutters. 

However when I got a enemy close by, not a friendly . My TrackIr acting up a little, WHY? 

But since the mentality of the game is pretty fps I have no intention to upgrade my system. 

As I can see it I need a much better CPU and a relative cheap GPU. People fly without a problem with a 970. 

 

I got a i7 2,8 16 gb RAM with a gtx 680 running Win7

i turned turbo mode off and i did not change performance even when i set distance landscape to zero. i guess its dcs for me now for a while. any other suggestions??

Did you update to 5.3 from 5.2.2 version for track ir? I did last night finally and its a lot less stuttery.

[jafa]

Im happy to find this thread , as from the end of last year I thought my all or part of my rig was about  to pack up , fps and landscape stuttering is now abysmal , i hope the devs are taking notice of this thread as this problem was minor during the middle of 2015 now since the last two  updates it is very pronounced and  judging by the amount of people experiencing the same fault , should be a priority fix even if the game has to be rolled back to patches.

Jafa, can you please share your settings (PC and in game)? We begin to have some experts that could perhaps help you set your rig with the right settings to have the more fluid experience.

Devs are aware of the problem and we hope that when they will build the game in 64 bits it will get rid of a lot of those performance issues!

S!

[Urra]

Hmmm, the info about trackir is interesting,.. I'll try rolling back to an earlier version. But, I think I recall having issues even when not running it.

Chief, I meant the newer version is better for me.

This might have something to do with Nvidia drivers aswell. I had old drivers (351 or something like that from last year) and TrackIr was not downclocking my card. When I updated my Nvidia drivers to 361.75 TrackIr is downclocking my card.

I have observed some micro stuttering too when version 1.04 was introduced. It was offline in single player, and it was slightly different from what Mastiff has in his video - in my case the stutters were less dramatic but more frequent. While I was able to find a workaround that works for me, I still think there is an underlying issue that will need to be looked at, so I'm glad to hear that it's on the agenda.

 

Here's a description of micro stuttering, my setup and observations, and my workaround.

 

What is micro stuttering?

Micro stuttering is a variation in the time it takes to render each frame (https://en.wikipedia.org/wiki/Micro_stuttering). For a graphical representation, see for example: http://www.tomshardware.com/reviews/radeon-geforce-stutter-crossfire,2995-3.html. The framerate can still be high because it is calculated from the average time it takes to render frames. Micro stuttering is mostly observed in setups with multiple GPUs, but can also occur in single GPU setups.

 

My setup and observations

Until recently I used the following system:

- CPU: AMD 1055T @ ~2.85GHz

- GPU: ATI Radeon HD 5870 (1GB)

- RAM: 16GB

- OS: Windows 7 (64bit)

All components were about 5 years old. I was using the latest Radeon drivers from ATI. In hindsight this system seemed to have a good balance between CPU and GPU power. Over the winter maps of BoS (with graphic settings at normal, 4xAA, HDR on, limited to 60FPS), I saw framerates in the low 30's over rural areas and down to the mid 20's over the smoke of Stalingrad. More AI would cause occasional hiccups. I did not notice any micro stuttering (which is why at that point I didn't even know the meaning of the term).

 

When version 1.04 arrived, I experienced a bit of micro stuttering when taxiing on the new summer maps, and when flying very low. Since I was planning to upgrade my box anyway, I thought this was a good time. So I upgraded my CPU, but (scroogily) kept my old GPU (for now). My current setup is:

- CPU: i5 4690 @ ~3.9GHz

- GPU: ATI Radeon HD 5870 (1GB)

- RAM: 16GB

- OS: Windows 7 (64bit)

My BoS graphic settings were still the same: normal, 4xAA, HDR on, limited to 60FPS.

 

Guess how surprised I was when I discovered that the micro stuttering was now much worse than before! Didn't I just throw in a much faster CPU? That's when I started reading up on micro stuttering.

 

Here's my hypothesis: The new fast CPU was pushing frames to the GPU faster than the GPU can process them. Sometimes the GPU could not render them quick enough, which caused little some frames taking more milliseconds to render, as described in the above links. My framerate was around 35 fps - this appears to be the limit of my trusty 5870.

 

My workaround:

After trying all kinds of things over the course of a few days, and when I started to understand the concept of micro stuttering (from the above links), I finally thought: Well, if my average fps is 35, and I get micro stuttering, then the stuttering frames might be just a little slower than 35 fps, maybe around 30 fps. So why not just limit my FPS to 30? And, voila, that did the trick! Framerate locked at 30 FPS, frames are rendered rock solid. And large numbers of AI are not a problem thanks to my new CPU.

 

Now this worked for me, with the unbalanced hardware that I currently have, and it works by sacrificing a few FPS. It might not work for others, and I might encounter other variations of micro stuttering as soon as I upgrade to a better GPU.

 

Thus I'm glad the devs are going to look into this.

 

Did any of you ever try throttling FPS back to 30 FPS? Foe me that did the trick - ever since I've been able to enjoy smooth rendering. Don't get me wrong - the underlying issue should still be addressed but in the interim 30 FPS seems to work fine on rigs like mine.

[CisTer-dB-]

Way too slow for me, I get motion sickness when it's in that range unfortunately. Thanks for sharing your trick m8. 

[CisTer-dB-]

It's already been a few updates and no improvements, do we have an acknowledgment of the proplem by the dev?

[FuriousMeow]

Performance has increased for me.

[No_85_Gramps]

Performance has increased for me.

This was my perception also, need some more flight time to really tell.

 

 

Updated: SP does seem improved, however in MP still lots of stuttering.

Not for people using 2560x1440p. What is the deal I tested using a single 980ti & dual 980ti's & the ancient API will hit 30fps 40fps 50fps 70fps, up & down. I even tried 60Hz vsync & it would not even stay within 60fps. I guess I just need to build a less super computer to run this game? See my hardware specs in my sig, it is more than enough to run this game at a solid 60fps with either a single or dual 980ti GPU. Giant sad face! And I still keep thowing this company money & have not been able to enjoy the sim since the beta.

Really? Because I'm using 2560x1440. Single 780Tis and Dual 780Tis.

 

FPS fluctuates with all games. Especially depending on how many objects are displayed on screen. You want a consistent fps, you need an environment that is never changing.

 

Fallout 4 goes between 45fps and 300+fps, guess that "ancient API" is at fault.

Hello guys, back after a long time.

 

Did not flight for a long time (since 1.105 in fact) because of performance issues. Must say I was quite disappointed ... I never paused the games for such a a long period since 2006 old IL-2 (until 1.105 I was flying almost everyday)  

 

I must admit that my flymate and I noticed nice improvement regarding the stuttering in the last two patch 1.106&1.107 compared to the bloody 1.105 Thanks correcting it and listening to our feedbacks.

 

As of today, I would say that perfs are "acceptable" but fluidity still lacks on a big MP populated server with more than 64 players. Dogfighting in very populated area is still painfull.  IMHO this is related to both memory issues and network coding and we hope devs will keep up the good work to improve  this point. Cheers

Hi Guys,

 

is this micro stuttering again!? For me felt, yes!  wtf

Wings of Liberty is not a good test for anything. That server is always having issues. Needs some maintenance. Just now, no scores being recorded. Engaged two planes, shot them both down, no stats update, landed and told me my flight was cancelled in the summary. Nothing new with that server.

 

If you are having multiplayer performance issues on that server, it's probably that server.

I have it on SP quick mission also low fps, shutter and ground texture flickering

Maybe you are right but unfortunately this server still regroup between 40% up 60% of the total MP population ... that's a real issue and a concern for the future of the game. BOS does not handle more than 64 players in terms of "acceptable" performance at this time, that is why I prefer flying on less crowded but much more immersive servers like 72AG DED random Expert Server.

That is because Fallout 4 is a console port and was locked at 60fps when it first came out. BF4 is very graphic intensive & I can get a solid 100fps @ 100Hz Ultra settings. The sad thing is even on low settings the sim performance is crap compaired to how it used to be. Going from 2x 290x's to 2x 980ti's did not help on performance with BoS/ BoM but did help with every other game I play. Maybe the devs need to dev up a benchmark for this sim like the black death bench for BoB.

[Dakpilot]

problem is DX9, Battlefield is DX11

 

with DX9 only two cores are available to feed GPU's calls, when CPU is taxed by physics/FM/AI two 980ti's cannot be fed quick enough, the bottleneck is CPU caused by (comparatively) inefficient DX9...at least if I understand correctly, am far from an expert..

 

reason for huge performance increase in DCS change to (now outdated) DX11

 

see this test for a direct comparison of a scene from DX11 to DX12 with same hardware..do not have relevant test for DX9

 

 

obviously not entirely relevant but it shows the principal

Meow!!

[FuriousMeow]

Battlefield 4 was also actually a port back to the PC - and while "graphically intensive" (to an extent, it does not have the same visibility distance or size of terrain), it is not even close to CPU intensive. There is very little going on CPU wise because it is still a very basic game. ArmAIII would be a better comparison in terms of overall system utilization - and I notice no one here EVER goes on about how well that SIM performs because it taxes the system heavily and has a lot more CPU calculations going on.

 

Dakpilot, I have never heard of that two core pipeline limit with DX9 - and I can't find any information on that. Can you provide a source for that?

Maybe you are right but unfortunately this server still regroup between 40% up 60% of the total MP population ... that's a real issue and a concern for the future of the game.

So you are saying that the devs need to focus on fixing a single server that is possibly misconfigured? Or perhaps, players should use a different server. I find MUCH better performance on other servers with the same numbers. It is not the fault of the devs for the players migrating to a flawed server, but a fault of the player base.

As much as you don't want to hear it or accept it, it's most likely your system then. Most likely those AMD cards. AMD is not well known for their drivers. nVidia assisted the devs, AMD didn't.

Switching from AMD to Nvidia did not fix any game performance issues. Its not the drivers it is the engine, it is outdated code & they keep trying to feed it.

 

Have you seen how much the DCS world engine has gained in performance since they ditched the DX9.0c API & went with DX11?

 

Old article but the info is still relevent, scroll down & read DX9 limitations.

Well if I don't have issue with any other game/sim at max in 4 K, can you explain me how can it be my system? CloD also use DX 9 with a 32 bit and it is mostly smooth. Don't get me wrong I am sure you want to help. But look at my sigs and tell me without laughing that the problem is on my side.
