Stutters - probably not AI voice related

[Yardstick]

I am able to run CloD at a high fps everything maxed out @ 1440 but get really annoying stutter freezes every few minutes or so.  These are generally more pronounced the larger the mission as well as close to the ground and last about a second but can be longer.  I limit my fps to 100 (using nVidia control panel) but can run higher - the stutters are still there whether I limit the fps or not. 

 

The below screen grab was from a flight across the Channel where I was just panning my head around periodically to check my six.  The fps was a solid 100 save for the odd stutter-freeze hence the low of 19. Its driving me nuts, I've had a number of instances when I've been just about to pull lead or open fire on a target only to get a short freeze and the shot is ruined.  

 

The stutters don't seem to be linked to the AI voices (I used to have issues with these in the past on a different rig), I've gone down all the usual routes: setting process affinity, disabling the Steam overlay etc but with no change.

 

Any thoughts?

Something spawing in or out or doing something in the mission like bombing or hitting the ground. Ship also have caused me stuttering in the past as they ping in.  

[Yardstick]

Makes sense - it’s like the stutter you get in the GB career bomber Intercept missions when the position of the enemy group gets updated on the map.  
 

Question then - is there any way to get rid of the stutter?

[Buzzsaw]

What campaign are you playing?

[Yardstick]

Currently III/JG 26 'Schlageter' by Piper-Kiev.  It's heavy on aircraft and other objects but I had the same issues with the GB Redux campaign as well.  Stutters are less pronounced in quick missions but still there.

If you had the same problems with a GREAT BATTLES campaign then I would suggest it may be something in your system.

 

Do you have any other programs running?  Anything which updates to your computer regularly using the internet?

 

I would recommend you turn off those types of programs prior to playing.

[Yardstick]

Sorry Buzzsaw, I meant the CloD Great Britain Redux campaign not Il2:GB (should have been clearer).  The only updater I have on automatic is Windows.  CloD is the only game I have any issues with, everything else runs very smoothly - particularly IL2:GB.

[BOO]

One way to perhaps narrow down its if external or mission related (not foolproof by any means) is either fly the same mission twice and identically to see if the stutters occur in the same place and/or time or fly the simple single aircraft cross country mission included in game to see what happens.  You could also run the windows task manager resource monitor at the same to to see if there is any internet related spike.

 

SP for me is almost jerk free but ive only got the included missions having long since lost any other most complex downloaded ones. In most game standard missions where all the assests are loaded from the start this is some very slight stutter right after the spawn but its smooth thereafter.  Even the ships in MP do not seem to cause the stutter they once did but i may just not be looking. In MP on a non custom skin server, Player (but not AI) aircraft spawning and despawning still produce a momentary stutter. 

 

In the past increasing the max pre-rendered frames to 4 may have possibly helped reduce the impact a little but never really eliminated it. If you have external views you could try scrolling through the assets in the game prior to taking off as this should load the necessary cache stuff for the rest of the mission. My logic on this is that some mission makers use of either full custom skins or the non default ones in the game. I seem to remember both (at least all the custom and  possibly some of the game included skins) ended up in the cache so are presumably transferred there whilst playing (2Mb dds files from using the loadout viewer in game also end up in there but im not sure if these are used in the game or just the viewer. Its one one the reasons I stopped following the advice to delete the cache folder. I nver found it resolved anything grphically and I saw no detremental effect for not doing so. At worst I would delete the shader folder within it following any patch. 

 

When compairing the Dangerdogs server where custom skins and the use of non default game skins were allowed to ATAG where it was default only the stutter on a player joining was noticably less on the latter even in the days where there server was hosting 50-60 players ( wsnt perfect due to spawning/despawning but the stutter was not as persistent. This was down mainly to the use of uncompressed custom skins or skins with limited compression.  I think I did some tests about 2016 with TWC about skins and determined a file size of under 400kb was less likely to induce stutter on a MP server. This is more than acheivable with 2048x2048 skins provided the panel lines were left off the skin (it is not necessary to include these in clod as the game draws them anyway). A scroll through the cache after a session on the DD server would often show skins with sizes in multi Mbs and certainly many more at round 800Kb.

 

Anyhow - probably none of this will help but i hope something in there may. 

 

Good luck

Hi

I am suffering from the same stuttering problem in SP.

I am a newbie to CLoD ( 680 hours ) having flown IL-2 Sturmovik: Forgotten Battles and its upgrades since its inception.

I have nothing running in the background as the rig is for CLoD exclusively with only Google Chrome as my browser.

My missions are mostly self built or expanded from the original or modified from downloaded files using FMB.

Stuttering is random as I have timed them and it can happen during take off, level flight, combat ( most annoying ).... anytime.

It does not seem to occur during spawning or aircraft crashing into the deck because as I said it can occur during take off.

It is not repeatable as, flying the same mission back to back, will have random stuttering ( some take offs are completely clear ) 

My FPS is constantly in the mid 150's to 190's and higher with all settings on max except for Forest (on low ) and Land Shading (medium).

System: i7-7700, MSI GTX1060-3gig, 16gig DDR4, 240gig SSD, Win10, MS SWFF2

 

Any suggestions welcome.

Six hundred and eighty hours in and you're still a newbie?

[Bf109Ace]

Yeah, compared with flying hours on IL-2 Forgotten Battles, ACE Expansion Pack, Pacific Fighters and 1946, where I must have well over 10,000hours, then Yip, I am a newbie.

Hello Bf109Ace

 

Can you record your missions in a track and PM me.

 

I'll give you an email and you can send the track and the mission to me.

 

Also include your system specs and operating system.

 

Thanks

[Yardstick]

My joystick is currently out of action due to a broken x-axis spring.  Out of curiosity I ran an AI controlled mission but didn't turn on headtracking (I use Opentrack).  The mission seems noticeably smoother with no obvious stutters. 

 

It's only a sample size of one and I will have to do more analysis but wonder if Opentrack has caused stutters for others?

Hi Buzzsaw

Thanks for the response.

Help me here as I am not very computer savvy.

I assume you want me to record a mission whilst playing  and "PM" ? you. What is PM?

Interestingly enough, whilst flying a mission this evening, I recorded the intervals of stutter using my lap timer.

It now appears to stutter every 40 seconds or so. previously it was definitely random. Strange.

Here are my system specs so long............

 i7-7700 3.6Ghz/4.2Ghz Turbo, MB Biostar TB250-BTC,  MSI GTX1060-3Gig, 16gig DDR4 2666Mhz,  240Gig SSD, Windows10,  MS Sidewinder FF2

[Buzzsaw]

PM - Personal Message.... "Message".

 

Do you use head tracking?

[Bf109Ace]

Hi Buzzsaw

Sorry for the delayed response.

I do not think I use head tracking?? I read Yardstick mentions headtrack/ opentrack. An explanation please

My problem seems random at times.

Flew a mission unrecorded and plenty stuttering.

Flew the same mission recorded and FLAWLESS!! FPS also the highest I have seen: mid 200's

Flew another mission recorded and flawless again...WTF

Took a day or two of flawless missions before the problem reoccurred

Stuttering definitely has a pattern approximating around 40 seconds between stutters and FPS now down in the low100's

Typically ( allowing for my response time ) 40,1 39,9 40,4 39,7 16,6 23,2 40,4 45,5 34,6

interestingly figures of 16,6 and 23,2 add up to the 40sec and 45,5 plus 34,6 = 80sec again a multiple of 40

I can send you the MIS file and recorded track of a flawless and stuttering mission if required.

Please send your email address

Thanks

I would suggest you have another program running which is interfering with the game.

 

If it was an issue with the game, it would be consistent.

 

Something is making demands on your system at intervals...  a program which requires access to the internet is most likely.

Hi Buzzsaw

You were right.... IL-2 was on my Google browser

Thanks
