investigating 2.8 loading textures takes a loooooong time.

we went from 2 secs texture loading to around 30 secs or more. This can´t be sign of the time changes.

Agreed.

No matter what I do I can't reproduce this in a custom mission

Closest I got is with every single aircraft spawned in a single mission and it takes 3-5 secs to load textures

In MP it takes 30ish secs to load 

Seems like it's limited to MP

Edit: I noticed that when I enter mission editor the map takes a while to load which I also noticed in MP. If the game loads the bugged part in mission editor it might explain why I can't reproduce the bug in SP

I don´t fly MP right now. Yes, i use a lot the ME (i create all of my missions) and same issue, takes awhile to load the map textures in the ME, before 2.8 it didn´t happen, at least didn´t take DCS so long to load a map in ME.

I'm also experiencing very long texture load times with the current beta.  I also noticed roughly a 5-10 fps performance hit across the board... which equates to roughly 10% on my system.

Same. 
Could a fix be that the game loads more before we get control ? 
So "press play" Just means that and not a million things still loading

To my test,2.7 need less than 2 sec from click "fly" to full load the terrain and model.2.8 need 5 sec and more.

My settings not change,same with 2.7.DO NOT TELL ME DELETE THE 3 FOLDERS IN MY GAMESAVE.

The important,my PC hardware not the bottleneck.

Please include your dcs log.

Updated to version 2.8.0.32937 yesterday, mission load times on my system have degraded further.  Finishing a mission and moving to another mission on another map also observing increased load times relative to the previous update.

Confirmed on my end, load times additionally increased by a few seconds on avg

[bukizzzz]

Something has changed in the last patch drastically

Just updated game + drivers so idk which one fixed it but im getting 5 secs load time on the server I used to get 30ish secs, and my avg fps is up from 45 high 20 low to 70 high 30 low in VR

Don't see anything related in the patch notes so im confused now lol

[iQyThradz3137i]

Wonder if Mods have any updates from developers about this or are they still investigating. I mean its not like its Game breaking or anything just weird that even M.2 SSD and SSD have this problem

[silverdevil]

i noticed today that the paginating in layers happened in ME while viewing the loadout in the F-16. it really does not bother me. just adding to the evidence for informational purposes.

[AJaromir]

I wonder to know if that's problem or feature. Because in unreal engine the asynchronyous texture streaming like here in DCS:World is very common. The advantage of limiting resouces to load textures is that there is reserve for other tasks, so the game will not freeze so much when the textures are loading. Also the texture streaming saves quite a lot of memory. Put texture loading on "second rail" was IMO one of the best ideas to reduce ammount of freezes while loading.

dcs.log

Since the reply was not 'we are aware of this' I will second the observation that render layer and/or texture load in times are definitely much slower for me in 2.8 as compared to 2.7 when jumping into a 'Client' slot cockpit (and in mission editor and in-mission maps for that matter).  Anecdotally I'll note that folks in my wing complain about this too.  For whatever reason it does not seem to happen with a 'Player' slot (perhaps happens in the background).

DCS log attached (freshly repaired unmodded DCS Open Beta, normal shader cache locations had been cleared out after latest update -- deleted dcs.log, launched DCS, loaded the map in the ME, launched the map, slotted into the F-16 client slot and waited for the image to appear normal, exited game, attached the dcs.log).

This was done on a mid-range machine, but it takes about the same amount of time to fully render the cockpit image on my 'beast' machine that I normally fly with (4090, m.2 gen4 SSD, etc).

(screenshots were taken on a subsequent run as not to influence the logs, but demonstrates what is happening on screen during the 5 seconds that render layers / textures are loading in)

@BlackdogThere's a thread about this issue in performance bugs section of the forum and that one got "investigating" tag at least, so we've got some reaction from devs. Every extra bit of data helps, though.

[silverdevil]

also a video so the time it takes from picking a slot to textures finished loading can be noticed. this issue does not seem to affect every mission.

Video for loading textures.

Just happened to me on Tempest, 50 players present, mig-29A...

Same issue on GS...

So it is not about which server, number of players might be a trigger, or specific air frames.

Nope not related to players I run 7 servers on different maps and they ALL do it , even with me as the only client.

Which livery?

Does it happen for you every time? (For me sometimes, it can be on and off even on a single server)

For me it doesn't matter what livery I use (all default ones) same ones I was using in 2.7 and didn't have this issue. This is definitely since 2.8 was released.

[_UnknownCheater_]

Same here.Big diffenrece between 2.7 to 2.8.

My post can merge. @BIGNEWY

Loading slow

I can reproduce the issue, but I'm not sure how we can debug this one. We first need to understand why some have it and some don't.

In SP missions where there is no slot choice (instant action etc) then it's an instant texture load, if there is a slot choice then it takes about 3-5 seconds to fully load the textures.

In MP I've seen it take 10-12 seconds.

Spec is in signature running with high texture settings.

[MadKreator]

Mine is hit or miss, sometimes say in liberation or DCE on any given mission everything will load right in. Some missions will take a long time. In MP on say Flashpoint-Levant with a half full server, loading on to a carrier in the av8b takes a long time, every time, several ending in crashes. But I cannot reproduce the texture load issue otherwise, consistently,  to point to an airframe, map, SP or MP. It was definitely not a thought in my mind in 2.7 The longest lag may have been 5-8seconds. But in 2.8 I have experienced up to 15-20seconds sometimes. Its usually quick enough that its not worrisome, but it is noticeably more across the board. Once they’re there, everything runs smooth as can be. I run world preload fairly high so I suppose that can be part of it too with the new clouds and calculations associated with them.. maybe

Does posting a log file or track when it happens help anyone out? I don’t imagine this is something that can really be shown in that way. But if there’s any system info, logs, game logs etc to provide, I’m happy to share.

Try picking a hotstart slot on this mission: https://www.digitalcombatsimulator.com/en/files/3321127/

Reproduces for me every time - takes a while for MPD, external aircraft and ground textures to fill in and become visible.
