Mission editor slow

[AEthelraedUnraed]

Since a couple of weeks (quite possibly since the last update), the viewport of the ME sometimes gets terribly slow. Meaning there's a delay of a second or more on every action I do, whether that's clicking something, dragging the map or moving/rotating an object. This makes it basically unusable. The buttons are still fine though, as is the treeview on the left. It's almost as if the ME suddenly decides to use my on-board GPU, except that Task Manager shows that it's still on dedicated.

 

It may work for hours on end without failing, and the next time I start it up it's suddenly stopped working. Once it's slow nothing will fix it, not even restarting the ME, until I completely reboot my PC. I haven't really found any direct cause, except that resuming my system from sleep or hibernate seems to make it more likely.

 

Does anyone know what's going on, or even better, how to fix it?

Haven't experienced that, but i always use the scaling manifest trick since the ME on my Win LTSC and a 4k monitor does not crash anymore (almost).

Especially dragging items and on saving my ME likes to crash if i don't use it.

Two factors which are always difficult to check is windows (that friggin' windows update) and GPU drivers. SFC.exe?

[DN308]

I agree with that. I experience this slow response from the last update too 

[Jaegermeister]

I have not noticed any change

So it's confirmed. It must be windows related then; would be interesting to know which versions you guys have installed.

BTW i find the game loading time about 10-20% longer since 4.602.

[DN308]

I don’t know which W10 I have now.

 

Considering the time to load missions, I can’t really have an opinion since I changed all my configuration few weeks ago. And now, I have a totally different experience. Missions load something like 5 times quicker than before with a brand new CPU, ram and motherboard.

 I can’t be a good sample for that.

 

it’s just that since the last game’s update, the ME loads the viewport with a little delay.

I have Windows 10 Professional Build 21H1, and have noticed no change in editor speed of reaction, and I use very heavy mission files which are over 6 MB for MSBIN and around 10 MB for MISSION files.

Huh how do you come to that conclusion? I think DN308 and I were talking about game updates, not Windows updates. At least I was.

 

That doesn't mean that it must be game-related either, not at all, but so far I don't see any indications either way.

 

Anyhow, I'm running an up-to-date Win10 20H2, with an up-to-date RTX2060 video card (not sure which driver version, but it's the latest one).

[DN308]

I do too (game update)

[jollyjack]

well since you both experience the same issue, so it's probably not hardware/driver related?

PS what type of monitors do you have; i experienced problems with my 4k acer.

A DirectX check? NVIDIA driver version?

[DN308]

That’s a LG 4k

[jollyjack]

Well, i used the manifest trick for about 5 months now, for my 4k 144 monitor. However some seem to do fine without it ... i think?  

At least i found after a lot of experimenting that this solved my (mostly crashes on zooming and saving) ME problems.

Come to think of it, i installed NVIDIA's latest (4.71.11) without experience. I think i had a graphics issue with the older version.

Stop using the treeview and your experience will be much better.

No I'm not talking about the treeview updating for a few seconds when adding an object. I'm aware of that problem and it's very easily mitigated by properly using groups, which I tend to do anyway.

The issue with treeview when you have many groups and subgroups happens when you load a group but at top level. If you set a working group down the tree and insert a small group or an object it is immediate.

 

I have around 25 groups at top level (under the editor mission group), the number vary with the missions. You can also group them inside one main group but if you do so you loose the possibility to select them directly on the treeview which is a limitation of the editor and you need to go through the object selection window which is in this case not very practical. You have to find the right balance.

 

Each of these main groups have multiple levels and tens of groups in total. When in a very large mission file your treeview is open and you add a major group then it may take ages, easily up to a few minutes.

 

But if you close your treeview and have only one line which is the top editor mission file group, then it is much much faster and may take about less than 10 seconds.

The PC performance may play a role also.

Well, thanks for your help, but as I say in the post you quoted, my problem is *not* the treeview-related delay when adding/deleting an object.

 

It's viewport related. Like, my FPS drops to 1. So if I drag the viewport, I see the result only a second or so later. If I move an object, likewise. If I click something, likewise.

 

Anyway, after experiencing the problem for several weeks, I haven't seen it since a week ago or so. Fingers crossed it stays that way.

[=KG76=flyus747]

yeah i have this problem too.

 

every few months, the editor will return to normal and function as if nothing is wrong and then quickly revert back to this 1 fps state.

 

makes using the editor a not enjoyable experience

[IckyATLAS]

I have not encountered that slowing down problem at all. Maybe if you have some background tasks that take a lot of CPU resources, then the editor may slow down as he does not have enough CPU power available. When working with the editor I have no other stuff running except the usual windows stuff, antivirus and mail system.

[jollyjack]

It's always hard to say when you don't know the hardware situation. f.i. a laptop with an external USB drive has probably more issues like this than a special game PC

[AEthelraedUnraed]

It's not a CPU/GPU/RAM issue, at least not in my case.

 

As I said in my OP, it usually works completely fine. But it might start to get slow suddenly and without a warning, and once that happens, it remains slow until I do a full system reboot.

 

Having started the PC from sleep or hibernation increases the likelihood that the editor gets slow, even if IL2 wasn't running at that time. There are no other programs that show this issue.

That sounds like its related to Windows' standby list.

 

Have a shot at clearing it with RamMap when it next occurs and see if speed is restored without rebooting:

Thanks, will try and report back.
