DCS shutdown time

[Trebor18320]

Why does DCS take just as long to shutdown as it does to startup??  It wouldn't be an issue if it didn't Hijack the monitor with a backscreen during the shutdown process!  I don't actually care why it does it.. I just want it fixed so it does not.

Agreed! 
This has been happening since Multithreaded implementation. Single Threaded didn't had this issue, only on DCS MT executable.

2 monitors here. Second monitor responds normally. I can open a browser window meanwhile DCS is "shutting down" and there is not much CPU and Storage activity when this happen. 64gb Ram here.

It would be nice if it behaved like ST did when closing DCS.

The black screen only appears in 2D, in VR it's not there.
Also, if you bring up the ingame FPS counter (and game data) and leave it active while exiting, it's still displayed as long as the black screen is visible.

For the multithreading model, all threads must join back to the main process in order to terminate them for the graceful program exit.

Valid point!

Than why does it die faster and just as graceful with the task manager, dead is dead.

Is that a serious question? Brute force is always quicker.  And it doesn't die more gracefully when you kill it. IT DIES! 

What @scommander2 says makes sense. Let's say there's a process that needs to write something, like in the log file or whatever. And it doesn't run in the main thread, then the main thread needs to wait until said thread is done.

Ever been shopping with your wife, your kids or whatever? You can't leave until they're done, right? (Especially the wife). Now, you can brute force it, but I'll imagine there will be spilled coffee, ice cream and tears or worse, all over the place.

That said, I'm sure ED finds a way to stream line this. And also said. I didn't have this issue when I last played DCS in January. Maybe once or twice before last Christmas. Don't remember. And I don't know what would happen in my computer today. Point is, ED needs to find a solution that works across all different kinds of setups. 

Cheers!

Okay, please don't my words as it. 

Let's monitor DCS.exe from the task manager in the "details" view and make the column "Thread" visible.

Assuming that DCS.exe shows in the "details" view and watching its thread count while shutting down DCS...

The thread count will decrease to 1 and the program exits.

Hope it helps.

I seriously have problems with this DCS MT thing .... DCS starts and closes very slow, and i used all sorts of repairs and refreshing procedures. NaDa.

Also in the ME i cannot delete a once installed plane, the delete function only works for added waypoints.

And why do i get that NVDIA splash screen, i dont have an NVIDIA RTX any more and deleted all their drivers with the DDU uninstaller. have an AMD 9070 XT now BTW.

All off topic but let's do it:

1. There's no going back to DCS ST. You may have other problems, mods, slow disk or AV checking the files thouroughly. I suggest making a new thread with a log.

2. Use the red X on the left bar if Delete key won't work.

3. This is to inform that the game supports nVidia's DLSS. Nothing to do with your card.

Hi Draconus, thanks ... the red X works Super! PS i bypassed the AV for DCS, but i will check it again ..

Is anyone else finding extremely long waits to exit a mission, or worse, a sever?

When I want to exit a mission back to the Mission Editor, or change servers, there is a super-long wait before the transition happens.

It takes a single-player mission from 30-120 seconds to return to the ME, and for Multi-Player servers, it takes upward of 5 minutes to be able to disengage and leave the server.

This did not used to be the case.

Thinking it was mods, I disabled everything.  Well, except for Tacview.  But I've been running that for 6 years without issue.

Has anyone else encountered this?  I have DCS on a fast Samsung 990 Pro SSD, and I have 64GB DDR5 RAM, an i9-14900K CPU, and a Nvidia 4090 GPU ... so it really shouldn't be hardware resource constraints.

Disable HT in Bios. Fixed everything for me, long loading times, exit times - for missions and DCS, loading missions, saving missions, etc.. all the lag in the UI is gone. 

[SAM77]

Yeah, I had to disable HT in bios too. It worked fine with HT until I updated my bios with the latest one back in September. 

[HC_Official]

I just alt tab and kill it dcs.exe in task manager aint nobody got time for that

That's always a point of discussion. For some games they recommend it to be turned on, for some to be turned off.
That you have to go into the BIOS makes it even more problematic.

[jackd]

Well, disabling HT in BIOS certainly speeded up my DCS startup and exit.

Wonder why that's not implemented in the whole DCS system itself ...
