DCS process is occasionally not shutting itself down after exit.

[MoleUK]

This has been happening for a few weeks if not a few months now intermittently. It wouldn't bother me except the process is still eating the CPU time (seems to peg itself at 12 ish%, which i'm guessing is 100% of 1 core as when the game is running it will stay pegged at 25% using two cores fully.

Managed to get a log after the last incident and get a few SS's. Launching in VR, using quit to desktop from in-game typically.

Try again without mods.

Been happening since before I installed either of the mods.

I am no log wizard but it always says DX11 backend error... When did you last upgrade your Nvidia driver ?

 

The only time when I encountered such things was when I tinkered with VMware or test-installs on physical machines with too little RAM, that often led to not shutting down properly.

If it rather seldomly happens with small missions but happens often after larger missions it could be RAM, though 32GB should kind of be enough to not fail but who knows.

It has been a couple months since I've updated nvidia drivers, so could give it a shot.

It's still happening. Not a huge issue as I've gotten in the habit of bringing up task-master after exiting to check if it's still running.

I did remove the mods for a while but that didn't change anything. I mostly fly MP on Enigmas, so I'd guess that mission is on the larger size.

Can you provide a log from that case?

Sure, as luck would had I just had one.

Hi. Please ensure Windows HAGS is disabled.

Dear Flappie,

I'm still having that issue. Technical support could not help with that too. HAGS had no effect on it. In fact in VR disabling HAGS puts extra scheduling load to CPU and negatively effects performance since DCS likes to overflow VRAM a lot. Technical support told me to set a gigantic page file which I did. Had no effect and I reported it back. 

Just wanted to chime in since I have seen my post is linked. I advise everyone checking task manager and manually killing DCS. It happens more than 50% of time with me. It now become a standard procedure for me for quitting DCS. 

Cheers,

HAGS is off. Re-sizeable BAR is on tho.

Yep, I have to check every time I quit DCS atm. Not a huge issue as i'm in the habit of bringing up task manager before launch every time as well to set DCS to high CPU priority.

Interesting you had a good experience with HAGS in VR tho, might have to try switching it on.

You running in VR on the Q2 as well?

Well it is not magic bullet. It does what it is designed to do, takes away vram scheduling from CPU so in a game like DCS it gives some more cpu headroom for you.

Most people fly dcs at high texture settings without having minimum 16GB vram and this puts huge load on memory operations since DCS uses incredibly high VRAM. When this happens in VR you get stable powerpoint level low FPS if HAGS is turned off. If it is turned on than you get stutters nervous framerates since VRAM overflow is huge. Both are unplayable

But in normal conditions I see little less cpu usage when HAGS is on and little overflows are handled better by a sutter than fps dip.

Yes I use Q2 also.

Thanks for your feedback. I'll ask for the Solved tag to be removed.

Are you using any software to boost your GPU? MSI Afterburner or something in the like?

Afterburner is installed on my system, but I typically close it when running DCS and no OC is being applied to my GPU currently.

Nope, I build computers since intel 286. I'm old school I keep everything barebone I use nothing: even no voice attack, no tac view, no virtual joystick no chrome no discord no srs nothing. I play single player. Only thing runs together with DCS is Oculus App since I only fly in VR and most of the time task manager GPU tab to check VRAM usage. 

I have seen this happening also in 2d when I run dcs without VR for mission editor only. But since it is very seldom I cannot tell how frequent this happens in 2d.

Thanks!
