[REPORTED]Multiple Users, Multiple Bowwave crashes.

So we tried to run a mission tonight we had 12 people on about 2/3rds of our users were in VR, and every one of us in VR had the dreaded Bow-wave crash that has now been plaguing the game since 2.5.6 dropped. Every one of us has good rigs, ranging from 2070's - 2080ti's and RX5700xt's etc with 16-32+ gig of ram etc. Some times the game will run for hours with out any issues, other times you will get the crash the moment you select a slot. Something that was done with 2.5.6's renderer is at fault the memory space in the logs looks exactly the same each and every time.

What is interesting however is that it seems to be tied to something very very specific though we can not actually work out what the trigger is (unit/static or what) as we have a practice mission that runs 100% fine for every one in VR for well hours. The other note is that all of these machines can run DCS with out any other issues. I've included a copy of a mission that has the issue happen eventually and a copy of a mission that doesn't. Along with all the logs from the users from TGW whom were around whom could send me them after (most had left to sleep out of frustration from this crash)

What we do know is there is no commonality beyond 'all using vr' we have people crashing on a mix of systems and a mix of headsets from the Rift S - the Reverb.

This is killing the game for our group.

Thanks

One drive Link of logs etc from tonight: https://1drv.ms/u/s!AowS0PfqL_UIp2QaF-Q_BYDlrRs5?e=XSy3IV

Prac2 - can be run for hours with out any issues.

Red Dawn e4 has crashes happen.

- Including logs from 3 separate machines 1 of which has debug logs in.

- server log including debug log as well incase it helps at all in trouble shooting.

Regarding this crash that appeared multiple places in the forum, all of the people of my wing having it in MP are muds and choppers.

We think it could be related with this file

\Eagle Dynamics\DCS World\Config\Effects\ParticleSystem2\vehicleTrail.lua

This one appeared in the 02/20 OB update and that's where the crashes related to bowwave appeared. shipTrail is using it too, but is present in stable, not causing any crashes.

I advised you test by either :

-removing the file (keeping a backup somewhere if removing it crashes the game even worse)

-in the SAVED GAMES\DCS\Config\options.lua, set ["effects"]=3 to 0 to try disable effects if this is a valid option.Not sure it'll accept 0.... It won't be pretty but might eventually solve it.

I haven't any one yet on my side testing it as they all moved to stable, and didn't encountered the crash myself so can't be sure. I should test in MP as it apparently doesn't occure in solo...

If you wish to have a try and can report success/failure that would be nice !

Thanks.

one of my guys tried it and reported an hour with out any issues, I'm gonna give it a shot next day or so. See how it goes, it might not even be the whole file looking at the lua but possibly just one of the items in there.. I'd almost point at

{
	Type = "vehicleBow",
	SubEmittersOffsets = {
		{0.0, -1.0, 0.8},
		{0.0, -1.0, -0.8},
		{0.0, -1.0, 0.0},
		{0.0, -1.0, 0.4},
		{0.0, -1.0, -0.4}
	},
	Texture = "foam2.png",
	TextureFoam = "foam_03.dds",
	ParticlesLimit = 150,	

	ScaleBase = 0.35,
	ScaleMax = 0.5,
	OpacityBase = 1.0,
	BaseColor = {1, 1, 1},

	SpawnSystem = {
		RepeatSpawning = true
	},
	
	Speed = {
		{0, 0.1},	
		{50, 7.0},
	},

	LifeTime = {
		{0, 0.0},
		{20, 1.7},
		{50, 2.0},
	}
}

given it's the only one with transperancy apparently and it's a render crash in transperancy that seems to be the actual cause. Course would be nice if Eagle Dynamics could confirm if they have found the cause and FIXED it or not for next patch as well.. But if we can work around it it's a start right?

So even with that file renamed to .bak so it doesn't load in.. still get

Extra one to add to this @BigNewy we have one person whom had the crash with out being in VR and yet the metrics look almost the exact same.

file is attached.

I'm just collating from my guys now.. know there is a patch coming tomorrow.

dcs.log-20200415-135631.zip

I just got it. Typical stuff in the log. I noted that this is the second time I have noticed that the crash happened after i got in a jet for the second time in the session.

Same issue here, clients connected to server not running in VR had no problem.

I have uploaded logs on a different post here for this issue: https://forums.eagle.ru/showpost.php?p=4334256&postcount=15

Same error here, with VR.
