[INVESTIGATING] High Ram Usage Again


NeMoGas

Recommended Posts

So after this latest update (2.5.2.19273) I am seeing very high ram usage again. Before we got the memory manager update I was seeing anywhere from 9 to 13+ gigs of usage from the DCS process in task manager. After the update with the memory manager I was amazed to see it as low as 3.5 gigs to about 5 gigs for the DCS process in task manager. Since that update I have been watching my usage like a hawk. Now however after this last update I again am seeing 9 to 13+ gigs.

 

So am I the only one seeing this behavior? My setting have not changed and this is in the same MP server running the same mission I always play on. In fact the mission designer has removed some units to make it run smoother and I still see this increase in memory usage.

I have not checked actual memory use, but when the "texture unloader" was introduced, flying the AV-8B became smooth.

But with the latest update(s), for both release and open beta version, it has started stuttering again.

 

So maybe the culprit indeed is that something has been reverted that shouldn´t.

After some tests, I found that the stuttering mostly occurs with the Razbam AV-8B. Other modules do not stutter very much and the sim runs rather smooth.

So I just played about 4 hours in a MP server again and still the ram usage creeps up until it is maxed out and causes the game to lock. I have been mostly flying the AV8 and the game is as smooth as MP gets up until it crashes.

 

When I first loaded in, the server was almost full. The memore usage was about 6 gigs. Over the course of about 4 hours it slowly crept up to 13+ gigs. To me this is the same behavior exhibited before we had the memory manager or whatever ED calls it, back when we had the "memory leak."

So every time this has happened I have had to kill the process with task manager. As you can imagine when your system reaches 15.9 gigs used of 15.9 gigs there is nothing else one can do. The PC takes 2 or 3 minutes after the crash to return to running smoothly. Unfortunately it seems to have not created a crash log for this instance.

So this is only with the Harrier? Or does it matter?

That I'm not sure of. I have been mostly flying the AV8 the last few weeks, occasionally switching into an Mi8 or CA. I guess next time I play I'll fly something else and watch the usage. However my fps is quite high most the time going from about 60 to 100.

Ok so I just got done with a 6 hour session only flying the A10C. The memory crept up to just over 12 gigs without a crash the whole 6 hours. Im not sure if the session had been longer if it would have gone higher but it did last quite a bit longer. Although the usage was still much higher than pre patch it was still acceptable. So it seems this may be an issue with the Harrier. With the Harrier after 3 or 4 hours the game would be using all available memory until crash. This was on a 40 player server that was full most of the time.

I had the Mi-8 running for 3hours+ on BlueFlag today, constant RAM usage of about 10.5GB and 21GB swap, rocksolid. Left the server shortly before it reloaded the mission.

So, yeah, no issue with the Mi-8 module. Seems to be as you say, module specific and not DCS in general. I dont own the Harrier so cannot test that one for now.

Ok it seems to be a Harrier issue for sure. Just played in an A10C for about 3 hours nice and smooth using about 8.5 to 9 gigs. Then I jumped into the Harrier and the usage jumped to 12 gigs with very noticeable stutter. Same airfield, same server, same session.

 

If a mod could move this to the Harrier side of the forum that would be great.

Thats also my experience.

 

 

I can fly all other modules with quite smooth performance, but with the AV-8B I get some heavy stutters and often also freezes.

This happens especially when the DMT is displayed.

 

 

Right after EA release I remember there was an issue with all displays being rendered in the background even if not displayed - maybe this is back again.

With latest update I still see excessive RAM usage and stutters with the AV-8B.

Especially o the Persian Gulf map, it stutters alot.

 

 

I hope they soon start to optimise the module for better performance.

same for me, i have 32gigs ram . looks like to be altitude related, completly smooth over Dubai till descending near the ground, happened at Dubai and Dhafra others to test,

i do not get a complete freeze, just 1-2sec freezes, if i can recover it gets fluent as normal again.

 

what can this behaviour make happen.

is this already reported or analyzed?

av8 is completly unusable in combat situations at PG, so a lot are staying away from PG mission server because of that.

 

can a moderator please confirm that this is reported?!

The RAZBAM team needs to confirm if its reported or being worked on.

i mentioned this 2 weeks ago, i do get freezes and stutters when descending towards ground targets in PG, if i manage to climb again those freezes disapear.

 

log is attached,

memory usage was about 23GB!!!!!! the rest of the 32GB were on standby too, so 100% used

 

WIN10,i7 4771,32GBRAM, SSD, 1080ti

 

when i last time reported this issue it was forwarded to RAZBAM, because of flying the AV8B,

please can a DEV have a look at?

mission length was 74mins

 

unfortunately the track file exceeds the forum MB limit so check the dropbox link

I had the same issue after I deactivated the Windows 10 pagefiles. Set it back to auto and I've never experienced such problems again. Maybe this helps...
