FPS huge drop after hour of multiplayer

[camsr]

Testing my configuration, I had the FPS counter open my entire flight, and noticed a steady decline in FPS anywhere in the map after an hour.

It was attributed to Scene: Parse and it was peaking around 35ms.

I don't know what that is and searching the forum had nothing to say about it. My only guess is it relates to track recording, which also seems to be hardcoded into the game and is impossible to disable.

I am going to take one last approach on fooling the game to not record tracks, I think it's possible if I disable write access to the Tracks/Multiplayer folder.

Disabling read access prevented the game from booting.

Please stop coding LUA and make your game work.

Did you upgrade to 126 or fresh install?

[camsr]

The problem is assuredly the game, not the install. :thumbup:

I have the same issue, up until 1.26 I had no issues and could play multiplayer for hours, since this patch I go from 50fps to about 4 fps on or about the hour of playing mark making the game impossible to play. Stop multiplayer and restart and fps is good again until the hour comes up...

 

Please find a resolve for this issue as it is making the game unplayable in multiplayer...

 

My specs:

 

MoBo: AsRock 990FX Extreme

CPU: AMD 4170 (4.2GHz Quad)

RAM: 8Gb Corsair DDR3 1600MHz

GPU: AMD 280X Toxic (3Gb)

Game installed on Samsung 1Tb HDD 64Mb Cache

 

Game settings are all on High but have reduced them to Med but with the same issue, this is not system related but software as everything was good before the last big patch.

What module are you flying when you see this issue?

I wonder if AMD is having a DX9 Memory Leak.. Doubt it, but it's possible.

 

Also, I play for upwards of 4 hours at a shot online with no problems what-so-ever on Eno's.

 

Check you RAM/Pagefile usage and track it, when the page file fills up, Windows starts expanding it,

Which pretty much kills the performance of anything running until the Page file maintenance is complete.

What aircraft do you typically fly Skate?

I don't think this problem is isolated to AMD GPUs. Atleast one of my squad mates disconnects and rejoins after flying for a while, with an Nvidia GPU, due to performance degradation.

I had this problem while playing last week. Think it was a bit more than an hour though. I am using steam for updates though. Was playing the weapons training mission. Only me and a friend and I was hosting the server too.

 

Specs are in my signature. I alt tabbed out when I noticed the fps drop. I was at about 5.7GB ram usage in total. Dont remember what the game was using.

 

Oh and we were both flying the A-10C

Flying the A-10C online the other night and the game froze when I switched to external view. Anyway, brought up Task Manager and noticed RAM usage for DCS was steadily increasing every second; I watched it go up to 3 gig before I quit the process.

Mainly A-10C,

 

But I have every module, and have flown them all for considerable amounts of time per session.

 

If it's happening on both AMD and nVidia then it's likely a Memory/Pagefile event.

 

Quitting out of DCS and rebooting it clears the Pagefile of the DCS Data being stored.

 

So if it was full, and trying to expand/clear data, quitting pretty much resolves that issue and Windows Carries on whatever it was doing.

 

Try to track Page file size and usuage for 3 hours of DCS Game play.

There is a known issue with hosting, but it may be different than what the people posting earlier are describing, I can play the F-15 campaign, the first mission, and will see a steady decrease in FPS, but memory usage stays the same. This has also been reported.

[BabylonCome]

Thanks for replies peeps...

 

Interestingly enough I was hosting a server as I usually do with my squadron. However, last week I set my laptop up with the basic free DCS in order for it to act as server leaving my main rig to act on its own. I haven't had a proper test doing it this way yet other than a quick one just to check if the laptop/desktop connection works on my router - which it did.

 

So I will set up a session and have a good fly around and see if the performance drops after a while.

 

We mainly fly A10c but have also noticed it with the Huey - on same training mission.

Ok, if it is the hosting issue, keep an eye on your memory usage, record it at the start and if you have issues, check your usage then.

I would host before(maybe 4 months ago) for about 8hours with no drop. Same mission too.

 

 

Maybe it has to do with us destroying things?

 

The drop occurred after maybe 1.5-2 hours after starting.

I am not sure the cause, I know they are looking into it, and they have a mission that causes the issue but dont know if they have narrowed it down to the cause yet, perhaps try a different mission. But I think we will have to wait for a fix.

Will do, thanks.

I've just flown nearly 2 hours using my laptop as the server and in the cockpit on my main rig. Took off, flow to Texaco (about 45 min flight), took on some fuel and headed back to base (on our training mission) with zero drop in FPS. So it seams for me it was running both server and client on the same system was the reason for performance drop.

 

I have put my settings all back up to high and will try again at some point in the next few days to see if all stays good.

[NineLine]

Cool, let us know how it goes.

Memory leak?
