FPS crash when using FLIR

[markturner1960]

I have a new issue whereby when I switch to using the FLIR, my FPS crash. I am running external mfd screens from cubesim, but have had these running perfectly with no performance issues for months now.....it is 100% tied to the export of the mfd screens, as if I dont use them, in the sim, it does not happen. However it only happens if I use the FLIR, all other screens in radar and moving map, it all works fine......

 

any ideas please?

Which jet?

[markturner1960]

hornet and harrier....

Is there no one from ED who can comment on this and likely cause? Its extremely frustrating to have invested in peripherals and to spend ages getting them set up and getting them working properly for a couple of months only to have them suddenly hit with an issue that makes them un useable......It must be a DCS issue somewhere, as this only started happening after the last update and is plainly tied in some way to to the export of data to the MFD screens via the lua files? 

 

Thanks....

Hi Mark. If you want your issue investigated, you need to provide at least a dcs.log file showing the crash.

If i happens in a particular mission, you also need to attach a track.

[markturner1960]

Hi Flappie thanks, its not mission specific, here some files that may hopefully throw some light

FPS.trk DCS-BIOS.log dcs.log Export.lua

 

do these all need to from right after when it happened? as some of them are not, as I am running without the screens while I try and resolve this...

The log files are of better help when they show the actual crash, yes.

So far, I can only tell you you're having an error with your DCS-BIOS scripts (it happens 29 times in 40 minutes) :

 

2020-12-04 20:51:27.145 ERROR   Lua::Config: Call error LuaExportAfterNextFrame:[string "C:\Users\Mark Gun House\AppData\Roaming\DCS-BIOS\Plugins\module-commondata\CommonData.lua"]:26: attempt to index local 'selfData' (a nil value)

It seems you need to update DCS-BIOS. Backup your DCS-BIOS configuration files and install the latest version of DCS-BIOS.

 

By the way, your track doesn't show a AV-8B, but a tanker.

[markturner1960]

OK, HERE IS THE SAME FILES RIGHT AFTER A SMALL FLIGHT SHOWING THE ISSUE. CAN YOU ( ooops, sorry for the caps....) see a FRAPS overlay when replaying a track? if not, as soon as i select FLIR, FPS goes from 115 or so to 15. and goes back up when I turn it off.

Export.lua dcs.log DCS-BIOS.log FPS2.trk

 

went to the linked post but did not really understand the content....

 

do I need to uninstall DSBios first? and where are the saved config files? sorry, new to this stuff....

I was assuming you knew DCS-BIOS better than me, since I've never installed it. I have no clue which files you need to backup. Have you ever customized it?

The DCS tracks don't record your video output.they only record what happens in the game. It means I will not be able to see your FRAPS overlay.

 

I tried reproducing your issue but I don't own the Hornet: I'm unable to see the FLIR screen. Can you please make a new track using the AV-8B? I own this one. Then I will be able to tell you if I also get low FPS or not.

[markturner1960]

Hi Flappie,  will do,  although, how does you viewing my track make your system duplicate the issue? Is the track not a simple recording? I know enough of DCS bios to 9nstall it to get my Tekcreations UFC working as per the instructions!!

 

I don’t think you can reproduce the issue as a bug, I think it’s something specific to my machine and set up otherwise loads of people would be complaining. And as I said, it’s only a problem when I use my extra screens and the custom .lua file. If I just use my normal monitor ,no problems. To reproduce, you would also need to have the extra screens etc.....

[Flappie]

You're right. And I have only one monitor.

Try updating DCS-BIOS and see if it's any better. Simply run the latest installer.

[markturner1960]

Done, no difference, issue still present....do the logs etc tell nothing?

[Flappie]

Not that I see. The only way that I know of to "see" stutters through the log are lines showing the sound couldn't be rendered because the CPU was too busy, but you don't seem to have those.

 

If you keep having the error above in your dcs.log, you should try reinstalling the "module-commondata" plugin.

See, your log error deals with a 'v' function at line 26. In the latest version of this plugin's "CommonData.lua" file, there's nothing at line 26.

[markturner1960]

Ok, thanks, how should I do that , run a repair?

[Flappie]

See the official DCS-BIOS documentation here.

 

It says to launch the "DCS-BIOS Hub" app, then check all of your installed (green) plugins boxes, and then click the "Apply # available updates" button.

[markturner1960]

ok, I un installed dcs bios, and still have the issue, so can say its probably not to do with that?

[Flappie]

OK for DCS-BIOS.

I see you have the WinWing script loaded in your Export.lua. Try commenting it, then see if FLIR still hurts your FPS.

 

Comment the 2 first lines of your Export.lua:

--local wwtlfs=require('lfs')
--dofile(wwtlfs.writedir()..'Scripts/wwt/wwtExport.lua')

 

Then add this line for SimShaker, at line 3:

local lfs=require('lfs')

 

I'm taking this post as an example. It was about WinWing eating CPU cycles.

Some more info about WinWing and the Export.lua file:

Hi Flappie, the latest update has changed things. While it has essentially started behaving as it should do, and despite the frame rate counter saying differently, there are still delays and some stutter in the feed to the MFD, IE scrolling using the TDC is tricky as there is a delay in input .....also head tracking becomes quite in smooth. 
 

so the update has rectified the issue, but not completely. I would say from a bug tracking viewpoint, there is something still going on detrimental to performance when using the sim in these parameters.
 

I am going to check the .lua file as you indicated, thank you.

[Sydy]

Same happens to me. Any update?

[Flappie]

@Sydy, don't hesitate to notify users thanks to the forum's @nickname feature. Please attach your crashlog (most recent ZIP file in your "Saved Games\DCS...\Logs" folder).

 

@markturner1960How is your DCS-BIOS doing these days?
