FPS drops from export scripts

[ianick]

Hi

Title says it all and in the link for video attached you will see on the upper right that GPU activity is just linked to APU start

It is nice that the GPU is triggered by the APU switch of the AH64 however not the main purpose of it, i suppose

Could you share the track-file or the mission-file please? We could test this behaviour on our own system then and provide feedback.

Thx.

No issue here on my end (tested on OpenBeta 2.9.0.47168 with MT in non-VR).

The mission is quite heavy (43 GB RAM was used) and I had some major short dips (1-2 seconds drops) when some scripts were loaded within the mission the first minute - but nothing too serious.

Startup worked fine with the Apache here (tested blue coalition Adana).

If the Apache startup works fine for you in an empty mission, I suppose there is a coincidence with your heavy mission and your PC setup.

it s a multiplayer mission

As far as i know i am the only one to experience that issue

how a script or action can decrease the gpu usage o0

Hi @ianick

I too cannot reproduce the alleged frame drop from your track or on my own empty mission. 

I suggest you run a simple repair on your DCS. Also make sure you remove mods temporarily if you have then, just for troubleshooting.

Thanks. 

[ianick]

I have done a cleaning and repair but no change (even a windows reinstallation)

[Floyd1212]

This also happens to you in a single-player quick start mission, on all maps?

What about a hot start and you shut down the engines and bring them back up again?

[ianick]

not in SP only on certain servers on MP

For example it does not happen to me on Tempest's server but on other few servers

 

[ianick]

ok i ve done few tests, it s happening in SP as well :

• when the mission starts with warn engine it s bugged, and when i decrease the power throttle the GPU is back to work normally
• so i stopped completly (GPU at 98-100%) and started the APU again, when the power of the APU rise enough to enlight the screen, the GPU activity fell to 60-50%

repair and mods removing done but no change

I ve also tested affinity core thing (good advices m8) , no success

but after a lot a tests it appeared it is the off/on RWR switch when it s starting and going from "bit/sys pass" to "active"

It s tricky because in the video above i thought in first intention it was when i switched the APU on, in fact it was when the RWR finished starting

it s mad thing:/

any idea, anyone?

-- load the DCS ExportScript for DAC and Ikarus
dofile(lfs.writedir()..[[Scripts\DCS-ExportScript\ExportScript.lua]])
-- load the DCS ExportScript for DAC and Ikarus
dofile(lfs.writedir()..[[Scripts\DCS-ExportScript\ExportScript.lua]])

pcall(function() local dcsSr=require('lfs');dofile(dcsSr.writedir()..[[Mods\Services\DCS-SRS\Scripts\DCS-SimpleRadioStandalone.lua]]); end,nil)

 

 

this export.lua file is causing the <profanity>

when i delete it everything back to normal but streamdeck & srs does not workin anymore

please advise

Same issue here.. I have 4090, 5800X3D, 64 GB ram. when i crack the einges it does that. I also have Streamdeck

Disable these lines from the apache lua file in the exportmodule folder.

The issue was resolved for me.

 

Just put -- infront of each line

 

if LoIsObjectExportAllowed() then -- returns true if world objects data is available
    if LoIsOwnshipExportAllowed() then -- returns true if ownship data is available
  ExportScript.LoAircraftInfo(mainPanelDevice) -- Provides a lot of aircraft properties
  ExportScript.AirportInfo(mainPanelDevice) -- Provides info on the two closest airports
  ExportScript.WindsAloft(mainPanelDevice) -- Gets winds at the aircraft
  ExportScript.GroundRadar(mainPanelDevice) -- Reports 2 closest friendlies and 2 enemies (Use in Single Player)
  ExportScript.AirRadar(mainPanelDevice) -- Reports 2 closest friendlies and 2 enemies (Use in Single Player)
  ExportScript.IglaHunter(mainPanelDevice) -- Locates closest Igla (Use in Single Player)

Thanks Ian.

I wonder why they exported all that data.

Removing it quite enhances the performance, specially giving a better overall stability.

You can get this, and a corrected F-15E (they changed the index of the UFC export) on my fork.

I found out today that the Apache on some servers (particularly I tried it in Contention and GF Syria) I have a stable 120 fps but when I turn on the CMWS a few seconds later my performance drops to the floor, with many stutters, lag spikes and drops in fps.

SOLVED!! Stream Deck Export Scripts is causing this.. once I disabled the line everything is working fine.

So You confirm my colleague observations who also was using the Steam Deck and had to stop it to be able to fly the Apache.
