Winwing export eating cpu cycles

[VirusAM]

My flight panels from winwing arrived yesterday, so I started using the winwing export again.

I'm noticing the cpu/fps performance issue as well on my rig with the winwing lines in the export.lua, even when I remove VAICOMM and Simshaker. Has there been any progress done on this weird export.lua behaviour ?

 

I tried to set the update cycle to 0.05 (default is at 0.1)but nothing changes.

So probably there is something in their script that is wrote in a bad way

I flew a 1.5hr mission last night and saw that Simappro used less then .4% CPU! Where are you guys seeing high CPU usage?

SimAppPro is not what's eating our frame times away. It's the script that occurs within DCS to feed the data to simapppro.

To see if you're affected, first check your frame times and the lua usage with DCS frame counter, then go to \Saved Games\DCS.openbeta\Scripts\Export.lua and then comment out those two lines like so

 

-- local wwtlfs=require('lfs')

-- dofile(wwtlfs.writedir()..'Scripts/wwt/wwtExport.lua')

 

Then check your frame times again.

 

For a lot of users, especially in VR, the difference is huge. There's apparently something wrong with the way Winwing is syncing SimAppPro with DCS.

Can you use the panels without the export like the throttle?

 

Yes, but you lose the blinking landing gear lever. It's not a big deal though, given that DCS is almost unplayable in VR with their export anyway

My FPS stays the same (locked at 60fps) during the mission....I don't fly VR, just Trackir

Yeah that very different.

To my in 2d using their export the fps are locked at 64fps.

Without the fps are free to jump depending on the context.

In Vr it is just unplayable

[MustangSally]

So, those of you that are having the problem.....have you sent the info to Winwing??

[Harlikwin]

Thats fine by me. It blinks in VR for me either way. I literally don't care what it does on the desktop. I mean its cool if you are playing in a simpit or monitor, but its irrelevant in VR. All I use the various software to do is turn off all the blinkenlights.

Can confirm the FPS loss using the standard export here as well.

[Bullant]

Glad I am not the only one.

i7-10700k@5Ghz

2080

32Mb ram

"High" default settings

Reverb G2, in game PD 1.0, Steam SS 100%

With the WW exports included (and all other exports disabled) - CPU frametime - 28ms

With the WW exports removed - CPU frametime - 9ms!

Guys, I may have found a workaround....

For those with a Nvidia GPU...in the nvidia control panel set vsync to fast.

This way I don't have any fps loss...for now I tried only in 2d...later i will try using VR.

A new version of Simappro has dropped that resolves the excessive CPU usage

[lolwut845]

After testing on my rig, the new 1.4.34_beta version of simapppro is much better, but it's still impacting my framerate. Subjectively, it went from unplayable to okayish.

In-game fps counter shows a LUA cpu usage of 2-3% without winwing lines in export.lua, 40% with old simapppro version, 8-9% with 1.4.34_beta.

 

Sadly I'm achieving my best framerate without winwing's lines in export.lua and with simappro turned off. Please note that I am playing in VR on an old i7-4790k, so I'm heavily cpu bound.

[Bullant]

Newest version of simappro didn't help me, CPU frametimes still at 28+ vs 10 without the exports.

I have noticed the exact same issue with the Combat Ready Panel that I just received (first Winwings product that I have purchased) - even with the latest beta software, there is noticeable stuttering with the Winwings lines active in export.lua, while performance goes back to normal smooth when I remove them and don't run the SimApp Pro software.

 

I also found the software to be somewhat messy in terms of cleaning up leftover files and registry entries upon uninstall, and randomly just deciding not to run at times.  I am very meticulous about software I install on my latest sim computer, so this (along with the need to log in and be connected to the internet for certain functionality) puts me off using the software or even keeping it installed (despite its impressive configurability).

 

For now I am using the panel with no SimApp Pro software and removed the added lines in the export.lua - after spending 30+ years fighting with setups that run flight sims smoothly and finally getting there, I am not willing to give that back and go back to stutters.

 

[FZG_Immel]

same for me. the export lines drop my FPS from 100 to 65....

 

the sim app pro doesnt seem to create issue in itself though. its the export line for the button lights to sync that are the issue

[Flav]

same here, fps drops when Lua mod synchronization with DCS is up.

actually is the best way for me to play with LUA up, with ww t/o panel in 2D.

thx for tips

 

may be an investigation way for devs; to find the real issue?

I just got the last Winwing panel in, so I now have both the Takeoff and Combat. Do I like them, of course... I could not build a button box at that low of cost to do what these panels accomplish.

 

FPS report : I get an average of 15-20 FPS DROP with Winwing enabled in the background to turn on-off the push buttons, landing gear, etc.

 

So for now, I'm not using the Winwing software nor scripts to sync my panels. The update rate on the Winwing script should poll only every 30'th of a second or so?

Sir, I LOVE Your Work!

I noticed a big FPS drop a few days ago, and lucked upon it being Stream Deck lines in the export.lua. Then found this thread, read through it, tried your fix, and voila - silky smooth DCS again. Would never have tried this fix myself, so thank you kindly mate!

Can any of you that are having this issue, please email info@winwing.cn with all of your findings and what you have done to fault find.

[Noluck]

I can vouch for setting the Nvidia control panel setting, from Vsync = Off to Vsync = Fast fixes the Winwing script FPS issue on my system.

 

In fact, with Vsync set to Fast I see no FPS drops at all with my setup. With it off is a big FPS hit with the script.

 

I still have an issue why I have to have the Winwing app running in the background to make it work. Also, you can't hit the minimize button on the top right, it will exit the app. Winwing has some work to do.

I hit the minimise button and it works fine!

Hi Noluck,

1.Could you please do a test ?Do nothing in Nvidia control panel setting.just cancel the vsync in DCS World setting.

 

2.you can hit the minimize button ,just expand the  hide icons on the taskbar.you can see the simapppro icon.Then double hit the icon,you can open the simapppro again.

1) I do not have any vsync set or enabled in DCS. I only have the fast vsync setting in Nvidia.

2) Simapppro is working fine minimized, my bad.

Thank you for your reply.

 

Could you please refer the attach file to disable the vsync in DCS setting And set the vsync in Nvidia to the original status?I need to know if only disable the vsync in DCS Setting have the same result.

 

Regards
