Stuttering and long lock ups

[Manhorne]

Ever since they added this "Multi-threading" I have had nothing but problems and now with today's update they removed the ability to load DCS without multi threading. However, this new update is worse than the previous as it has made the game unplayable for me and I have spent hours today trying to get it to work and nothing works. I get constant stutters and long lock-ups. It is super annoying right now. Does anyone have any suggestions if they have had this issue?

best first step is uploading your dcs.log. it may have some clues.

I'm getting the same, extremely poor performance and stuttering all the sudden, nothing apparent in the log files. Sometimes the game stops recording joystick input during a heavy stutter even though background monitor shows them still giving output. Replugging them in fixes the control loss, but it keeps happening mid flight and the stuttering is atrocious.

I just updated mine and still have the single threaded .exe in the bin folder.  The MT version is unplayable for me due to microstutters even after following all the advice I could find on this board.  Single thread works perfectly as always but means I can't use DLSS.

ST is awful for me, 35 fps, and this is much lower than ST normally is. MT instead is 165 fps (249 theoretical)

I used process lasso to disable SMT (hyperthreading for Intel) and it seems to have helped cut the stutters for now, but I may need to put in a few hours of flight to be sure.

Well I was finally able to get the non-MT to load. I have no idea why it would not yesterday when I tried. It was like it had been removed . I have tried to get the MT version to work but for me is very buggy . The non MT I have no issues with right now. One day when I have some time I will play with it and see if I can get it sorted out but its not an issue for me right now.

One cool tip for each update, so you can launch DCS straight in so you won't lose time closing dcs to open it from the bin-mt folder.

Do the following:

Browse your game folder ( not saved games).

"C:\Users\YOUR NAME HERE\DCS World OpenBeta\bin"

Move the file : "DCS_updater.exe" to

"C:\Users\YOUR NAME HERE\DCS World OpenBeta\bin-mt"

Make and send both shortcuts to your desktop/taskbar/start menu from these files:

DCS_updater.exe and DCS.exe

Enjoy.

This will prevent you opening dcs.exe from bin once you update it, and you will start from the bin-mt.

The performance is bad in DCS-2.9 . Vram maxed out and the memory leaks . My system uses 29.GB of memory for Syria map and 16.GB of Vram used Syria map .

The performance is no where near as good as 2.8 .

2.9 imho is a disaster MT is broke . Yea it all looks nice on YouTube videos but in real life NASA computers struggle because of bad code and now VR uses cant see targets because of the bad light and shading yea And nothing gets fixed .

well I am not seeming to have many issues, works pretty decent here. I guess some improvements would be helpfull but you have to make some adjustments.

 

Most problems in VR Stem from users trying to run max setttings with SS at 150% just not going to happen.. but I guess most users problems stems from that alone.. not all but some..

for me the stutters happens mainly in the UI and when I go external view or F10 map.
Launching a mission is a nightmare as my mouse and keyboard are unresponsive in the UI, ometimes for as long as 5 minutes
I can't alt tab, I can't click a button, the mouse is still on the desk but the mouse cursor in the UI is slighly drifting.

Once i'm in pit it usually works well unless I go external view or the F10 map, then it starts again and usually result in a crash.

Yesterday night a MP mission finished like that after 40 minutes of flying, (after a good fight in the Ui setup up the flight) I switch external view (F2) and it started to pause and freeze. I couldn't come back in the pit (F1) and remained frozen until it crashed. 

I don't get the issue all the times. It's not consistent

Well I have heard that while using the F10 map before you go back to F1 zoom back in on your position. something about it loading all the texturesandsuch when zoomed out and going back into F1 view..

I really don't think anyone is running 150% maxed out on DCS  VR . There are plenty and i mean plenty of clever people on discord saying VR is bad in DCS with 2.9 . And there is plenty of advice on other platforms says so . Yes you get the odd person coming in and struggling that have maxed out settings but most are new Too DCS VR .

As with the question and answers video by Waggs  , most questions were are you going to fix the performance . That was the main question .

I've been playing this game since Flanker . Been in Two high class online squadrons competitive online gameplay . I would not enter any compition with 2.9 DCS its so unstable . 

You cant see anything . See this photo that black dot looks ok , but in VR its massive blob and if i turn off this new spotting i cant even see targets .

Yet i can see quite well in other simulations  .

This sounds like VRAM is maxed out , if you keep switching to F10 map it loads memory , when you switch back to cockpit that memory stays in Vram .

Same if you switch from server too server memory loads and it does not get release when you swap , or it takes time to get released . I'm not sure . ? 

When I play online if I close DCS my memory is still running and it takes quite awhile to get released . This photo shows my memory after close down of DCS after 5 minutes . If anyone knows or see a problem please and a comment.

Well I seen it happen more then once. I been saying in VR if you cannot maintain your Hz in the FPS rate you will see stutter. I am able to keep above 60FPS as I only run 60hz and do not get much stutter. I play online as well and rarely get stutter. but I am not running 100% REz in the headset which allows me to maintain my plus Hz rate..

 

I been seeing some users catch on to this trick. in VR it is especially noticable when your FPS fall below the Hz rate..

It has nothing to do with the F10map. I have the issue just entering the UI from windows. even before I do anything. It's just painfully slow UI once I launch DCS
it can last 10 minutes and then go away and  come back 3 minutes later. It's basically impossible to navigate in DCS UI and certainly not launch a flight.

I actually can see the issue even before I am in the DCS UI because DCS takes 3 times more yime to load.
And if I am typing a forum message like now on a browser while DCS is loading or in the UI my keyborad responds every 3 seconds to a letter. the whole computer slows down

When the issue happens, my VRAM is far from being maxed out. I'm at 17-18% VRAM use and 10% CPU use.
DCS in the process is highlighted as using a lot of energy.

This has been happening for me usually after DCS updates for a couple starts then seemed to vanish until the next update.

But since last update where I installed Kola at the same time it doesn't go away it's besically everytime I launch DCS

I submitted a Ticket t ED last week and they stated "many bugs in MT". Use C:\prgram files\eagle dynamics\DCS world\Bin then use the EXE file.
