This has been a problem for a very long time, and it never gets sorted

Indeed.. there needs to be a solid fix..

Hi PEOPLE!

Sorry for the frightening amount of text, but total gold info here.

Long time has gone by since this topic was created. Many patches were introduced to the game.

So I got wondering how the situation performance-wise has changed in the DCS World for other players.

On my end, the DCS World as-of-date is kinda working okay.

But there is a serious issue, but also there is a fix to that ("more on that later").

So I play DCS World 1920x1080, no VR, 120 FPS cap (for stability, 60 fps provides a more prominent frame spikes (if they occur at some big FOV shift)), there is no SSAO, no SSLR, Motion Blur OFF (personal attitude towards Motion Blur is that in every game it only makes the picture loose it's sharpness at the cost of big performance hit - no go), Depth Of Field OFF (no need because the Visibility Range at High provides a beautiful sharp picture where at the same time you can't see the "end of the world"), Preload Radius 60500 (I think that one can't see further than that, "ha?"), MSAA 4x.

I will post a Screenshot of my settings if some one is interested, so any one with a decent machine can improve performance-wise on the information above without losing the picture quality, but even improving on the quality, because "EVERYTHING EXTREME" is not the quality-best option, not only that but it is PC-RESOURCE-UNWISE (big time, total energy waste, big minus here, because of the struggle in the world with the energy).

Now the issue I am constantly encountering with the current DCS World is that at the first launch, after any mission start, I get these big freezes as if the game is trying to process itself, totally unplayable.

THE FIX IS: launch DCS World, load a mission you want to play, after start move FOV inside the cockpit, let it lag some, switch to Orbit Camera, move the FOV, let it lag some more, after that "Quit To Desktop" the DCS World, and launch the DCS World again, load the same mission, and you should have no lags, as if the game has processed everything needed at the first launch. Hope that this will help even one player, already would be a big win.

The issue I encounter always, each time I launch DCS World. Also, if you have Steam running, it is better to exit Steam ("just in case"), more resource availability.

It seems that the root of the problem lies in the poor optimization of the processing of the resource-demanding information, as if there is no streamlining, everything is getting thrown at the CPU at the same time. And don't you dare to go "try MT" on me, HUGE FAILURE ON THE MT, there must be ONE SAME GAME FOR EACH PLAYER.

DCS World would be the ultimate flight simulator if the serious problems of poor optimization would be finally addressed by the most respected Eagle Dynamics team.

And those reports or rumors that the DCS World lags only on the special systems is a total fail. The game behaves like that because it is coded in a certain way.

SO HUGE RESPECT TO THE DCS WORLD COMMUNITY

And now I want to know about you guys!

How are you running the DCS World? I mean how did you get yourself the YOUR-SUITABLE-OPTIMIZATION of the game?

Please, answer honestly, describe each annoying issue that kills your immersion in to the game.

Maybe SOMEONE will take note and finally will begin working on the FIXING THE ISSUE.

Maybe we can learn from one another.

Thank you for your attention.

The picture itself...

By the way, Afghanistan = no trees = no lags. Hmm...

you most likely have a bottleneck somewhere. 

If you want help please attach your dcs log and dxdiag

thank you

Came across a possible way to increase performance of the DCS World.

Maybe some one still doesn't know about this.

The possibility to increase the DCS World performance by adding the DCS World related files to the Windows Defender exclusion:

Windows 10 -> Settings -> Update & Security -> Windows Security -> Open Windows Security -> Virus & Threat Protection -> 

-> Manage Settings (Under the Virus & Threat Protection Settings) -> Exclusions -> Add An Exclusion

Add two Folders to the exclusions:

C:\Games\DCS World

C:\Users\YOUR-NAME-HERE\Saved Games\DCS

Add two Processes to the exclusions:

C:\Games\DCS World\bin\DCS.exe

C:\Games\DCS World\bin-mt\DCS.exe

This might help, but might not...

And don't forget to turn off Steam while playing the DCS World.

By the way, the notorious FPS Spikes still do occur, additional observation suggests that:

1. The FPS Spikes occur when there is some change in the CPU work while processing the game.

In detail: the FPS Spikes occur when CPU Bound (Rendering Thread) is replaced by CPU Bound (FPS Limit), and vice versa. When the swap occurs there is a greater chance for the FPS Spike to be triggered.

The FPS Spike - a moment in time, when resources that are being processed by one instrument (CPU Bound (Rendering Thread)), are getting send for processing to another instrument (CPU Bound (FPS Limit)).

The time it takes for the swap of the processing instruments is the FPS Spike.

2. The phenomena that causes the most FPS Spikes is the drastic FOV change.

Personally, in addition to he Cockpit Camera, I take advantage of the Orbit Camera, Fly-By Camera and Object Local Camera (configured as a static Chase Cemera).

The resources that need rendering inside the FOV constantly change, and this causes the FPS Spikes.

Maybe this is the case why some other players do not experience the FPS Spikes, because their FOV is confined within a cockpit.

Performance is very system and setting specific. There can be many reasons for seeing spikes, stutters or low fps. 

Usually its one or a few of these common reasons. 

CPU bottleneck
GPU bottleneck
Low RAM small pagefile
slow disk speed
problems with user scripts 
settings to high for machine
input issues ( disable hot plug )
antivirus creating problems
HAG setting in windows
Game mode setting in windows
bad over clocking
Parked cores creating problems

Through some miracle I came across something that might help those in need...

It appears that the Microsoft Windows (10) hides from the user a very important system processor settings.

The settings in question are:

1. Processor performance core parking min cores

2. Processor performance core parking min. cores for Processor power efficiency Class 1

Both settings must have 100% value set.

By default they are hidden from the user in the Processor Power Management in the Power Options.

The way to get to alter those settings is to download and install a third party software named ParkControl.

ParkControl - CPU Parking and Frequency Scaling

Inside the software you need to set the Performance (P) Cores to 100%.

Also, you need to set the Efficiency (E) Cores to 100%.

The original Author Of The Solution is BJ55.

His message: "In Settings disable "start at login", once configured there's no need to run the program in background".

Thank you very much.

This third party software appears to be something that is downloaded along with the next DCS World update. I mean the software is basically essential for some people to enjoy the DCS World.

Can someone check this?

Sorry but this third party software can not be packaged with DCS, there are many cpu's out there and DCS will work great with many of them, but the main problem you are having is windows 10 does not handle the cpu cores as well as windows 11 does. It can be very CPU dependant. 

thank you 

[FierceLV]

To be honest, ParkControl helped the entire PC performance.

Thank you very much.
