Instantly Boost DCS World 2.9 Performance With Process Lasso!

Link to Process Lasso: bitsum.com/
Hey guys! Today we have another awesome tip for upping your performance in DCS World, and most importantly the consistency of your performance in game!
Ever since upgrading my PC to an i9-14900K and RTX 4090 I have been extremely frustrated with DCS World’s performance and in particular the consistency of that performance which seemed to dip far below that of my old PC.
While excluding DCS World from antivirus did a lot to help the problem it did not solve it entirely and I was still seeing a lot of inconsistency, sometimes DCS Would perform amazingly and sometimes it would be a stuttery mess!
This led me down the rabbit hole of researching gaming performance with the Intel i9-14900K, which then led me to disabling my E-Cores or Efficiency Cores through my BIOs, and like magic, all of the performance issues DCS World was having were completely and totally solved in the blink of an eye.
However, like the Meme, we pay for whole runway we use whole runway, I pay for whole CPU I use Whole CPU, popped into my head and I wanted to find a way to not artificially limit my CPU and have less power for background actions I need running while flying in DCS, such as Nvidia Shadowplay, SRS, Chrome Tabs, etc, While keeping DCS off my E-Cores.
That's where Process Lasso comes in, an awesome little program that lets you easily and quickly, on the fly, ensure DCS is running on your P-Cores or Performance Cores!
So lets take a look at how we can set up Process Lasso to get the most out of DCS World, or any other game or application you may be using!

Hey guys! Here is a link to the Process Lasso Website: bitsum.com/ And a link to my video explaining how to Exclude DCS From Windows Defender Anti-Virus: kzbin.info/www/bejne/gKTLfYKumr1mmq8si=1klK8nhsp31FNKKQ

[@Specter0420]

Not sure if you mentioned it, but this applies to virtually ALL CPUs to one degree or another. Even disabling access to the hyperthreaded/SMT cores can have a benefit on older CPUs. The P and E cores aspect applies to Intel CPUs from 12th Gen on. On AMD you'll want to adjust if your CPU has multiple CCDs (5950x, 5900x, 7950x, 7900x, 7950x3D, 7900x3D, threadripper, etc.). Lock DCS to the cores of one CCD so the slow infinity fabric is not used. For the X3D CPUs, you want to lock DCS to the CCD with massive cache.

[@stopthemadness398]

not fully understanding why you are having problems with a high-end GPU and CPU???? two why would you make a video after you upgrade your computer????? so what about using a 3050 GPU and an i5 CPU ?? will this work ????... I bet you don't know... every person that has a high-end computer shit on us little guys by showing off what you going .. everybody doesn't have the money to buy a computer like yours .. so when you talking about a new program you should keep in mind us broke computer players

this really worked. thank you, because these stutters were driving me crazy. this also explains why these stutters come mainly in multi threading mode.

[@Daniel-jq4qk]

I really appreciate these performance videos lately Spuds, as I too have recently built a brand new PC which is a tremendous upgrade from last and that includes even the monitor as I came from a 1080p tv to a 1440p monitor and GTX970/R5 1400 to a Rx 7900XT/R7 7800x3d. I am still getting used to windows 11 and the video specifically talking about the Windows Security and how to boost performance helped tremendously! Now, just need to make the jump to VR next year, which may include another processor upgrade, possibly even another GPU upgrade lol. But, playing DCS with buttery smooth performance and actually being able to make large complex missions without my PC crashing is just an awesome experience..

[@MrNephilimBorn]

Thank @spudknocker for the tuning effort and analysis! I have analogous hardware and can also verify this makes a difference where MT stutters. My CPU priorities also include ovrserver (quest3 openxr runtime) & audiodg (seems to alleviate audio stutters that break immersion). I had also dedicated a CPU core to the audiodg runtime.

Thanks for another excellent video on optimization for DCS. My newly built DCS PC is quite similar to yours's 4090 GPU, but I 'm using AMD Ryzen 7 7800X3D CPU. Any thoughts on if this would work on the Ryzen CPU infrastructure?

[@Munky332]

Ryzen doesn't use E-cores, there's no need for this. If you had a 7900x3d or the 7950, there might be a reason to limit it to the CCD with the actual 3d cache, but the 7800x3d only has 1 CCD so its a non-issue.

[@wingnutnb]

Thanks again for another great video. Just wondering if I am doing something wrong, when I follow your instructions to the CPU Affinity Tab there is no PCORS BUTTON or ECORES button to push. I am running a I7 !0700K CPU and wondering if its architecture does not lend itself to the provisions of Process Lasso. Thanks

[@takeoffwithjakesoft]

Unless I'm mistaken, AMD users can ignore this. There is no e-core/p-core on AMD processors so all cores are the same performance AFAIK.

[@gabriel-bl4ckh4wk-6]

AMD users like me can only click on "Disable SMT" instead, it's the same thing, deactivate all your emulated cores, i learned this on a performance guide tutorial to Tarkov. But if the games now has compatibility with multi-threading (MT), idk if this is a good idea, i wonder.

[@Specter0420]

You're mistaken. Lock DCS to physical cores (non-SMT) if your CPU has more than 8 threads and you'll see a boost. If your AMD CPU has more than one CCD, lock DCS to the physical cores on one CCD so the slow infinity fabric isn't used. If you have a 7950x3D or 7900x3D you REALLY want to lock DCS to the first CCD, the one with massive cache.

[@takeoffwithjakesoft]

@@Specter0420 OK, good info. My performance with the 2.9 patch has been consistently butter smooth, but I'm on a Ryzen7 5800X. Regardless, the procedure as presented in this video can't be followed if you have an AMD CPU, you will see different options even if it accomplishes the same thing.

[@Daniel-jq4qk]

First, this app is similar to the app we used to use for FSX which would lock apps and games to using only specific number of cores which was awesome because back then and honestly even today most CPU's and Games utilize only about 4-6 cores at most but also the first 4 cores in AMD processors generally provide the most performance so it is nice to be able to lock a game to only certain cores. As for the comment about disabling your other CCD(s) because of Inifity Fabric, only certain games take a hit in performance because of it others can have a boost it really all depends on the game and it's optimization. I dunno about DCS but in general the performance hit is usually VERY little and performance reward for disabling it does not normally make it worth it if you are already doing extra background applications like streaming or video editing etc. But that's up to preference.

[@marc_svsengineering4319]

Eh, I have a thread ripper 16 cores. I tie everything I can on the 0-11 cores and save the last 4 cores for DCS. DCS only uses 2 cores, so I tied it to my last 2 cores 14-15, I run VR so SteamVR/SRS or any other programs related to DCS to 12-13. Haven't had any issues in the last few months while running it this way to include other programs I use (adobe/steam games/video editing).

[@mururoa7024]

If you have an AMD cpu you don't need this since every core is equivalent to a PCore, and you can set the DCS process to a higher priority directly in the Windows task manager.

[@harrysmith1986]

Thanks, Do you have to do this every time you boot up DCS??

[@SackyX]

I think you can do the same thing to the cpu via the bios but for anything that you run.

[@DickJohnson3434]

Do you have to run ProcessLasso in the background while playing DCS or can you just open ProcessLasso, change the settings, close it and never open it again?

[@michaela_B]

Thanks for this video. But I don't know what to do with this program? I can do that more easily by hand.

[@496kartoon]

Do you open this before launching DCS and run in background or is a set and forget?

[@ka-uy8yh]

process lasso will always run in the background, once you've done what the tutorial says you can completely forget about it, but kep in mind that it will give oyu a very annoying popup everytime you start your computer

South Atlantic seems to be more of a GPU hog than CPU. It always 99s my GPU at low altitude while CPU usage is the same as other maps.

[@nemisis_wolf]

It's the biggest map in the game it's huge compared to the others, but still needs more optimisation but they are working on it continuously

[@OberstStruppi]

@spudknocker I am always wondering whats causing your performance issues. One question. Description says 14900K combined with DDR4 3600mhz RAM? Raptor lake is primarily designed to run on DDR5. What board are you on? Since DCS 2.9 i see most often intel users having trouble. DCS Multithreading seems to run pretty fine on AMD, but having almost no effect on intel platforms or causing even trouble. Even though, DCS should run ultra smooth even without MT on your setup.

[@jamisondanecker8186]

@Spudknocker What MBO you got under that madness?

[@adiaprog5787]

So, I already have a base PC, that's running on integrated right now, as I don't have the money to buy all parts at once, and I was considering the RTX 4070 ti super . What are your guy's thoughts on that GPU for DCS?

[@scottw6690]

I have the 14900k as well but have no problems but check your Bios for somthing called Gamers Legacey mode (or somthing like that) as on my Asus motherboard this will turn off the E-cores just by pressing "Scroll Lock" on the keyboard with no need for 3rd party software

[@jamisondanecker8186]

Exactluy MSI pro series MBO also has simmilar

[@JonM-ts7os]

Yup you can do this via the MT shortcut too. I have limited DCS to 4 Cores not all 12 and its a big big difference.

[@MarcTNL]

You explained how to download Process Lasso and how to set up a DCS-profile. Then what ? Do I need to start PL before starting DCS ? Do I manually select the profile ? Can this be done automatically ?

[@ethanb7388]

What would I set for a amd ryzen 5 5600x on project lasso

[@Cosmic89147]

silly question, but does process lasso need to be open in the background while playing DCS or can it be closed once its been set up

[@whiterooksme]

I go a step further and set all other applications to only run on e-cores.

[@StringerCourier]

I had a PC built around the RTX 4090. I, too, was frustrated by the stutters in OpenBeta MT. I stumbled on a process on some forum whereby at DCS startup screen, I go to the task manager, right click on DCS, then right-click Go To Details and then to Set Affinity and uncheck No. 8. It clears up all stutters. Is this an automated way to do this, and is it run at PC startup?

[@shahzinshajid]

I run DCS on a low end PC and get playable framerates. On some complex missions however (such as the ones that come with the Raven One campaign) bug out with certain activations and triggers on my pc whilst working perfectly fine on higher end systems. The Devs reckon it could be something due to the scheduler having a panic attack if it means keeping DCS at playable framerates. I wonder if process lasso could mitigate this.

[@etiennebenhada6710]

Hi Spudknocker, many thanks for your hints. On my side and after sticking to your recommandations.. Still suffer from stutters, weirdly especially flying low over the sea and flying by boats. I apply strictly what you said and it is better but the issue is not completely addressed. Would you mind to disclose your in game settings.. I'd be so grateful, knowing I run a High end PC (I9 13900K, RTX4090, 64GB RAM).

[@barbe6503]

turn your textures down to medium and see how it goes. I can't really tell the difference and the performance increase was huge for me.

[@foobee2]

Does Process Lasso stay running in the BG (and start at boot) or do I need to start it and select the profile for DCS every time I load up DCS? Have you tried this with DCS in VR?

[@Leoric3]

Following...

[@andycarmo5203]

It will run in BG all the time. Once you get the settings for DCS put in, as soon as DCS loads process lasso will run it at Max

[@foobee2]

So, I set it up last night and can report that it does run in the BG, and is set by default to launch when windows starts. I played for a few hours and it did seem to improve performance in VR, far less stuttering, far more consistent. Anecdotal for sure, but it seems to help. Before I would get stutters like mad when on the ground, or when looking at complex geometry for the first time, and that seems to have been mitigated. My specs for those with a similar rig and problems: i9 13900k 4090 64gb RAM Varjo Aero - running at "High" 35PPD Before trying Lasso, running 35PPD would get stutters, 37 or 39 was a complete mess, even with DCS quality settings set to "VR quality". I'll be trying 39PPD and upping the DCS settings to see what's what.

[@Specter0420]

@@joadt to be frank, if you didn't know about XMP there are many other things you've probably missed that could explain the bad performance. It's probably user error. On the software side you should update to the latest mobo BIOS and use the mobo driver utility to get all the latest drivers in windows, you need windows 11 for that CPU to be used correctly, you need resizable bar enabled in BIOS, and you probably need to learn how to overclock and undervolt to tune your system properly. On the hardware side you could have bought slow budget crap RAM (I think 6Ghz is the minimum sweet spot for 14th gen Intel at the moment, but don't quote me). Maybe you have an undersized CPU cooler, bad case cooling, bad cooler mount pressure, bad cooler thermal paste job, bad fan direction\placement, etc. Your best start would be running the quick free benchmark at the userbenchmark website. Allow it to upload the results and it'll give each of your components a "percentile" ranking compared to others with the same PC parts. This will quickly show you if your CPU, GPU, RAM, SSD, etc is underperforming. It gives a few scores so make sure you're reading the "percentile score" with "of 100 PCs with the same components, yours is performing...". Note: It is a quick benchmark and isn't good at finding thermal issues. You'll need overclocking tools like p95, intelburntest and temp monitoring tools like coretemp to check that. All software mentioned is free.

[@Commoner64]

There is still a missing piece to this puzzle. My E-cores have been disabled forever and I still need to disable a maxed out P-core once DCS is running and then re-enable it for DCS to be buttery smooth. There is a scheduling problem in the intel 14900k that effects DCS performance. Hopefully ED figures it out in the future.

[@nemisis_wolf]

It affects all intel cpus from 1100 series onwards

[@nemisis_wolf]

And it's not an ED issue it's an Intel Microsoft issue. Windows 11 is better at working out the scheduling but not by much

[@arkady86]

Unparking your cores should fix it, Bitsum has a nice little program called ParkControl, use that to install the Bitsum Highest Performance power plan and use that power plan when you run DCS...

It's not that you don't want to use multiple cores, it's that DCS only uses a low number of threads (and therefore only uses a few cores), and you want to make sure that it's running on the PERFORMANCE cores, not relegated to the EFFICIENCY cores, because the P-cores and E-cores do NOT have the same performance (as you might guess from the names). Basically, this is making sure DCS gets scheduled to the best cores, instead of, like... Chrome or something eating up the good cores and relegating DCS to the E-cores. DCS is still pretty behind on multi-threading implementation; pretty much any CPU made in the last 15 years has more cores than DCS can use.

[@TheEarthwinders]

Do we need to start Process Lasso every time we play DCS or will this be a permanent change to how DCS runs?

[@daviiidmonza]

There already is a windows feature built in Task Manager under Detail called CPU Affinity, i dont know wy we need another program for fixing this e-cor/p-cor affinity issue.

Unparking my CPU Cores helped a lot. Just in case.

[@StuartBoyer]

This is more important than setting it to all P cores. You can leave it to use both if you do this as a lot of spikes are the P cores waking up from a low state to be used and doing this fixes that and the spikes in DCS.

[@shuntera]

No button for p-core or e-core displayed for me!!

[@whiterooksme]

P and E core only exist if you are running a 12th, 13th or 14th gen Intel. All others, you can just split your cores up to run either DCS or all other active processes.

Not an ED thing is an Intel chipset plus windows I don't know what to prioritise thing. Not much ED can do until Microsoft and Intel come up with a better CPU core scheduling system. As it screws up choosing what e-core and P-core to use on most software not just DCS. Most don't know about it though

[@gonzatricio]

Would this bump up performance on my amd 5950x with a 3080ti?

[@Specter0420]

If it has multiple CCDs, like the 7950x3D, you'll want to lock it to the physical cores (not SMT cores) on ONE CCD. This way DCS will not need to use the slow infinity fabric between CCDs. Basically it'll be the even number cores from the first half of your cores (so 1\4 of your total cores will be in use).

[@Specter0420]

The DCS developers are just getting around to multithreading, like 20 years late. Just in time for hybrid CPUs to be the norm. I guess they'll get around to coding for these in the mid 2040s. The same goes for AMD, especially those with two CCDs with different cache sizes and core speeds, like my 7950x3D. I locked DCS to the physical cores on the cached CCD and realized a massive increase in smoothness.

Sure, BMS is a better sim, and takes advantage of all the hardware improvements of the last decade, latest GPUs, CPUs, etc. Yet DCS is the main culprit of not using all the cores...

ProBalance doesn’t have to be disabled. You can exclude all the processes you want to be left alone from ProBalance. For the rest of them, ProBalance will be able to act on them and lower their priority temporarily.

[@vovochen]

if they have performance and efficiency cores, yes

[@jeffreyc2074]

No this would not help as found looking up specs as of January 23, 2024 "AMD's Ryzen processors don't have "P-cores" and "E-cores" "

[@Specter0420]

Yes it will, but for a different reason. The higher tier AMD CPUs can have multiple CCDs, basically clusters of cores, with a slow "infinity fabric" connection between them. You can use process lasso to lock DCS to a single CCD (the first half of your cores) so this slow infinity fabric is irrelevant. Further, their top X3D CPUs have huge cache on only one of their two CCDs. Flight simulators greatly benefit from the huge cache so you definitely want to lock DCS to the first CCD with the 7900x3D and 7950x3D. I've made a couple DCS forum posts about these issues, started over a year ago and worked directly with the developers. They can't do it right.

[@vovochen]

Thanks! Is the cache also an issue with the 5800x3d ?@@Specter0420
