Does anyone know if there is any good documentation and/ or YouTube Video that explains how to use Process Lasso and MSFS?
Thank you
I use it generally with my older PC. I think there are things you can do to give more precedence to some apps that others but I just let mine get on with it with the basic settings and it seems to smooth out lockups and so on.
Here is mine:
Main menu: Performance mode enabled ProBalance/enabled
FS exe right click menu:
Priority class/always/high
I/O prioity/always/high
Application power profile/Bitsum highest performance
CPU Limiter : When CPU use is: 98% Reduce: 1 For a period of: 1
More/Disable IdleSaver

Can you please explain what this does? Also, why “high” instead of “real time”. Thanks.
Since then, it has proven to me that using Process Lasso is unnecessary, not a real benefit to FS.

Yes, I believe that is true too. If there is any difference, I cannot detect it on my system/set-up. Charles

I know, necropost. Ive been having some issues with Process Lasso and MSFS since migrating to Windows 11. Without even touching it, Process Lasso will kill MSFS2020 during the loading screen and I cant figure out why. I dont use Process Lasso for MSFS at all since its pretty much unnecessary, but absolutely is for using in VR playing DCS. Might just be best to ditch one of the 3.
working excellent for me on Windows 11.
It’s just another snake oil remedy IMO.

can you let me know your Settings, I use the programm since 1,5 years. but I’m not sure, if I use the right settings.
Many thanks
Real Time is never suggested. MSFS (or any foreground program) is never alone on the system and Real Time can slow down or even stall support programs which MSFS depends on (think about AIG, GTN750, not to speak of VR support, and the like).
I have been using High with any Flightsims for ages.
On Process Lasso, I think it detects itself programs in need of exclusive resources and configures them appropriately. At least that’s what I suppose, but there may be room for improvement.

I know this is an old thread but my question fits exactly. I bought a new Intel i7-13700K / Nvidia 4080 based system (detail in my profile). I have been using Process Lasso with the Bitsum Highest Performance Profile. The whole system works excellently, not to say perhaps slightly too good.
When checking CPU temperature I found it’s >90°C most of the time when simming and often even close to 100°C, where it’s throttled down.
I get > 100 fps (using DLSS) on the 2D screen when running with Process Lasso but around 60 fps without it (same settings and situation). The reason is clear, I am CPU-limited (as are most of us) and the GPU could push out more but the CPU is lagging.
As I said, the system is running fine, but I am concerned about CPU temperatures. There are different opinions on this, though:
The author of Process Lasso claims in a slightly older forum thread: “any properly built PC should be able to handle even a 100% CPU load indefinitely”.
Contrary to this, you often find the suggestion not to exceed ~85°C, and never exceed 95°C. Even if it runs, it will shorten the lifetime of the CPU.
Since detecting the high temps I exit Process Lasso when simming, but with a mixed feelings. Is there a suggestion to use Process Lasso with a more mild setting where the CPU runs at, say, at 80°C maximum?
Well, your issue is not ProcessLasso, your issue is inadequate cooling of your CPU. Buy a decent cooling solution (Noctua Air or AIO Watercooling). Everything else would be reducing the power of your CPU to lower your temps. So, better get a good cooling solution.

So, yesterday i spent some time to optimise my system, especially CPU (i7-12700K), so i dont have to spend a lot of money on a 7950X3D 
What i knew already, is that MSFS and for example the FENIX AddOn dont work very well with the E-Cores. That means, E-Cores disabled gives me better performance than running the CPU with them enabled.
But, its kinda stupid to castrate a 12-Core CPU to an 8Core and dont make use of features one paid for, so i did the following:
Installed ProcessLasso, created a “default” profile with no changes and then created a “MSFS” Profile, so i can easily switch depending on how im using the PC.
For MSFS, i just started all the programs i need when using MSFS (Volanta, Spad.Next, VA-Tracker, AVIA Server, etc.etc…) Then i just selected ALL running processes with Ctrl-A und put them all on the 4 E-Cores. MSFS.exe i assigned, of course, to all the P-cores and giving it high priority and a high performance powerplan. All the FENIX processes also went to the P-Cores aswell, as most of this AddOn runs externally as processes (Display rendering etc.).
The result was amazing! A big improvement in FPS and most importantly, a very, very smooth experience with lots of short stutters/hickups gone!
Tought this info is important for every 12th/13th gen Intel user that wants to get the most out of their expensive CPUs.

Can you explain how you set specific processes to certain cores? Is it simply via unchecking and checking what cores are on or off in the CPU Affinity menu? Thank you. I’m trying to optimize as much as I can for VR.
Does anyone have any experience with Process Lasso in combination with the new 7900X3D and 7950X3D processors? After all they come with special drivers to keep the two dies working seperately, and it seems those really improve the way the workload with MSFS is being distributed to multiple cores. So: is Process Lasso even still a good idea?
Thank you for the detailed write up. I have the same CPU and was wondering about the configuration/use of the E-cores.
Thanks again!

Thank you for the testing/results.
Now, my thoughts are more focused on stutters or micro-stutters rather than FPS. I’m going to try some tests with the CapFrameX tool as soon as I have time to.
