I assume you're referring to the app Process Lasso, maybe?

Yes thanks. Will look into this program. I have a 5800x3d CPU and need to see which cores are there onces used the most in MSFS. I already pay for an app to make MSFS high priority in Windows 

Edited April 16, 20233 yr by Bill A

So after some flights I can say that Process Lasso and helped. I have set flightsimulator.exe:

CPU Priority - Always - High

CPU I/O Priority - Always - Critical

what else can i do to improve...I know you can set certain cores for FS or something to that matter.

I now have a 5800x3D

Thanks

I have achieved liquid smoothness at relatively a low frame rate, in all planes I use.

Known Possible Limitations

• Probably need a Gsync display, though perhaps Freesync will work for this as well.

Basics

• ALL other methods of Vsync or framerate lock are OFF, except:  RTSS Framerate Limiter w/ Edge Sync w/ Passive Waiting enabled

Thank you very much for your reply in the other thread (thread on giving lower settings a chance).

Allow me one additional question:

- Passive Waiting is default On in RTSS (and your guide).

- But don't we want to have it Off?

When I read the pop-up help in RTSS, I understand it they recommend to have it Off to get the most even frame times.

I always thought to have it On was a typo in your guide.

I tried both options but so far didn't have enough time for proper testing. I fly with the setting in Off mode and all is fine.

Using FG here with my 40 cards and framerate Unlimited as limiting the framerate results in small jitters.

My displays are Sony Bravia 4K 100 hertz TV’s running at 60 hertz ..

I have it ON and I vaguely remember reading their comments on that and at the time decided my system must not be adversely affected by leaving it On, and all captures are done with it on and I don't have microstuttering.  It's been too long to remember why I left it on I'm sure I tried it both ways and opted for ON.  It's probably not affecting anything because it's never passive enough to manifest the wait.  Try it yourself and see what you find.

Addendum:  just turn PW Off and now see why I had it ON:  big increase in main thread load, around 15-20% or so.  Since I already have excellent FTV I'm inclined to leave it On.  This being said I'll leave it Off for my current flight and see what that main thread impact translates to.

Edited August 5, 20232 yr by Noel

I ended up with better looking captures keeping Passive Waiting to OFF for this flight out of KRSW which is easy on performance, so slightly premature as to what the implications of higher main thread load will do in complex airports.  Of course we can lower frame rate and other variables, but yes looks hopeful!  From start of taxi to cruise we have this, despite the heavier main thread load indicated by RTSS OSD, obviously it had no serious impact on performance.  Next test will do with complex departure airport and see what we can gleen.

Thanks!

 

 

 

Thank you very much for your investigation. Very interesting results so far!

I am now high in the mountains on holidays, far away from the flightsim PC. Therefore I can't look at my end.

When I tried to change the I/O Priority to Critical I got a message saying that was reserved for system processes and it wouldn't allow me to set it. Did you have to do anything special to get your system to accept "Critical"?

I am on Windows 11, are you?

Thanks

I got the same on Windows 11 Pro. Nor sure if its because I used the free version of Process Lasso

Yes, you'll need the full version to make it work.

I do see that the I/O Priority is included in the free version of Process Lasso but it does not fully allow it to be changed on the MSFS.exe. I got some warning and vaguely remember mention of the page file. Other settings mentioned in the thread can be applied no problem to the free version. I have the MS Store version of the sim so unsure if it's q WindowsApps permissions issue?

FWIW, I've stopped using PL because for starters I was getting a significant hit on teh main thread, which may have been a red herring but as you can see above in the frame time captures it's just not adding anything impacting performance.

Does it matter what your monitor refresh rate is set to?

Good question and I'm not sure.  My screen is at 100 but I'll venture a guess 60 would be the same.
