Ultimate Smoothness at Modest Frame Rates

40 FPS works with 120HZ panel, if 60Hz panel, use 30FPS. Everyone has different standards here of what we think is "modest" "average" and "good" and rightly so. I have a 5800X3D and a 3090, but I run 4K, medium to high at a locked 30fps on a 120hz panel and it is stutter free. It's a game of diminishing returns the higher you push framerates and graphics quality, so you have to find a balance.

OP should keep up-to-date with people's opinion etc and we can have an all-in-one optimisation guide, although it does vary slightly for everyone though.

One of the cool benefits of the approach I'm using is that one can limit to whatever framerate one believes they can fully sustain from gate to gate and it is no longer necessary to use the divisors in MSFS (which I did for 2y).  IOW you're not locked into even divisors of your refresh rate.  My screen is set for 100Hz, and yet I can set at 33, 35, 36, 46, etc.  I tested all permutations of this including what you're doing w/ whatever sync method demands you use divisors and none create the kind of ultra low FTV that RTSS' method described does, and this has been the key to ultimate smooth animation at low frame rates.  If I come into an airport that appears to threaten my frame rate lock I might toggle the limiter off w/ the hot key and get all I can out of the hardware.  For example if unlocked yields a rate of say 37fps, and I'm locked at 34, I'll just toggle the limiter off (as described is done in RTSS w/ no need to stop the sim, with a simple hotkey assignment) while on the ground or near the ground at arrival as this is often where the most stress comes--in arrival, v departure airports of the same complexity.

If you care to test what you're seeing for FTV, use CapFrameX.  This is how I established this method is fundamentally different from all other syncing methods.

They should show up in PL as you set them in Task Manager. No need to reset.

Thanks.

No, when you set them in TM they restore to unset after rebooting.  So just reboot, then do you setup in PL.  I don't have PL start with Windows because it prevents MSFS from launching, at least on my system and at one other who mentioned this.  So I launch PL (w/ its configurations already set) after I'm pretty much at the gate.  Also, it can be shut down after initializing and all settings will be retained, until you reboot and repeat the procedure.

Thanks for the info. Regarding TM, I'm actually using a mod that maintains any values changed, hence, my initial question.

Oh, well why use PL then?

Mainly for the more intuitive UI and the ability to group change affinity values. And to give it a try as it's free.

It's a slouch compared to RTX 4090

The 3080 is not a slouch, it's a high end graphics card and pretty much overkill for 99 percent of the resolutions that the average simmers run. 

KoolAid from Nvidia - don't fall for it by drinking itl.

I never succeeded in doing so. How do you accomplish this? (Obviously I must have been overlooking something).

Pretty much like any Windows group select operation:  click the first process in the list of processes, hold the SHIFT key, scroll to the bottom while holding the Shift key down, then select the last one, now all are selected.  Go to CPU Affinity > Always, and make your changes.  And of course remember to set MSFS as the exception to the others.

Ultimate?, perfection?, sounds familiar

Im sure its very good

Thanks, Noel, I several times attempted to do so, but failed as the processes scrolled very fast away from me 🙂 But will give it some other tries.

Just want to say thanks so much for this valuable information! I was skeptical at first as I have a very modest system: Corsair ONE,  Intel Core i7 8700K (3.7GHz >Turbo Boost to 4.7GHx); GPU nVidia GTX 1080Ti; Samsung 39"  Generic PnP Monitor (1920x1080, 60hz); ; 64GB Memory (DDR4; 2133MHz); Honeycomb Alpha Yoke; Saitek X52 Joystick & Throttle Control. Anyway, I followed your instructions to a "T" and I am getting a solid frame rate of 33 (my RTSS Frame Limit)  through all phases of flight . That is also with FSLTL, FSRealistic, Pilot2ATC & Fenix A320 running at EGLL. I have also implemented PL and have assigned Cores 0-11 to MSFS (12 Cores) and 0-10 to all other Processes and apps. So thanks again for sharing this information with the community.

Regards,

Tom

I’m intrigued...I have a 10900K and RX 6800 but will get the occasional hard stutter and rumble/vibration from the PC at times as autogen or something loads.

And I have a Process Lasso license.

I think I see where I assign affinity to MSFS but it seems like I have 0-19 available  - which cores should I assign to MSFS?

How can I force “everything else” to use other cores?

Thanks!

I have 20 cores in total, of which 8 cores are hyperthreaded. I might be worng, but I assigned MSFS to core 12. Perhaps core 20 would have been better? What do the experts say about this?

right ok - so you removed Core 7 from other processes ?  How do you know Core 7 is your main MSFS thread ?

MSFS runs on the last core be it logical or actual, and this is easily corroborated using any number of core load monitors such as MSI AB's OSD, and Process Lasso shows dynamically all cores running.

The primary reason for this was to get certain processes away from the main thread, in particular audiodg.exe I think it is called and a few others.  I noticed this was the pathway to losing the associated microstutter when ATC text/voice happens.  These may contribute to other sources of microstutter or what have you, and there is no downside except you must run PL before starting MSFS else it may/will not load.  So that is the last step in my flight setup, to run PL.

As I use PL its purpose is to take other processes off of MSFS' main thread.  You should be able to identify which is the main thread simply by looking at PL's graphic core % in use display on the upper right part of the PL window. 

You will keep ALL cores available to MSFS so in your case 0-19 I assume you have 20 cores so MSFS gets 0-19.   All other process you will assign to all processes except the main thread's core.  You can also change MSFS' CPU Priority to HIGH, as well as MSFS' I/O priority to HIGH.

Can I assume that the above should read, "...except you must NOT run PL before starting MSFS else it may/will not load." ?
