It is easy enough to remove this or any other plug-in and see if it causes the stuttering. 
One can only assume this was already tried.

Cheers. That gives me something to go on.

from the top menu, plugins then plugin admin, they click the performance tab.

There is also microprofiler under developer, and under settings data out -> frame rate in cockpit.

These will tell you the source of any performance issues, and then you can act accordingly.

Yeah, don't do that, that way is the road to trying a million non obvious things when it was as simple as unchecking a checkbox or moving a single slider down one notch.

As you said, we are all guessing here. I know from experience that overclocking can have the opposite effect of what you search to attain.

Really? I'm surprised at that one. I've only ever seen OC increase performance, not hurt. It can influence overall system stability, needing a reboot, but never hurt FPS.

Actually... thermal throttling might be an issue, but OP's specs include a decent CPU cooler. I have no reason to suspect this is default XP's fault. The vast majority of systems with those specs are fine. Certainly not a stuttering mess with sliders at lowest, as they describe.

Yes, pending more info, lots of guessing. Could be tons of windows processes running in background. Bad driver install. Etc.

I am talking about the stutters. I achieved better frame rates (good) but got stutters with them (worse then a lower FR) due to mismatch with the memory bus speed. I decided to let go of overclocking and enjoy what I got.

of course this is my experience, yours can and will be different…

There are just so many potential places in the beta these could come from that it is much more likely to be something less opaque.

e.g. this, reported 7 days ago

was just fixed in the Thursays update: XPD-13316 – Excessive XPLMGetFMSEntryInfo performance cost.

Anyone flying the 744 before that would hit that the moment they entered a flight plan.

Given clear recreate instructions LR can fix these issues quickly, not using the tools available to actually source the issue and leaving people to mess around with system settings helps no one and leaves potentially solvable bugs festering into release.

If you are using the plugin "Little Xpconnect" try removing it and see if it helps any.

I had stuttering, more like mini-pauses, until I removed the plugin. Then I actually opened the readme.txt file and there it was: 

modify the ini file to include the line

FetchAiAircraft=false

This source of stuttering is gone on my system. Hope it helps.

Story so far:

Vanilla install apart from Volanta plugin, although I've not ever used Volanta in XP yet.

Running at 4K still have stutters.

Monitor is a BenQ EW3280u HDRi monitor. It has G-sync and free sync compatibility but a max refresh of 60Hz.

In sim settings have been adjusted adnauseam and I can clearly see the effect each setting has on FPS.

To be clear, FPS isn't the problem, it is the stuttering that is the killer for me. (I have removed OC and disabled HT but this did not make any difference).

I arrived at settings that gave me 40 to 60 FPS in the Citation X. 

FSR off

Antialising 2xMSAA

Render level High

Objects High

Everything else is maxxed.

I have tried locking the fps at 30 in NVidia control panel and disabling G sync in monitor settings, so it behaves as a normal 60Hz monitor.

I've enabled Vsync in sim and the FPS counter shows 30FPS consistently but the stutters remained.

I tried Vsync disabled and G sync enabled but I'm going around in circles unsuccessfully.

It would be nice if there was an in sim setting to vary the sync speed in the sim settings, like the other popular sim that's the rage at present.

I have excellent smoothness in that and I expect the same of XP 12.

I'll hang back and wait for a few updates before I frustrate myself any further.

developer -> show microprofiler

The graph at the top is the time each frame took. It should be pretty much flat. Also what does the perf tab in plugin admin show?

Also, have you tried it in windowed mode to get a lower resolution?

one of the big todos still for them todo is better performance for higher native resolutions.

If it is that then FSR should help until they get to optimising performance rather than just fixing bugs.

That might be a good idea to see what shakes out.

However this is good information that gives us a view into what you have going on and it's good to know that fps is not the problem but the annoys stutter that happens every so often. 

I have  few question:

Do you have seperate X plane profile from you default that is in you Nvidia Control panel? If not, you should set one up where certain processes should be turn off that could be are interfering with X Plane 12.  If you have how is that set up?

Did you setup your own system, if you have, are you keeping your drivers of your motherboard up to date. I built my own system and use Armoury crate to keep all my drivers up to date. My system performance very well when keeping the chipset and other critical components drivers up to date. You don't have to do this all the time but these newer motherboard have new release drivers have come out from time to time and using Armoury Crate is the easiest way to learn if update is necessary especially after a Windows update.

Lastly, Window update sometimes may trample on your nvidia drivers after a feature update. You may want to check and make sure you running on nvidia driver from nvidia and not the ones Microsoft. Check the version and the dates on the drivers and if they are not nvidia one's, you need to download the drivers directly from nvidia, get DDU and reboot in safe mode and run that utility to uninstall the old drivers and then install the nvidia drivers matching what your suppose to have in there. Also before doing anything take a screenshot of your settings before you remove your drivers so that you can put them back. 

A stutter light that could be a process that is stealing resources to execute more than it should and it repeating because it can't. That could be from anything from mismatch drivers, processes running in the background. When you are running 4K, you need everything to run optimo. You don't see the shortcomings until the system is push to that edge.

I'm wondering if he ever turn off all the plugin and see if the stutter is still there?

My post above is wrong and I'm sorry if anyone spent time trying it. I fooled myself into thinking I had it nailed. It is a known issue and has been reported to LR.

I haven't tried in windowed mode or looked at the dev>microprofiler.

I'll get around to doing it when I'm less hacked off with it.

Cheers for your help.

I don't have a seperate Nvidia profile apart from the edited one locking frames at 30, that is the only mod to the profile.

I built my own system and drivers are up to date, Windows and system. I think the graphics driver is the only one that is slightly outdated (522.30).

I have all other software running great, no system adjustments required or hoops to jump through.

I left all this tweaking lark behind when I moved on from P3D. XP11 runs smoothly locked at 30 FPS, XP12 should do as well... on my system specs at least.

MSFS runs fabulously without any messing about, save adjusting sim settings for best performance.

I'm not wasting my precious time trying to tweak my computer around less than optimal software. It's up to the vendor to get their software to an acceptable performance level.

Having said that, I accept it is still in beta, so I'll be patient.
