What is your Forrest level and what is your Regional Air activity level ???

Mike, do you have a G-SYNC monitor? Are you using the display port output of your GPU?
There's a bunch of things you can try. I've been working on a Tweaker's Guide for some time now. If you'd like a copy, let me know. @HarryH, Would it be possible to get a copy of your 'Tweaker's Guide' also? Thanks

Mike, have you tried setting the priority for your TrackIR on "High". That has minimized stutters for some folks here so it's worth a shot.
Hope this helps.

The higher the Forrest level, the higher the stuttering close to the ground (I have a 9900K CPU and still use Medium to minimize low flying stuttering).
Anything beyond "Lite" in the Regional Air Activity (in later years) will also cause stuttering because of all the planes the CPU has to keep track of. Plus if you never stray beyond the mission circles, you will never see all the extra planes the higher Regional Air Activity have in the game.

In my experience, stuttering in WOFF is largely due to two main factors, besides variations in individual gaming computers. They are: 1) CPU load and 2) terrain loading.
In regard to CPU load, as PR mentioned above, since there is no spawning in WOFF, the CPU has to keep track of sometimes hundreds of planes at a time, particularly in the late war period. This can occasionally bring even a relatively powerful computer to a crawl. His suggestion to lower your regional air activity from mid 1917 onward is a good idea. You might also play around with Forced Encounters.
Terrain loading also causes stutters of up to a .25 second or so. I believe this occurs when new terrain features or objects are drawn or refreshed in the different "rings" surrounding your aircraft controlled by the compositescenerybudget file. Unfortunately, there doesn't seem to be a whole lot that can be done to ease this source of stuttering, at least without the sacrifice of a fair amount of visual quality and detail. Some people have reported some success by turning off terrain bump mapping in Workshops, however. You might also try lowering forest density to medium, although I can't tell you how helpful that may or may not be.
BTW, these limitations are not the fault of OBD; they are leftovers from the original CFS3 code.

If those stutters truly annoy you, then I would try to take some time and drill down on what it is.
To further pinpoint your issue, I would go through an extensive "test bench". I recommend using a relatively controlled environment like QC, Try flying several test flights and chart your FPS on a software that will record those major dips. maybe use a second monitor and pay attention to when those major dips in FPS occur. Here is what to try and test for those FPS drops:
set your Workshop settings to minimum everything and try with and without the DX shaders. unplug Joystick/rudder/TrackIR/etc... for now, you can tackle those variables later.
1-a QC free flight air start at 10,000 ft in an empty area like Koln.
If you don't have any major dips, then before your next QC flight, increase the workshop graphic/forest settings by 1 or 2 notches and start with (1) again.
2-same, but start on the airfield and take off.
Repeat for (2). Take note of which settings give those major dips.
For #1, you should be able to max out the settings without any FPS loss. It's probably #2 that will show you which setting slams the FPS. If you can repeat that major stutter over and over again, then you've probably figured out which setting it was.
Bonus round: In workshop, set your screen resolution to a very low number like 1280 x 720 and see if that makes a difference.

ORBYX procedures are good, but I would add one more to keep consistence for your benchmark. When you are in QC panel , save it as a scenario so you will be sure to fly the same scenario each time you test.

I set TrackIR priority to "real time" - this helped somewhat, but I still get these stop-start stutters. My sense is it's game-related because I still get them when TrackIR is off. Seems they are worse earlier in the mission and as time goes on I get fewer. It isn't a slide show by any means, but I do notice them. Just sort of strange to me that I have FPS that I consider to be pretty high, but the smoothness isn't there that you would expect for that FPS level. Try using Nvidia Inspector to set V-SYNC at 1/2 refresh rate and set your refresh rate to 144Hz. This will translate to a 'capped' 72FPS which the old CFS3 engine seems to like. From there, given a decent CPU and memory, things should improve. Better to have a lower (above 60FPS) but consistent framerate than a framerate that bounces around from screaming fast to momentary slowdowns. Again, all this is covered in more detail in the tweaker's guide.

. Another very significant area to look at is antialiasing. The in-game antialiasing is a big performance hit, even at 2X. If you have an Nvidia card, you definitely will be better to offload it. Set the card to override game settings using Nvidia Inspector and then apply GPU antialiasing settings... Was just reviewing this thread as it was linked to another, newer discussion and found your recommendation Harry. This is interesting as I have tried it both ways on my older system and found that setting the in-game AA to 8x and telling my Nvidia GPUs to use application settings resulted in much, much smother game play and much nicer looking visuals. Every system is different that's for certain. .

I'll just add my recent observations to the thread.
In general, I hadn't been noticing many (any) stutters; but most of my flying has been without combat (I've been doing free flights to admire the scenery and getting the feel for many of the planes in the sim). Without a gaming monitor, my system generally holds a steady 60 FPS. Recently, rather than free flights, I've been doing turkey shoots to add a little combat at the start of my free flights. The results is that I've been noticing some stutters. They mostly occur when machine gun hits happen (usually the first few hits). To me, this reinforces the idea that it's related to one or both of the following effects: (1) additional CPU usage for damage calculation; and (2) loading of skins for the damage visual effects.
The thing that brought this to mind was an old stutter video (posted in another thread because I don't see it here) which had a stutter at the same time (first hits). As I said, this is just my observation.

As I said, this is just my observation. Welcome mandrews, good to see another new face here. I believe the general consensus around here nowadays is that any number of things can overburden the somewhat limited CFS3 plumbing system and cause less than perfectly smooth rendering (see RAF_Louvert's recent thread on the subject). However, your system spec is pretty reasonable. Do let us know if you ever feel the stutters cause you to get killed in combat. That would be interesting info. Also, keep in mind that, when you graduate to Campaign mode, the air density setting becomes very important as a tool for limiting problems. Basically, don't shy away from using light or very light settings. You'll still see action.
