Hardware-wise, especially including your display, says to me you should have absolutely no issues at KPHL or anywhere else in the PMDG 37x.  Here's my recommendations for you:

• It's worth setting up this approach here.  It's a little lengthy to read thru but actually is simple to set up.  The main piece is in my signature:  RTSS Framerate Limiter w/ Edge Sync for near zero Frametime Variance achieving ultra-fluid animation at lower frame rates.  There can be a subtle visual aritifact if your screen doesn't do Gsync, but it's worth a look because setup is very simple and quick.  I used this approach quite a while prior to picking up my Gsync display it's that good for delivering ultra smooth animation at modest frame rates.

  • Definitely follow the setup at the end of the post to allow you to alter frame rate lock in realtime w/ the press of a key.
     
• Install the DynamicLOD mod as mentioned.  This is the main key to sustaining a base frame rate while on the ground in complex terminals in complex planes, which in your case would easily be 35fps.  You CPU turbos to 4.9Ghz.  Terrain LOD is far and away the most demanding setting for your CPU.  You will be able to have TLOD very low while on ground and the higher you fly above ground TLOD will increase w/ DynamicLOD.  NOTE:  don't be fooled into thinking you can get away with very high TLOD--at the highest levels above ground I'm maxing out at about 170.  Fortunately the difference visually isn't much.  I use all 3 available profiles in DynamicLOD.  For my most demanding airports will start w/ TLOD at 20 while on the ground.
• Use the TAA antialiasing routine for sharpest visuals and your GPU should handle it no problem.  I also recommend setting NV Control Panel's DSR factors as high as you can get away with, which for me is 4x.
• Set all other settings in MSFS to Ultra.   
• FSLTL I highly recommend:  you must keep traffic levels well controlled as this is another big load on your CPU.

Thanks a bunch for this, greatly appreciated! I figured it was my lack of knowledge in configuring the proper settings. I’ll give this a go and see what happens. I’m confident that this will provide improved performance. FWIW, my performance is usually pretty good in the not so dense areas, but  as you said, I still should be able to get decent performance in the more dense areas. 

Cheers, Pete

One last comment:  high frame rate doth not insure stutter-free animation, though it can certainly help mask stutters.   IOW you always need to respect the limitations of your hardware and how the simis configured.  There are also I have found sources of stutter that really have little to do with your setup, settings etc.  My guess is these are builit-in potential issues that are not related to overloading your CPU and/or GPU.  It's rare for me to hit one of these situations, they often don't last very long but can.  I always reboot between flights to start w/ a blank slate each flight.  It's almost always the case now I'll see only a hint of a stutter once or twice per flight. 

I trialed the Frame Generation mod and it was nice enough to make me look forward to RTX4090 which will go into my next box UNLESS MSFS 2024 does something magical to reduce VRAM demand.  That being said, the FG mod came with some significant untoward side effects making it not worth the benefit of high frame rate, for me.  Worst of all clicking the mouse on the main MSFS display after interacting w/ a 2nd display connected to the mainboard's iGPU made the whole main display judder.  Connecting both displays on the 3080Ti created an even worse side effect despite matching refresh rates in the two displays.  I'm very frequently going back and forth between the two screens.

Good Luck Pete ;o)
