Flying the TBM 930 at FL20 on a HDG course over the high desert in California with a FEW clouds and no other addons.  Settings on HIGH with NO Frame Gen (just for simple record keeping), NO VSynch, NO frame rate limiter.

External Camera slightly above and behind the plane and Cockpit Camera from Left seat wide angle. Following is a sequence of views and the dramatically changing FPS and CPU load

Outside view 60 FPS 9ms main thread 59% GPU load

 Inside view   30 FPS 12ms main thread 69% GPU load  

Inside view looking out the window 15 fps 67ms main thread 80% GPU load

move outside  31 FPS 31ms main thread 77% GPU load (same scenery/clouds as first outside view 60-seconds earlier)

Change settings from HIGH to LOW and back to HIGH without ever resuming

Outside view 60 FPS 9ms main thread 59% GPU load

And that cycle keeps repeating

Moving inside cuts the FPS in half and more than doubles the CPU load and it does not return to the starting outside FPS and load

What is the sim doing and how to I keep a reasonable frame rate?  A 64GB 9800X3D and 12GB RTX 4070S should be able to consistently produce 60 FPS at high settings in easy scenery.

correct error

Are you on the latest GeForce drivers? This driver feedback thread has a few posts from people having issues with GeForce drivers since the release of the 50 series, at least in 2024.

I'm having the same issue with this driver in MSFS 2024 as I do with the previous driver. And that is, using this driver results in very high CPU usage while flying in Free Flight. CPU usage is normal with this driver in MSFS 2020, but very high in MSFS 2024. Using driver 566.36 results in normal CPU usage in both MSFS 2024 and 2020.

Quit worrying about frame rates, enjoy flying in a smooth sim with great scenery.

Yeah Right!

Just flew into KBFI (Boeing Field Seattle) on ILS 14R in the TBM 930.

Settings on High - had been seeing 75 - 90 FPS (FG on) all the way down the approach to 1000' when suddenly FPS drops to 25 and keeps dropping,  At the threshold I was seeing 10 FPS and at touchdown 3 FPS (FG still on).

That sort of variability makes flying impossible and unpleasant. 

I fly into KBFI many times a week and until today have always had good frame rates and scenery.  Today, at my PC, seems like a reversion to the early January period of wildly varying performance.   My system with all sim stuff coming off NVMe drives should not be at 3 FPS no matter how intense the scenery. 

I am on nVidia 572.16

Despite the possible performance issue, the latest driver seems a bit cooler on the GPU

I’ve seen these massive FPS changes as well when changing views. It does make it a bit tricky trying to tune settings for best performance.

If it helps, I fly into KBFI and nearby airports a lot - what got me to zero stutters was disabling the default KSEA in the "Marketplace" (all the rest of the scenery is default, I disabled all my Drzweicki content for now).   Researching my stutters (which may be different than your total FPS drop), it seems that the "streaming" of a higher detailed ASOBO airport like KSEA or KLAX can cause the stutters (and KSEA is very close to KBFI, so it loads in).

In any case, I lost the stutters and FPS drop.

On tests of takeoff to the south from KSEA and landing on KBFI 14R I also found that the PLANE used had impacts at least on my rig - certain planes (even the default 747-8) are terrible while others (like my Flysimware Lear 35) are flawless, the default 737 Max and A310 and Cessna Skycourier are very smooth.

10900K and 3070 on my end.
