Rather than describe my experience, I thought I’d show it. The following 4-minute video was taken this morning, showing the Flight Design CTSL flying around Dallas - Fort Worth (KDFW). I chose KDFW as representative of a large airport, but not as extremely complex & busy as, say, KJFK.
As the specs (below) show, I’ve pretty well maxed out every setting in the game, deliberately trying to stress the system & induce stutters, which you will see at various points. Note that, in-game, they were visually not so apparent - the recording process appears to have amplified the effect somewhat.
A flight taken last night from Amsterdam to Lydd in the UK via Ostend had no stutters at all, but live traffic was disabled for that flight, so there were few AI-aircraft at the airport at Amsterdam.
The video framerate is 60 FPS, the same as the in-game FPS. There are 2 overlays shown that show what is being processed by the GPU. Note that the Windows Game bar (running, but not captured) showed double the frame rate than that shown by the Arc telemetry.
The video does not show what is happening in real-time on the CPU, but I captured the following screenshots showing CPU logical processor and other usage:

Using the same settings for the Daher TBM930 & Boeing 747 resulted - unsurprisingly - in a FPS drop in the Boeing 747 cockpit, but other parameters were similar in all 3 scenarios:
| Cockpit View | Flight Design | Daher TBM | Boeing 747 |
|---|---|---|---|
| Overlay FPS | 19.2 | 19.5 | 13.4 |
| CPU Utilization % | 23 | 26 | 23 |
| Memory Utilization GB | 15.6 | 15.4 | 15.4 |
| Airport View | Flight Design | Daher TBM | Boeing 747 |
| Overlay FPS | 20 | 15.6 | 15.3 |
| CPU Utilization % | 25 | 26 | 25 |
| Memory Utilization GB | 14.2 | 15.4 | 15.4 |
