So, I’ve recently been having a strange issue the past couple of weeks. It doesn’t happen every time I have a flight in the simulator either. I’m pretty sure it’s only happened when I fly airliners so far also (i.e., Fenix A320, inibuilds A320 V2, inibuilds A310, etc). Sometimes when panning the camera all of a sudden it gets choppy and stuttery even with a stable and high framerate. My new system is only two months old, so I doubt that is the issue, it doesn’t seem to be a performance issue either as my frame rates are good and I have a beefy system. I really don’t know what to do. I saw someone else posted a video on reddit of exactly what I’m experiencing but I can’t seem to find it again to link to this. Anybody have any experience diagnosing and fixing the problem?
System specs:
Windows 11
RTX 4080 Super
i14700KF
32GB RAM
2TB SSD Hard Drive

I’m getting it too.
I don’t think the problem is on our end of things.
Are you using frame generation? If so press Alt + Tab then press Alt + Tab again.

That’s one of the main reasons why I stopped buying tubeliners. It’s just not a smooth experience and then add AI traffic and photogrammetry it’s a choppy experience.Drop your TLOD to 100 if you haven’t done so.
Here are my specs. 5800X3D RTX 4080 Super 32GB.
I think I know what OP is talking about and I’ve only seen it with frame generation enabled on my PC with an RTX 4080 Super (saw it last flying the Black Square Duke). On my PC with an RTX 4090 I haven’t seen this. Might be VRAM related if you’re trying to play maxed out at 1440p and above. I can’t think of any other reason.
Do you have “Off Screen Pre-caching” set to ultra? If not you may find it smooths camera panning.

It’s happening even when VRAM isn’t maxed out. I can be using 12gb and it still happens. Lowering TLOD seems to get rid of the stutters.
If I fly with photogrammetry off it goes away.
Fair enough. Personally I play with TLOD at 400 and photogrammetry on and haven’t noticed it on my PC with an RTX 4090. Would like to note that these days I don’t use the in-game frame generation. I use the Lossless Scaling app as I’m seeing better results.
The simulator is highly optimized to deliver solid FPS with as little stutter as possible. It preloads terrain ahead, etc. The moment you pan around, you disrupt that process, and it restarts. Pushing the graphics pipeline (as you do with high FPS) this will have a visible effect. On some systems more than on others. If you are pushing the graphics pipeline to the max, it will need a lot of time to catch up. You see more of these issues with the higher-end graphics cards because they are so good at delivering what the system expects to deliver.
So, it is ‘normal’ behavior, but if it bothers you a lot (it does not for me), you could aim for a slightly lower FPS and ensure the sim is not limited by the graphics pipeline but by the CPU.

I appreciate all the replies from everyone. I’ve been doing a lot of experimenting and it definitely seems frame generation related. I noticed once I go back to Direct X 11 with no frame generation the problem disappears albeit with significantly lower fps than with frame generation on. Sidenote also, heavily detailed pay ware airports that seemed to take a while to fully load and appear in the simulator are also fully loaded as soon as the flight starts with Direct X 11 enabled. I thought that was pretty interesting.
What would a lower fps setting be?
