Just in case anyone is still looking at this info, I haven't done an exhaustive test, but the last few times I tried, the reduced FPS episodes I was seeing seems to have either gone away or been significantly reduced after the latest update (.11). I flew the same mission I had consistently seen it in (A-10A Push Back), and did not see it at all, except in one brief moment where it seemed to drop from 60 down to the 50s, but that may be unrelated.

Hi Limaro, I am seeing the same - I'll get pretty solid rates around 80-90, with bursts of over 100, then when flying over certain areas, it drops to the low 30s. With V-Sync I get a solid 60 and then it drops down to 30. I get tearing without V-Sync, and it generally seems a little smoother with V-Sync, I prefer to keep it on.

Just in case it helps to analyze performance settings, I changed a couple of things, setting the terrain shadows to flat and reducing the anisotropic filtering to 4x, and it did seem to improve performance, but I still can't figure out what would cause FPS drops in certain situations. Here's a video I recorded where simply zooming an external view slightly impacts FPS. I have V-SYNC on, so maybe that's why it drops to 30 and not somewhere in between, but it seems to be OK at in-between levels in other circumstances.

Thanks for the feedback, and I'm still not sure I understand the impact. In the A-10A Push Back mission, I can fly over a certain area - that has some buildings roads, inactive enemy vehicles and trees - early in the mission and it's fine, but later when that area is in view, the FPS drops to about 20. It is after the vehicles activate, so I thought it might be A! related, but even after I destroy them, the slow frame rate remains. The light, shadows, number of objects, etc., don't change, but yet the FPS mysteriously drops partway through the mission.

As mentioned, stuttering is difficult to track down, but on my new rig, I had stutters and found two ways to fix them. One was related to TrackIR, and disabling hot plug devices in the controller screen (in the lower right) helped out a lot: Another thing I found that seemed to smooth things out a bit was to set a maximum FPS in the Nvidia control panel. That setting was off, so I set it to a high FPS, and for some reason, it seemed to work a bit better after that (placebo effect, maybe?): But I still have weird FPS drops. Here is a video where you can see the FPS in the upper left corner. All I do is look around, and it goes from 60 to 20, and it happens while flying as well. I can't figure out what is in the view that is slow that bogs it down. And that's on a pretty beefy system, 12700K, 2 NVMe drives, 32GB RAM, RTX 3060Ti video card. The 60 FPS max is because I have V-SYNC on.

I'd like to add here that I recently picked up a new gaming PC with an i7 12700K running Windows 11 and had a major stuttering issue, and in researching it found this thread and used the disable hotplug button and it fixed it, so I appreciate the info here, and the addition of the button - thanks!

Yep, same thing here. I'm guessing we'll have to re-map them... I take it back, after a restart is seems to be working for me.

Very nice - thanks for the link!

Thanks everyone. Iguana, I had no idea about the history of that A-1. You get to work on an interesting selection of birds! I think the guy who owns it keeps it at Ramona, but I'm not sure. Ramona is a very small field about 40 miles NE of San Diego.

A local airfield in San Diego, CA, had a small air show this weekend, and had a few interesting aircraft show up. Not a big show, and a little slow moving, but it was still a nice day to see some fairly rare planes flying around.

As an owner of the eDimensional glasses, I'll just second everything that Ven said - I bought 'em years ago and stopped using them because they didn't work properly with a lot of stuff, and Nvidia stopped doing much to support them.

Could be they're just burned out, or maybe the top veteran teams are still deployed. Or maybe the Turks and Jordanians just work harder in training for that sort of thing and are consequently better at it. I guess without knowing more about the event it's hard to put any meaning to the conclusions, other than the Turks and Jordanians are definitely good at what they do.

Somewhere someone had a link to that in a downloadable format, and I pulled the highest quality version of it they had and burned it to a DVD, along with some Lock-On movies, to demonstrate to some friends the evolution of flight simulators. I thought it was pretty cool, but they mostly just thought I was a nerd after that :).

Very nice stuff there. Thank you!

Here's a few Thunderbird shots from their show at Nellis a few years ago to give you an idea of their show (a lot like most military demo teams, but maybe a bit faster):
