Description of the issue:
It’s the second time in a day that this occurs:
on 737 max, after climb, I set the cruise and then 4x on sim rate; most of the times it flies smoothly, but sometimes I get an hard fps drop like in the first screenshot I posted while I usually am at 60+.

Hello :wave:

Not sure this is a “bug”, per se.

In my understanding (of a tech guy not working at MS/Asobo), the world (terrain, traffic, weather) is being downloaded and processed as you fly it. It’s not new to FS2024, in 2020 already , it was not “downloaded” but “loaded from the disk” (only the rate “downloaded / loaded from the disk” has changed).

On most of the computers / internet connections, running at SimRatex1 will go smooth : your computer (and connection) have enough time to download and process things before you see it on your screen. But it’s on the edge for many computer (not ours; I, like you, have a pretty good config).

On SimRatex4, there are things that have been downloaded and processed that are behind you. Your simulator is precessing things it doesn’t require anymore but which were in the queue and still had to be processed. And what you have now in front of you has not yet been downloaded/processed, and that’s were lags come from.

That’s why we see that everything goes right for a few seconds (the computer can cope), then things are getting harder (the computer can’t cope anymore).

If it’s to been seen as a bug, I’d say that “SimRate increase” should make it that we download less things that usually. I doubt this one is going to get any proirity though, as I see it, it’s more “a simrate limitation” rather than a bug.

Cheers
K.

Expecting the performance to be the same if you want to have all the calculations in a quarter of the time as normal is a bit illogical, isn’t it?
