ehr… wow.
Like you, i do believe you have an extreme system, you’ve dumped enough money into it for sure! (are you a graphical designer by any chance? wow)
In the next update, multiple monitors will be supported, so for now, breaking out a second monitor is the main fps killer for most… but i seriously haven’t heard of Multiple GPU support so far, as even i thought that running duals like the previous SLI was a thing of the past with these more powerful cards, certainly the 3090’s… it almost feels like the second 3090 is trying to overrule the other 3090, so is there any software running to keep the two of them working together?
And no, i have no experience with your setup at all… but i am however curious enough to post a daft question:
What psu are you running to keep that system activated and, just to keep a happy note, what type of generator/powerplant is outside your house… as that is certainly a VERY beefy system. This one is way out of my league, Demariners, but my other question would be, what other games are you running on this monster?
Without knowing any of your settings, and the fact your question has been pondering for 5hrs here, here’s what i’d start with: (and i have no clue if you’ve actually checked everything, or that you’ve only focused on what’s inside the game/sim… sometimes even reverting to a newer or older graphics driver, ((be sure to do a clean install)), might actually help)
The main “eaters” of FPS during gameplay are indeed your pixels, your monitors hz (if there’s a difference in hz throughout the monitor setup, i do believe that might kill quite some more fps as the GPU is trying to keep them up to scrap at whatever the cost) then ingame the pixels setup needs to be the same as the monitor, so full screen resolution, needs to be the same as the render scaling to start with, if there’s fluctuations, the gpu will try and compress or decompress the textures which eats up render time. Stretching flightsim over multiple monitors has been proven to cause severe issues, but you mention just using one is already causing issues. Btw, have you tried Hags on/off? (usually the performance of 3000series cards warrants hardware accellerated gaming to be on, whereas the older gens need this setting to be off in windows settings.
Also, with the newer monitors, when turning them off, they actually eject themselves from the system alltogether, so the gpu’s dont actually render for them anymore… my older/secondary monitor, actually stays in the system when i turn it off, whereas this newer 3440x1440 actually ejects itself and no longer shows in my nvidea driver settingspage or windows itself… if yer not using 'm turn 'm off?!?
That’s all i got for right now, sorry.

ps: You’ve mentioned you’ve played around with the settings from Ultra to low but that’s actually the final tweaks after you get the basics right.
