I just did AI Overclocking and it has reached 5.3Mhz. Same test, same result.

What is your memory speed?  By that I do not mean the specs of the sticks, I mean what is it actually running at?

Go to Task Manager, Performance tab, Memory subsection -- it should say Speed:  and then have a figure like 3600 mhz for example...

2133 Mhz

You need to first do as others said, run some benchmarks outside of MSFS. Check your temps, if the CPU or something is overheating badly then it may throttle the entire system and there won't be enough CPU power to allow the GPU to use any real power. Though this is pretty unlikely unless the cooler was installed incorrectly or something. Regardless, you still need to run some benchmarks. Triple check your power-performance settings, ensure it is on maximum performance. Check for any FPS limiter setting, and turn it off. Check your temps, etc... Having people check FPS at specific airports isn't going to mean much.

Try these:

3D Mark

Another one:

You can also try Passmark:

If the tests show up as within a relatively normal result, then it could be MB issue with the 4090 causing threading priority problems, as the 4090 is very new. Driver issue or MB BIOS might need updated, but both these are extremely RARE issues, so I kind of doubt it.

That's low, but I don't think it would cause a result that bad, not by itself.
It should be at least 3000 generally speaking, but I didn't look at all your hardware that carefully.

That might cause a 20% to 25% hit in performance overall, but probably even less.

Also, turn off NVidia Reflex and the AMD stuff, turn off everything that is NOT absolutely essential in the MSFS settings first to get a clean slate, but leave all the rendering stuff on Ultra. Reboot and restart MSFS.

So no repeatable publicly available standard benchmarks have been run yet ?

No ?

Ok

 

Good luck

I will repeat what several others have said:

You need to run benchmarks!

You need to get results from standard benchmark tests on your CPU and your GPU. You need to determine if your system is performing as it should, or if there is some general problem with your system.

Only after that is done and has shown a conclusive yes or no, then you can start troubleshooting MSFS performance.

I go to that. I've had to deal with some work stuff and keep an eye on here. Ha ha. I'll post the results in a few moments. Thank you so much for following up and helping.

When I installed the 4090, I had to clean the BIOS and some settings were gone. I had not realized it, I have already done OC XMP 1 and it is already at 3600 thanks for that tips

So you're no longer at 2133 mhz?   You are now at 3600 mhz?   That's a step in the right direction...

Alpine yes 2133 to 3600 could be a very significant improvement...

Now I'd love to see the benchmarks.  I bet since you have your 3600 mhz speed going, your sim and benches should be better.

I bought a seasonic prime tx1300 with two dedicate power connectors so don’t have problem with

will try tomorrow as I ´ll receive my new screen 

Guys, can't run 3dMark, just installing it freezes PC. It seems according to some forums, that it is normal when hitting with other software.

Here they recommended PassMark These the results

I am not an expert on the subject but surely you will have your comments on the results.

I want to share the images of how the Nvidia Control Panel configuration is and if I should make any changes there.

I confirm that my memory is now at 3600 mhz

Things use buffers in the VRAM on the GPU itself, that is why RAM doesn't make that much difference. It can in SOME games that are coded odd or using off-brand game engine. I'm being overly generous when I said ram might make up to a 25% difference in FPS, it could, but  unlikely in MSFS using a modern game engine. Even if it's 25%, that wouldn't explain his performance.

Everything looks normal to me in those benchmarks.

I think the issue then may be in the MSFS?

Did you already try running the monitor at 60hz just for process of elimination?

There have been some bugs with certain things at 144hz.

Why did you install SU 11 Beta if you knew you were having issues.
Use SU 10 for POE...

Without being there and checking it myself, my best wild guess...

Motherboard with that card combined with Windows 11 triggering threading bug in MSFS. I hate to make such a guess, because this type of problem would be incredibly rare, but none of this makes sense to be honest.

Maybe try Windows 10.
