Poor Performance with NVIDIA 4090

It's almost invariably the simmers with ultra high-end systems who report all the performance problems, because they overdo all their graphics settings by a mile, believing they shouldn't have to compromise after their expensive purchase.

What is overdone about the OP's settings? They even use DLSS instead of TAA.

Also, it's almost invariably the simmers with low-medium systems who have to pounce on these topics like vultures when they can't actually say anything to the point.

I'll admit I was a bit harsh in my response, and not only that I agree that there is more than a potentially lacking PSU situation but failed to so state.  When replacing an AMD gcard with an Nvidia one really needs a DDU deep cleaning for the new card's video driver. 

If I got a 4090, as a matter course I'd get a PSU to match its full capability, especially considering for that level of monetary buy-in l don't want to leave any of that gcard's power unexploited, and that's coming from an owner of a 850w PSU...hence my above post.

Seeing performance issues, I wiped my SSDs and came back with fresh software. But that's not it. I have opened a ticket with Nvidia and they confirm that I don't need the 4th connector if I don't have OC.

Did you at least benchmark the system with the gpu and crosscheck to ensure the benchmark results are in line with expectations ?

3dmark perhaps ?

just to make sure that the gpu is working properly and the issue is not the hardware itself ?

[Alvega 2,126]

You guys keep talking about the GPU. It seems clear to me that his problem is the CPU, not the GPU.

I assume its the PSU, ( 1000 watt should be do it and connect all your Power cables, thats important ! ) or something could be wrong with other parts of your Hardware.. 

I also think it has nothing to do with your CPU at all.

cheers 😉

If the OP has already tried a driver sweep, then definitely what they need to do now is test their set up with another game that has benchmarks readily available with the 4090 and/or use 3D Mark TimeSpy (which is free from what I recall). As most other 'games' are less CPU intensive, by doing this, he can confirm for sure if it is likely the CPU or GPU that's underperforming. It is also possible that he could have a bad GPU.

Failing all that, a reinstall of windows might be necessary to really be sure no software is causing the issue. If it still acts up, I'd try the old GPU again to confirm everything is working as expected with that (to rule out a CPU or any other non-GPU related issue that may have coincidently happened during the transition to the new GPU even if unlikely).

It's a real head scratcher. And as @pmplayer wrote above, if may very well be the PSU. On a scale of likelihood, that's probably the most likely.

Put MSFS aside, do you have any other games where you can run the internal benchmark and compare it against the many YouTube videos that are now starting to appear.

for example assassins creed games, shadow of the tomb raider, F1 2022 etc etc

id also run 3D mark, as a couple others have suggested too

 

Can you get back to us with those results, it will prove if you have a hardware fault or setup issue with your rig. If your card runs other AAA games on a par with your peers on YT then we can turn our attention to MSFS

I just did AI Overclocking and it has reached 5.3Mhz. Same test, same result. By the way, I'm on SU11 Beta with DLSS 3.0 and Nvidia 522.25 driver and also DX12 beta with DLSS enabled in MSFS.

 

Have you tried running in DX11, just for comparison? SU11 is in Beta, as is DX12, and I've seen some reports on performance issues with DX12 and SU11 Beta. Normally DX12 should help reduce the CPU load, but there might be issues in certain situations with SU11. 

Also try to run 3DMark - in the Time Spy Extreme, a 4090 should get you a GPU score at around 19000-20000. This is to confirm whether or not you have general issues with your GPU due to the PSU. The basic version is sufficient, it can be downloaded for free on Steam.

But keep in mind that MSFS is really CPU heavy. Even with my 5800X3D I run into CPU limit occasionally at big airports with terrain LOD 200, even though my GPU is a bit underpowered (looking to replace it once the full next-gen lineup is released by both AMD and Nvidia). It depends a lot on where I am, on the scenery, the add-ons used, the aircraft, the altitude, the weather, so it isn't straight-forward to benchmark consistently.

Gosh, some people on here really have a bee in their bonnet. It's nothing to do with whether he has a 4090 or 3060, the OP has a basic issue causing a huge degradation in performance, which instead of passing some kind of moral judgement on his purchasing habits, you could try to help.

[Christopher Low 5,400]

Whatever the reason for the OP's performance problems, it isn't a great start to pair a 4090 with a CPU running at only 3.5 Ghz.

[GSalden 4,701]

For everyone with disappointing performance using their 4090 :

I am prepared to exchange the card for one of my superfast 3090s. But only if you pay me $ 500 / € 500 extra ….. 🤠

No issues and high fps guaranteed…..

Windows

- version 11 Home with daily updates

- Game Mode = OFF

- Virtual memory enabled as per recommended guides

Game Mode = OFF ???

Not related to your questions, but is this the consensus nowadays? And why so?

BTW. Is there any consensus on settings in MSFS2020 anyway at all? I remember in FSX there was pretty much consensus on best general settings.
I'm still struggling to find out all the best general settings everybody agrees on, but there's so much differing information on the internet and i'm just not enough knowledgeable about modern day hard and software anymore, lol, i'm lagging behind, signs of getting older.
But serious question though.

hmm i personally wouldn't have done it but ok .. 

I personally would NEVER buy the top tier NVIDIA GPU at release. They are always insanely overpriced.
