I just upgraded to an RTX3060 from an RTX2060. Now getting consistant CTD's. Sim will crash less than 100 miles into the flight. I have reinstalled the current nvidia driver. I even used DDU to uninstal the original. I've run the sim with the community folder empty using the default A320. Still crashes. Not sure what to check next. The only thing that changed was the GPU. The 2060 ran the game flawlessly. Thanks for the replies in advance.

UPDATE : I returned the GPU to NewEgg and they sent me another one, suspecting a bad GPU. I even reinstalled MSFS2020. Same thing. There's something about that GPU that MSFS2020 doesn't like. The GPU is an MSI Ventus GeForce RTX 3060 12gb gddr6 PCI Express 4.0 Ventus 2X 12G OC.

My Computer specs :

i5-11400

32g ram

600W power supply

Not sure what to tell NewEgg.Should I have them send me a non OC model, as I've read where anything overclocked can cause issues. I'm at a total loss at this time.

UPDATE 2  Put the 2060 back in and of course used DDU to clear all nvidia drivers and reinstalled. The 2060 ran perfectly as expected. Put the 3060 back in but DID NOT clear any drivers. Used the same driver for the 2060. Happy to report crash free. So I guess sometimes it's ok to just swap GPU's and leave it at that for this particular GPU upgrade.

Update 3 Back to crashing again. Gonna try and get NewEgg to issue a store credit and try the Gigabyte non OC model. Don't know what else to try

I'm betting its the power supply.

MSFS is very demanding on the GPU and system overall, a 600w PS is the very minimum recommended by nvidia for this model. I would recommend upgrading to an 850w PS. If the only thing you changed was the graphics card, and the computer crashed, the increase in power draw most likely pushed your system over the edge. Replace the power supply and my guess is your newer video card will work fine. I recommend a modular PS for ease of install. You don't need the most expensive, but do not buy the cheapest either.

* Very Important when changing out your power supply, always change out the cables too. The reason you do this is because the polarity is different between EVGA and Corsair, so swapping just the power supply could result in a bricked motherboard.

Ken, thanks for your reply. That sounds logical to me also. Deep down I was suspecting that issue exactly. Let me see if Newegg will allow me a store credit and get the non OC card. I'll try that with the existing power supply and see what happens. If it does crash again, I'll get the new power supply.

Ken, just to be clear. The computer does not crash. Just MSFS.So I now have the 850w power supply in and all is good. Of course it's running the 2060 just fine, even when I overclock it slightly. My choices for A GPU have increased now with the new power supply. I have to buy from new egg because that is where my store credit is. I do have a budget of $500 bucks. A 3060ti is available, both standard and an OC version. I have read that MSFS might have problems with an overclocked GPU from the factory. In your opinion, or anyone else that would respond here, should I stick with the standard version or go with an OC version. Thanks

You shouldn't have a problem with the factory overclock version, but if you want to save a few bucks go with the standard version. A video card makes a huge difference in MSFS so get the best one you can afford. Sorry for the late reply, I was on vacation in beautiful Hawaii. Your probably already enjoying the video card you purchased.

Found this old thread and was wondering. Jeff D, did you solve the problem? I am running into similar FRUSTRATING CTD's situation. In my case I upgraded from NVIDIA 980 to RTX 3070 ... and have nothing but problems with FS2020 and CTD's at any random time. It does work smoothly when it runs. But it is very annoying. I also wish Microsoft had a periodic autosave feature (maybe it does and I don't know about it) so that you could at least reload the program and continue flying where you were.

Please let me know how you solved the problem (short of returning to the old GPU)

Hm. 😎 And you think that you don't overwhelm Jeff with all these fine knowledge?

I mean, he's here since 2021, and I don't know how much he knows about modular psu (afaik a psu where you only install the cables that you really need, a very fine thing, but I don't own such a fine machine, but Corsair imho is a good direction, ..)

Only a few hours ago I've seen a document, where your dear mobo (and gpu) manufacturer tells you exactly what we're talkin about right now...

Let me find this document..

Ah: The manufacturers psu recommendation for the nvidia rtx 3060

650W, but as I understand this manufacturer, it also depends on your cpu. Together with an Intel i5, a 650W psu might fit,

but together with an i7 you could "fly" a little bit more. Together with an i9 you probably urgently should.. fly more than "650 hp" .

PS: I thought that I am the only one who has gathered some years here without that the post counter reaches the sky.. But 900 isn't much either, for more than 10 years. Very dear greetings.
