Raffaele,

There is a known problem with the latest nVidia driver. If you roll back your driver one version, then it should run OK.

Did you roll back the nVidia driver to the previous version?

Jorgen

[JackSwyr]

Doing it now. Thanks, I hope this helps. It's ridiculous that this even happens in 2021.

[JorgenSA]

nVidia screwed this one up, they are looking into it.

At first I thought it was me upgrading windows this morning to the dopey "Experience Pack: 120.2212.5510. OS Build 19042.906. Version 20H2.

I had driver 465.89 so I rolled it back to 461.92 and it still crashed.

Now I have 461.72 and the PMDG 777 is sitting on the end of the runway at YSSY.

But I KNEW I ran the sim with the drivers I mentioned about and it was fine. I'm still wondering if it's a Windows OS problem.

[JorgenSA]

No problem with the Windows update, as far as I know this was solely a nVidia driver problem.

Jorgen

[JackSwyr]

Thanks Jorgen.

Ok, I know that you are supost to roll your drive back one version, but how do you do that

Ok, I know that you are supost to roll your drive back one version, but how do you do that

Go to NVIDIA’s site and look at the older drivers.

Search the web for this:

nvidia driver rollback

or something similar.
