Hope more people up vote this. Microsoft washed their hands of it.
Thank you for contacting Microsoft Flight Simulator Support today.
Unfortunately, we do not have any further troubleshooting steps for this issue since the error message is still indicating that the issue is caused by your GPU and/or GPU drivers.
Last thing we can recommend is to join Sim Update 3 and see if the situation has improved.
