Hi Jeremy,
From the start MSFS 2020 was unstable even in downloading it, it would crash frequently, took me about four days to completely download.
Next problem was even reaching the Options page. just kept crashing. Rather frustrating.
I had Task Manager up and noticed the GPU chart collapse just prior to a crash, which got me thinking.
This is a new computer, with the previous one slowly dying.
For some reason Windows wouldn't let me install the NVIDIA drivers. The computer worked, so I left it alone and had no issues.
However, MSFS 2020 fixed that.
I went into 'System' and verified that I had the correct driver, not the suggested one. I found it hard to compare the latest NVIDIA driver with what I had as they used different styles of version numbers. In the end, the NVIDIA one was more recent so I tried downloading it again and it installed without issue and so did my crashing issues with MSFS 2020.
It's still a bit twitchy but at least I can get into flight training.
My next issue is the yoke assembly, have some issues there. I find the keyboard controls to active and I end up losing control and crashing. Something else to fix. :)
