Yep. Or downgrade, if you can find a copy of W7. Regardless that's exactly what you (and I for that matter) gotta do.

A shame, I am not looking forward to the hellscape that awaits me in W10. I have enough horrorstories of the OS from most of the people in and out of my close circle who "Upgraded".

Well, for what it's worth, I ended up doing the free upgrade to Win 10 (which is still available somehow), and that fixed the flatlining issue for me.

Because MS wants you to, you can still upgrade from Windows 7 or Windows 8 keys to Windows 10. But for me the installation of Windows 10 fails with installation from USB, so i'm doomed. :(

Hi guys. I solved my problem by reinstall nvidia driver and update everything available in Windows updates.

Ouff... Same setup as me.

Shout if you get it working! Tried it, didn't work.

Thanks for the tip anyways.

My initial crash was solved by updating the nvidia drivers to the ones realeased on the 9'th.

BUT the game still crashes after about an hour or so ... and it crashes so badly., that it takes down the entire graphics driver with it!
In fact I have to reboot the system just to get it working again. :-(

Found possible fix to launch issues, installing Microsoft Visual C++ 2015

Had cloud sync, .dll missings errors, etc

Updated windows and the game with the latest patch and it works!
