Is there an *.dmp file in the games "temp" folder? If there ism and it is a current file, please post it to the bug report forum.
For the game to suddenly act differently, while we have not done anything on our end, means something has changed on your computer. That is just logical.
Are you using any anti-xxxx programs? There are a few out there which will, eventually, interfere with the game.
Other games, can also interfere with other games if they install system files. Just FYI on that one.
By the way, it remains to be seen if a restore in Windows 10 will actually roll back a driver, if Windows 10 has installed the new driver.
