I have been playing Witcher 3 for a month now without any problems and crashes. However, it changed recently. Playing the game - for an hour or two - I got black screen crashes. It is happening since I updated drivers to 16.3.1 (and later to 16.3.2).
I reverted to 16.3, TDRs and black screen errors are no more, gone, everything is OK again.
My card is a Gigabyte Radeon R9 380 4gb, vga bios ver. F51, not overclocked.
Please undo this step you made accidentally backward!
