I was able to play Fallout 4 without any problems for 20+ hours, but suddenly today I have started experiencing CTD's with no errors after playing for about 10 minutes. Whenever the game crashed to desktop, windows gave me a "Display driver has stopped responding and has successfully recovered" error, that led me to suspect a faulty display driver, I did some research on internet and settled on installing the 15.11 Beta drivers since it apparently helped some people with their crashes with fallout 4. Just to be sure I did a fresh install on the drivers, clearing the registry etc. It didn't work, the game still kept on crashing. I decided to reroll drivers to latest proper release and that was no dice as well.
Here's my system specifications.
GPU: AMD R9 380 4GB
Memory: 8GB
CPU: i5 3450
OP: Windows 10 64 Bit
