It's usually pretty rare, but I'm currently getting into the late game on a huge map so it's popping up fairly frequently now. Either during the AI turns or when I try to click on a leaderhead to open diplomacy. Screen will suddenly go to black and this message appears: Display device has failed. Please ensure your display drivers are up to date. Exiting. Then I'm back at my desktop. I'm pretty sure my display drivers are up to date. This only started since R & F but it's usually pretty rare. No mods or crazy settings (Except this is one of my rare Huge map games). I use a laptop and a monitor for multi screen. My laptop screen usually running a Twitch channel and my monitor running Civ. I'm not the most technically savvy guy, but if you tell me where to look or what I need to check for I can do it. Thanks in advance.
