I know that it falls under the recommended CPU (4th gen I5), but I was running the game no problem over the weekend with over 10 hours of gameplay. The crashing suddenly started yesterday. Upon loading my game always crashing within 5 minutes of playtime, and it usually crashes while the AI is completing their turn. No crash notification, no nothing, just a black screen. I also run a 970 gtx and 16 GB RAM. Memory usage is around 5GB in-game, so it seems to be related to CPU performance. I already have added the exception to windows defender and disabled malware and cloud protection, lowered any settings that can help performance, and rebooted. Still having the same issues. Anyone else running into crashing issues on a 2500K, since it is still a popular CPU?
