Fallout: New Vegas is an old game that many players report crashes regularly on their Windows PCs. For example, an FNV player’s Reddit post says this: “Fallout New Vegas crashing every few minutes or so, tried everything… Whenever I load and play for a few minutes, it just closes out of the game randomly, and it’s awful.” Some players report Fallout: New Vegas crashes when they try to start new games. This is how you can fix regular in-game Fallout: New Vegas crashing on Windows PCs.
Run Fallout: New Vegas in Compatibility Mode
