Freezes every 10 seconds

Every 10 seconds the game freezes for a few seconds. I’ve seen lots of complaints about lag in team games but this is happening when I try and play the campaigns. Seriously why is this happening? I used to be able to play them fine and my PC should be more than good enough to run Age of Empires. Lords of the West might seem cool but what’s the point when even singleplayer is unplayable?

Happens for me too (Barbarossa campaign and the Khmer campaign I think), just less frequently than this
