It's a ue4 based game project. Unsure of the size offhand, sorry (and it's Sunday, so I'll check tomorrow).

Nope. We just use the same machines for the same jobs (we have 3 agents, and we use teamcity which lets us pin our configurations to agents), and incremental builds. Really basic stuff. The machines are managed by terraform and packer and we rebuild the images once a month or so, so semi frequently pay the full compile hit. I am going to look into actual persistent caching for Mac very soon, it's likely we'll go with fastbuild!
