What actually drives Team Fortress 2 memory use

The Source engine holds one map at a time and clears state between rounds, so usage is stable and low. What does add up is custom content: community map rotations, custom sounds and cosmetic assets all get loaded, and a heavily customised server can use noticeably more than a stock one.

The mistake to avoid

Sizing for the player slots rather than the map rotation. Thirty-two players on stock maps is cheap; a custom map pack with large downloads is what actually raises the requirement.
