From TFA: > As [1]announced on the official TF2 website [1] https://www.teamfortress.com/post.php?id=238809 https://www.teamfortress.com/post.php?id=238809 states: > We're also doing a big update to all our multiplayer back-catalogue Source engine titles (TF2, DoD:S, HL2:DM, CS:S, and HLDM:S), adding 64-bit binary support, a scalable HUD/UI, prediction fixes, and a lot of other improvements! So that seems to be coming, at least in the sense of x86-64 which Apple Silicon supports better via Rosetta 2.
