Earlier today Valve made a new depot for TF2 called “x64_linux_test”. Maybe this mean well get a native 64 bit client ( and hopefully DXVK instead of ToGL please Valve) or this is just server stuff

Apparently all source 1 games are 32 bit. Except for CSGO…
How
engine was made when 64 bit operating systems werent mainstream yet
But that’s not possible. It has to have some kind of 64 bit binary. It uses well over 4GiB of RAM.
