For those unaware, the linux version of TF2 is still 32bit, and runs on ToGL - a DirectX to OpenGL translation layer.
A few days ago, Valve published a TF2 private branch called “x64_linux_test”: https://steamdb.info/changelist/21975149/
Then a few hours ago, Valve update TF2’s “App Config” to include references to x64 Vulkan TF2: https://steamdb.info/changelist/22010846/
Looks like it’s coming soon, in theory should bring some nice performance improvements. But “soon” in Valve Time is… who knows
Edit: the beta is live
Update: the 64bit_linux_test branch is now public! Go test it! It can’t connect to public servers yet, but it’s there.
To opt in, right click on TF2 in your Steam library, then go to properties -> betas -> select x64_linux_test from the dropdown.
Some people are reporting a 25%-30% FPS increase, which is just crazy.
Does anyone have more insight why it doesn’t work with public servers? I would think that the network protocol should be unaffected by these changes.
Valve probably intentionally disabled it, just to be cautious. I think all of the other beta branches are that way too.
