I see you all over this thread and I want to share something you might find interesting.

You keep mentioning the server can’t handle the anti cheat because it needs to trust client data. Here’s an interesting thought: how is client anti cheat supposed to work when it needs to trust input data?

Look up direct memory access cheats. TL;DR Two computers are hooked up such that PC 1 runs the game, PC 2 reads memory from PC 1, and can then output keyboard/mouse inputs, as well as wallhacks/esp. How is the client side anti cheat supposed to know that the keyboard and mouse inputs are legitimate? How is the client side anti cheat to know wallhacks are being used when they are being rendered on an entirely different machine?

Lots of people, often unknowingly. If you run apt install firefox on Ubuntu, you’re getting the snap version.

Hate to break it to you, but Battleye already has proton support. Devs need to enable it. Ubisoft knows this and has done nothing.

What is PortProton doing that could increase performance? At the end of the day, won’t this tool just set up a wineprefix for your game and then launch it using wine/proton, just like other tools of this nature?
