That includes posts generated by LLMs. It doesn’t matter if you “don’t have the time” or “would’ve written the same anyway”, or if “everyone’s doing it geez get with the times”.
For now it’ll also include “AI”-assisted projects that haven't had at least two months of (public, verifiable) dev time behind them.

There's not really a performance penalty for Proton. It isn't an emulator (Wine Is Not An Emulator); rather it's a translation layer. It translates the machine code into something your system understands and runs it natively. It isn't creating a fake version of the hardware that runs it, like an emulator does. In fact, Proton sometimes has a performance increase because of the translation. It translates to Vulkan, which is often more performant.
