In the time since Quake released, common rendering systems and resolution options on monitors have changed. ID’s solution to put it back on Steam was some gargantuan monolith wrapper that might’ve used Unity or something, and ties to an online ID, so that it could release on consoles. The open source community’s solution was to take the original, open-source engine release, and port it upwards. Playing through the recent Quake Brutalist Jam 3, a map pack using a set of reinvented weapons and altered enemies, they recommend you use the “ironwail” source port, which even has a native Linux build.
