Porting Games to Linux
Releasing across multiple platforms expands the accessibility of your game to reach more players. And given recent growth in Linux gaming‘s popularity, bringing your game over to penguin territory could significantly boost your sales and revenue.
Thankfully, porting existing games built with mainstream engines like Unity and Unreal couldn‘t be much easier these days.
For example, Unity games generally work without any modifications required thanks to its abstraction layer across platforms. You can instantly target Linux by checking a box in the build settings.
Unreal also simplifies multiplatform game distribution through its per-platform Engine Modules and Render Modules. Cross-compiling shader code automatically optimizes performance and capabilities for each target OS.
When handling Linux ports in-house proves too demanding for smaller indie studios, specialized porting companies have entered the space. The Linux game porting scene owes immense gratitude to passionate teams like Ethan Lee, Ryan "Icculus" Gordon, and Aspyr Media who helped pioneer the art of porting to Linux early on.
They work closely with developers to migrate games originally created for Windows or macOS over to Linux ecosystems like SteamOS. Their expertise with bespoke game engines and intimacy of low-level Linux graphics APIs can actualize ports otherwise considered unrealistic.
