Garage Collective explains the technical approach behind DrakkenRidge, an open-world action RPG designed for mobile VR. Its two-person team uses Unity’s Entity Component System to make large visible environments practical within a headset’s performance budget.
The article describes moving most world rendering to entities while keeping many close-range interactions in conventional GameObjects and MonoBehaviours. Shared meshes, texture atlases and materials allow Entities Graphics to batch substantial parts of the scene, reducing the overhead of evaluating separate object hierarchies.
A custom distance-authoring system determines when objects should disappear, share decisions or switch to cheaper representations. Its calculations use Burst-compiled jobs. That lets distant terrain and objects remain visible while reducing work on details that no longer require their most expensive form.
Physics-driven climbing and combat stay important to the player’s immediate interactions, so the project combines systems rather than replacing everything with ECS. The developers also describe the learning curve and integration cost of that choice. Their example demonstrates an architecture tailored to this game, not a rule that every VR project should migrate wholesale.
