Decart's Oasis Shows Neural Rendering Complements Game Engines, Not Replaces Them

In October 2024, Decart and Etched launched Oasis, a Minecraft-like demo that generates gameplay frames using a transformer-based neural network instead of a traditional physics engine. The system predicts each next frame from player inputs trained on millions of hours of footage, statistically imitating physics rather than simulating it. Early versions drew criticism for low resolution, hallucinations, and the inability to save or persist game state — fundamental limitations of having no explicit world state. Subsequent versions shifted focus away from replacing game engines, with Oasis 3 repositioning itself as an interactive world model for robotics and autonomous systems training. Analysts note the technology is better suited to complement traditional engines — handling visuals and style — while conventional engines continue to manage state, rules, and determinism.
