The Elder Scrolls IV: Oblivion Remastered uses a combination of two engines: Unreal Engine 5 and the original Gamebryo engine. Specifically, Unreal Engine 5 is employed for the full graphics overhaul, including modern rendering techniques, ray tracing, updated textures, and models, while the Gamebryo engine handles the core gameplay mechanics, physics, and game logic. This means that the visuals are powered by Unreal Engine 5, but the gameplay systems remain rooted in the original engine from the 2006 game
. This hybrid approach allows the remaster to look like a modern remake visually, but it still plays like the classic Oblivion, maintaining the original game's structure and mechanics. The developers describe the Gamebryo engine as the "brain" driving gameplay, with Unreal Engine 5 serving as the "body" that brings the experience to life with updated visuals
