Capcom’s REX engine will use AI to improve performance, QA, and overall efficiency

Capcom previously clarified that it won’t use AI to generate art.

Capcom recently tackled the topic of AI and how it plans to use the technology in game development. When discussing REX, the next iteration of the RE Engine, Capcom stated that it plans to use AI to improve workflow, identify bugs, and combat lengthening development times.

Details were shared during Capcom Open Conference RE: 2026. As reported by GameBiz, programmer Satoshi Ishida shared some of the issues that Capcom faces eight years after the creation of the RE Engine. This includes larger-scale games increasing development times, and a diverse staff that has experience with different kinds of game engines.

With this, Ishida described REX as an “AI-generation game engine.”  This is in the sense that AI will be used to hasten the debugging process, improve performance, and simplify the programming process. Back in May, following the controversy stirred by the DLSS 5 demo featuring Resident Evil Requiem’s Grace Ashcroft, Capcom’s VP of game development platform and AI solutions, Shinichi Inoue said that AI is not for creating art.

The RE Engine is Capcom’s proprietary engine, and has been used to develop beloved titles like Resident Evil Requiem, Street Fighter 6, and Onimusha: Way of the Sword. REX was announced as its successor in 2023.
