Capcom Releases RE:Dox Library as Open Source, Benchmarks Cite 2.84x Speedup
Capcom is giving away the data layer that large-scale RE ENGINE titles depend on, which lowers the odds that the tooling it needs is gated behind its own closed pipeline.
Reporting from 1 source: Automaton.
Capcom released RE:Dox, a .NET token-based structured data library, on GitHub under the Apache-2.0 license on October 2, timed to the CAPCOM Open Conference RE:2026. It is described as one of the foundational technologies of REX, the staged next-generation project for RE ENGINE. Benchmarks shown deserialize JSON up to about 2.84 times faster than .NET's System.Text.Json, with results varying by data shape, environment, and CPU.
The release ran alongside the opening lecture of Capcom's CAPCOM Open Conference RE:2026, which set out the outlook and future of REX, the staged upgrade of the company's in-house engine. RE:Dox is a token-based structured data engine for .NET, and the published repository includes sample code for player data: converting a level 42 Leon with a handgun and a green herb into JSON, then reading it back to rename the character Claire and add a knife to the inventory. Capcom puts the library under Apache-2.0, which permits commercial use and modification under the license's conditions.
