I’ve been looking through the project structure and recent commit history, and I have a couple of questions about the current direction of ALVR’s architecture.

From what I can see, development is still active (last commit ~9h ago), but several core features are still missing or incomplete even after months of updates. At the same time, there’s a cpp-refactor branch that hasn’t been touched in roughly two years or more.

Given that:

ALVR already integrates with OpenXR

the cpp-refactor branch exists (even if dormant)

Rust introduces challenges for low-latency, buffer-heavy pipelines

and some basic functionality still isn’t implemented

I’m trying to understand what the long-term plan is.

Is the Rust-first architecture still the committed direction for the project, or is the team open to moving more of the pipeline back toward C++ where latency, GPU interop, and real-time behavior are easier to optimize? Or is the C++ branch simply an abandoned experiment?

I’m asking this from a technical perspective, not to criticize the project — I’m just trying to understand whether the current architecture is expected to evolve or whether Rust is the permanent foundation going forward.

Thanks for any insight you can share.
