Known issues

From ReCarbon’s reference/ROADMAP.md (M7, “Known issues for the alpha”). Each is still open.

Issue Details
Occasional stalls of about 1 s The presenter waits for a free drawable while holding the GPU queue lock. Being investigated; to revisit before a public release.
GPU-idle stalls of 250–600 ms No lock wait involved. Cause unknown.
Physical controller untested The default mapping is pinned by a test and a virtual controller reaches the menus, but no real pad has been tested yet (M5).
Release packaging links Homebrew’s libraries The bundled Vulkan loader names /opt/homebrew paths (check_app check 3). On a Mac with Homebrew, Vulkan layers installed there could be picked up. Fixed by building the libraries from source (M8).
macOS 27 or newer only Current builds link libraries built for macOS 27.0.
Movie frame pacing Movies play at the right speed, but 20–28% of frames show for 1 or 3 refreshes instead of 2. Smoothing is deferred to polish.
  • Controls on a controller and on the keyboard in a race, by hand: Throttle, Brake / Reverse and Steering; Change Camera, Look Back, gear shifts and Pause (so far seen only with the virtual controller); and where Handbrake, Nitrous and Speedbreaker are.
  • Vehicle physics against the Xbox 360 version.
  • Frame pacing over 10 minutes of racing.
  • Audio and picture during racing.
