Rubinite Patch [0045e17] Targets Memory Leaks and Adds Graphic Quality Setting
Developer cupdoggames has shipped patch 0045e17 for Rubinite, a build that addresses several under-the-hood problems while adding one new option to the settings menu.
What changed
- New "Graphic Quality" setting under Settings → Graphics, allowing players to trade fullscreen effect render resolution for performance gains
- Performance and memory optimizations described as most noticeable in The Plaguebearer's level
- Audio pass covering Roy's Dagger dart shots, the Witch's opening name sequence, the Witch's execution, the Nun's Room memory (Act 1), and various cutscene and UI sounds
- Fixed post-processing effects breaking during certain cutscenes
- Fixed navigation order of the new Graphic Quality option in the settings menu
- Fixed enemy objects failing to release from memory after leaving a level
- Fixed every level's object pool remaining in memory from boot
- Fixed two save-related code issues on PC
The memory fixes are likely the most consequential changes here — objects persisting across levels and a full level pool sitting in RAM from boot are the kind of quiet issues that compound over a long session, and their resolution should make extended playthroughs meaningfully more stable.
