Project Mix Demo Patch 3.5 Targets Stuttering and Performance
Project Mix Demo Patch 3.5 implements streaming audio, optimized texture resolutions, and item spawner rewrites to reduce stuttering. The update brings over optimizations learned during the Quest 3 port.
Project Mix has received Demo Patch 3.5. This optimization update applies technical improvements gathered during the Quest 3 port to smooth out performance and reduce stuttering without altering visual quality.
Performance and Stutter Reduction
Longer audio files now stream into memory to prevent stutters. The Item Spawner has been rewritten to eliminate hitching during bar loadup, and Oculus Reset View now recenters correctly.
Visual and Asset Optimizations
Background bottles in the staffroom are replaced with tailored opaque models to improve draw call performance. Developers created a custom unlit shader using average light probe colors for background elements, optimized texture resolutions to save memory, added material property blocks for flare fades, and disabled idle liquids in RTDs along with hiding particle and liquid visibility issues when pulling the reset lever.
Why this patch matters
Patch 3.5 delivers technical adjustments that clean up performance issues ahead of the demo's Meta Quest 3 launch in October.
