Important
QuickFury has been superseded by FuryPlusPlus.
FuryPlusPlus ports all 21 of QuickFury's validated speed patches and adds output-quality passes
(fewer animator layers, fewer synced parameter bits). QuickFury is no longer maintained and its
releases have been withdrawn. To migrate, remove com.quickfury.addon and install FuryPlusPlus —
the two must never run together, and settings do not carry over.
QuickFury is an Editor-only, bolt-on performance layer for an existing VRCFury installation. It profiles VRCFury avatar bakes and replaces measured hot paths with indexed implementations. It does not ship, fork, or modify VRCFury.
Version 1.1 was a complete rewrite. Its initial benchmark reduced a warm VRCFury bake from 98.542 seconds to 23.810 seconds (75.8%). The subsequent 1.2 optimization pass reached a best clean measurement of 13.996 seconds.
| Component | Base VRCFury | QuickFury 1.1 | QuickFury 1.2 |
|---|---|---|---|
| Full VRCFury bake | 98.542 s (1.00x) | 23.810 s (4.14x faster) | 13.996 s (7.04x faster) |
| Armature Link | 61.762 s (1.00x) | 6.467 s (9.55x faster) | 1.255 s (49.21x faster) |
| Controller layer lookup | 11.844 s (1.00x) | 0.572 s (20.71x faster) | 0.572 s* (20.71x faster) |
| Deferred animation-path rewrite | ~2.270 s (1.00x) | ~0.140 s (16.21x faster) | ~0.140 s* (16.21x faster) |
| PhysBone removal | 6.228 s (1.00x) | — | 0.120–0.170 s (36.64–51.90x faster) |
| SaveAssets | 14.554 s (1.00x) | 6.365 s (2.29x faster) | 2.284 s (6.37x faster) |
Speedups in the table are relative to the original Base VRCFury measurement. The 1.2 column was captured in a later profiling session; its same-session control was 31.947 seconds overall, 7.901 seconds for Armature Link, and 7.008 seconds for SaveAssets. These measurements come from one large avatar and one machine, not universal performance claims. Asterisks mark unchanged 1.1 optimizations whose isolated measurement was carried forward; components without a meaningful measured reduction are omitted.
The benchmark avatar is an intentionally extreme, worst-case stress test. The current loaded source avatar contains inactive outfits and build-time content because VRCFury still has to inspect and transform that data during a bake.
| Source-avatar metric | Count |
|---|---|
| Hierarchy objects | 8,955 |
| Components | 9,497 |
| Rendered mesh instances | 54 (38 skinned + 16 static) |
| Unique meshes | 42 |
| Rendered geometry | 232,504 vertices / 359,523 triangles |
| Blendshape channels | 767 |
| Distinct transforms referenced as skin bones | 8,484 |
| Materials | 44 unique / 73 renderer slots |
| Source animation setup | 76 clips / 3 controllers / 33 layers / 73 states |
| Controller parameters | 78 |
| VRCFury content | 89 features + 13 haptic sockets |
| Major VRCFury features | 37 toggles / 32 Armature Links / 5 full-controller imports |
| PhysBones | 81 PhysBones / 60 colliders |
| Contacts | 7 senders / 40 receivers |
| Constraints | 36 |
These are live source-scene counts from the current benchmark avatar. The avatar evolved during development, so an older historical run may differ slightly from this snapshot.
This avatar represents a worst-case workload; a more typical avatar should generally complete its bake faster in absolute terms, although the relative speedup depends on which VRCFury features it uses. Eventually the limiting factor also stops being VRCFury's managed code and becomes the machine, Unity's native asset and serialization work, or other Editor systems.
I was satisfied with the current speedup-to-work ratio after capturing the major low-hanging bottlenecks. Further speedups are probably possible, but they increasingly require replacing larger portions of VRCFury's underlying systems and working around—or effectively substituting for—more Unity-side behavior. At that point substantially more engineering work produces progressively smaller gains. Further updates will probably focus on cleaning and slimming down the code.
QuickFury is an unofficial third-party addon. It is not supported, endorsed, or maintained by VRCFury, and it modifies VRCFury's Editor-time behavior through internal patches. Issues may occur, and the project provides no guarantee that every avatar, Unity project, or future VRCFury release will work correctly.
Do not report a problem to the VRCFury project while QuickFury is installed. First remove QuickFury completely, let Unity recompile, and reproduce the problem using stock VRCFury. If the problem occurs only with QuickFury installed, it is a QuickFury issue and should be reported to this project instead. QuickFury is provided without warranty; use it at your own risk.
- Unity 2022.3
- VRChat Avatars SDK 3.10.3 or newer
- VRCFury installed separately
- Behavior-changing optimizations: VRCFury 1.1363.0 exactly
QuickFury resolves VRCFury's internal Editor methods at load time. Profiling remains available when its signatures match, but all behavior-changing patches fail closed on unknown VRCFury versions or unexpected method signatures.
Install VRCFury normally first. Then add com.quickfury.addon/package.json through Unity's
Package Manager. A local manifest entry looks like this:
"com.quickfury.addon": "file:C:/path/to/QuickFury/com.quickfury.addon"After compilation, the Console should report:
[QuickFury] Ready for VRCFury 1.1363.0 (...).
Controls and profiling reports are under Tools > QuickFury. Removing the QuickFury package and recompiling restores stock VRCFury behavior.
- Armature Link constraint, PhysBone, skin, and destruction queries
- Controller layer-to-tree lookups
- Ordered deferred animation-path rewriting
- Empty deferred-rewrite passes
- Generated-asset saving through Unity 2022 asset-editing batching
- Armature Link object moves and optional debug-component creation
- Generated controller-asset discovery, traversal, and storage
- Controller parameter, tracking-behaviour, and behaviour-container lookups
- Blendshape binding and SPS material/renderer probes
- Exact deduplication of redundant generated animation clips
The package includes exact per-action timing on every bake and optional detailed internal timings. See the package README for controls and safety details, and the performance report for methodology and validation.
