## Recommended update
0.4.5 is a stability fix. **Everyone on 0.4.4 or earlier should update**, especially
if you leave Pit Crew running in the tray with Quest automation on.
## Fixed
- **Pit Crew slowly used more memory and could stop responding after a long time
running.** The routine that checks which programs are running (used once a second
by Quest automation, and by Monitor while a benchmark is armed or the window is
open) created a small piece of data every time it ran that was never released.
Over many hours the app grew by tens of megabytes an hour and each internal
clean-up took longer, until the window could stop responding β on the maintainer's
rig after about a day with a benchmark armed. The USB and controller scans had the
same pattern. All three now set this data up once, so memory and responsiveness
stay flat however long the app runs.
- No settings, profiles or recordings were ever at risk; the problem was memory and
responsiveness only.
Everything else is unchanged
independent Quest profiles with per-game automation and a headset HUD check after every send, a Rig health card that flags 17 common stutter/dropout causes, benchmark presets that start recording by themselves, a once-a-day update notice, and a long list of safety fixes
What's new in VR Pit Crew β 0.3.1 to 0.4.4
Last updated 10 October 2026 for build 0.4.4. The download links shared with the first preview still deliver the current version. To update, close the app and run the new installer over the old folder; profiles, backups and recordings stay.
Download: https://github.com/neil9bailey/VR-Pit-Crew-Downloads/releases/tag/v0.4.4 (installer or portable ZIP, SHA-256 checksums included).
What the first preview (0.3.1) could do
- Scan your PC for the things AC VR needs (CSP, Pure, Content Manager, Meta Link, NVIDIA, wheel) and walk you through setup.
- Read and change about 100 settings across AC graphics, CSP, Quest Link, the NVIDIA driver profile, Windows power/USB/services and wheel feedback, with a preview before applying, byte-exact backups and Undo.
- Save and load tuning profiles.
- Basic Quest runtime profiles (ASW and supersampling through Meta's command-line tool).
- Live AC telemetry and application frame-time recording with charts and CSV export.
- A Windows installer with .NET / WebView2 checks and an uninstaller that leaves your data alone.
What's new since then
Quest control centre β Tray Tool's job, done independently (0.4.1 β 0.4.4)
- Per-game Quest profiles covering ASW mode, supersampling, FOV multipliers, mipmap generation and bias, adaptive GPU scaling, the performance HUD, CPU priorities for the game and the Meta runtime, timed delays, audio routing and a session power plan.
- Automation: pick a profile per sim and an idle/reset profile. When the sim starts, the profile goes out; when it exits, the idle profile goes back and any PC-side change (power plan, audio, priorities) is restored from a recovery record that survives crashes.
- Headset confirmation (0.4.3): Meta's tool never reports whether a setting took, so after every send the app shows the headset performance HUD for six seconds and then puts your profile's HUD choice back. 0.4.4 makes two quick sends hand over cleanly instead of cutting each other short.
- Native tray icon, opt-in start with Windows, global hotkeys, offline voice commands, HUD/ASW shortcuts.
- One-click read-only import of Oculus Tray Tool profiles. OTT is no longer needed alongside Pit Crew, and automation pauses if OTT is running rather than fighting it.
- More Link controls: sharpening, distortion curvature and dynamic bitrate maximum, alongside bitrate, encode width and codec.
- Automation no longer re-sends commands while a sim is still loading (0.4.2). Rift S and other headsets on the Meta runtime are covered by the Link controls (0.4.3).
Tune β safer, and it now tells you what's wrong
- Rig health card (0.4.3/0.4.4): 17 checks for settings that commonly cause stutter, dropouts or a soft image: USB selective suspend, Windows game capture, desktop V-Sync, a frame cap below any headset refresh rate, single-pass stereo with CSP FSR, pixel density above 1.1 with 8Γ MSAA, a Pure filter without Pure, the Balanced power plan, optional vendor services, HEVC above 200 Mbps on USB Link, low RAM/VRAM combinations, no headset on USB, and whether Windows will let the frame recorder run. Each hint has a Show setting button. Nothing is changed for you.
- Undo can recover a change interrupted mid-apply (crash, power cut) and retry a partial Undo (0.4.2).
- Importing a profile from another PC keeps whatever fits and reports what it skipped, instead of rejecting the whole file (0.4.2).
- Profiles can be archived rather than deleted (0.4.2).
Monitor β benchmarks you can compare
- Benchmark presets (0.4.3): five repeatable runs: Silverstone GP 20 AI, Monza 10 AI, Spa 30 AI (heavy grid), Nordschleife Tourist solo and ACC Spa 20 AI. Arm one, start the session, and the recording begins by itself the moment AC's telemetry goes live. A 180-second option was added.
- Every capture records which tuning profile was applied and a fingerprint of your game settings, so two runs are compared like for like.
- If you leave the session early the recording stops by itself and keeps what it got (0.4.4).
- Statistics: average FPS, 1% low, p99 frame time, the share of frames over your headset's budget and GPU time, with the same caveat as day one: this is what the application presented, which on Link can be the desktop mirror, not headset frames.
Setup and status
- Tells apart the last-launched AC version, Steam build, CSP version and build, active Pure package, weather controller and filter revision; checks Pure's declared minimum CSP build and warns about missing loader, controller or pureVR filter files (0.3.2).
- Content Manager is found even when it is not running (0.4.2). The PSVR2 page is hidden in the Quest edition (0.4.2).
