VIIPER RC1 - Release Candidate

DS4Windows VIIPER release-candidate summary

Scope: v4.0.2.3 to f1e4b32 (188 non-merge commits)

Generated: 2026-07-24

Release-candidate highlights

• DS4 Bluetooth audio and haptic transport was stabilized end-to-end, including report-rate pacing, queue ordering, credit/handle behavior, and fallback behavior to remove dropouts and stutter.
• DualSense and DualShock 4 audio/mic/haptics routing were hardened across physical + emulated output combinations.
• Audio Haptics and Trigger Lab features were implemented/improved with profile-level persistence and richer trigger controls.
• Profile UX was modernized (overview, profiles, editor, remapper, controller selection/status, and live filtering/search).
• VIIPER output support was expanded/cleaned (virtual backends, installers, lifecycle, driver handling, diagnostics).
• Game Bar compatibility and visibility handling were improved, including temporary companion and profile priority behavior.
• Updater and installer flows were tightened to prefer stable/preview intent correctly and better guide users through dependencies.
• Multiple regressions were reverted and reintroduced intentionally through transport hardening before landing on the final 0x12 transport tuning.

Focus-by-feature

1) DS4 Bluetooth audio transport and reliability

• Finalized transport behavior for reliable low-latency DualShock 4 Bluetooth speaker output and stable completion timing.
• Corrected HID report timing coupling with input cadence and removed short-report/queue instability artifacts.
• Added stronger in-order and availability checks to protect audio and input from race conditions.

2) DualSense/PlayStation audio, haptics, and mixed-routing compatibility

• Added and stabilized native DualSense speaker/mic pathways and synchronization with advanced haptics.
• Improved compatibility across emulation variants and preserved advanced output during emulated output transitions.
• Added safeguards for Bluetooth audio routes and route-matrix consistency in controller emulation modes.

3) Audio Haptics and Trigger Lab

• Introduced or updated audio-haptics capture/app routing and per-profile controls.
• Added trigger-specific lab controls (including full-pull/action routing and linked/split behavior).
• Added stronger profile persistence and editor integration for special effects data.

4) UI/UX and profile workflow

• Reworked profile editing path and overview controller workspace behavior.
• Added controller-aware remapping overlays, layout polish, and search-driven list filtering.
• Reduced editor and profile transitions stalls and made switching behavior more deterministic.

5) Compatibility and devices

• Added support and handling improvements for virtual/compatibility paths including Moonlight and companion flows.
• Preserved VIIPER lifecycle/race handling and fixed HidHide/session stability around service transitions.
• Added/cleaned installer, uninstall, and setup flows for VIIPER and virtual DualSense driver stack.
