DLSS 5 Studio v2.0.3 ⚡

Neural Rendering deployment gating, interactive Streamline guidance with RenoDX Discord access, Cloudflare R2 add-on CDN distribution, and Skynizz v1.2.1 DLSS 5 OptiScaler integration.

---

🧠 Neural Rendering & Streamline Deployment Gating

• Proactive Model Verification & Deployment Gating:
  • Enforced strict deployment gating across all routes (OptiScaler, Native ReShade, and Feeder): deployment will not proceed if the Neural Rendering runtime (nvngx_dlssnr.dll) is missing from components/streamline/.
  • The Game Detail "Deploy" button proactively checks cache status and brings up the guidance modal directly, preventing broken in-game injections.
• Streamline Guidance Modal & RenoDX Discord Integration:
  • Interactive modal providing clear instructions on completing the Streamline setup.
  • Direct inline link to the RenoDX Discord server to obtain the modded Neural Rendering runtime for RTX 20/30/40 cards.
  • Added a dynamic "Verify & Refresh" button that validates is_streamline_complete() on demand and automatically dismisses the modal with a confirmation toast once the model is detected.
  • Includes a "Manual Open Folder" button directly opening the components/streamline/ directory in Windows Explorer.
• Visual Add-on Cache Status Badging:
  • The Add-ons page Streamline card now displays a prominent yellow ⚠ Incomplete badge if base Streamline SDK files are cached but nvngx_dlssnr.dll is missing.
• Detached URL Launcher (Freeze Fix):
  • External links now spawn in a detached background worker thread using Win32 CREATE_NO_WINDOW (0x08000000), completely resolving UI freezes when users close external browser windows.

🔄 Priority-Based RenoDX Engine & Authentic PE Header Versioning

• Priority-Based Add-on Resolution:
  • Runtime component discovery prioritizes modern renodx-dlss.addon64 (Priority 1) while seamlessly retaining backward compatibility with legacy renodx-dlss5.addon64 (Priority 2 fallback) for existing installations.
  • Automatically purges conflicting alternate add-on files in the target game directory upon deployment to ensure ReShade does not attempt dual hooks.
• Authentic PE Version Inspection & In-App Updates:
  • Inspects actual PE file headers directly from .addon64 binaries (detecting v0.2026.0827.2036 on legacy files vs v0.2026.1016.1704 on modern builds) rather than relying on stale "latest" entries in the manifest.
  • Older installations immediately show the v0.2026.0827.2036 → v0.2026.1016.1704 upgrade path with a one-click [ Update to v0.2026.1016.1704 ] button in Settings > Add-ons.
  • Directly resolves and downloads renodx-dlss.addon64 (~3.2 MB) from high-speed Cloudflare R2 storage without GitHub API latency or rate limits.

⚡ OptiScaler DLSS 5 v1.2.1 & Pre-SR Enhancements

• Skynizz OptiScaler DLSS 5 v1.2.1 Integration:
  • Upgraded built-in OptiScaler component catalog to Skynizz's v1.2.1 release featuring advanced Neural Reconstruction INI tuning, luminance stability (CacheLowTemporal), and x8 performance presets.
  • Direct Feature 18 parameter forwarding and robust proxy hooking.
• Dynamic Add-on Version Discovery:
  • Eliminated hardcoded addon version tables in favor of dynamic runtime inspection and self-healing directory unwrapping.

---

🌐 Cloudflare R2 Add-on CDN Distribution

• High-Speed CDN Distribution:
  • Migrated add-on asset hosting to dedicated Cloudflare R2 CDN storage (pub-fc0eb49bf297443d8eb1e209c15135fe.r2.dev) for faster, rate-limit-free worldwide downloads.
  • Maintained automated fallback resolvers across all component downloaders to guarantee resilient multi-source asset acquisition.

---

🛡️ Journal Parity & Vanilla Backup Continuity

• Cryptographic File Parity & Snapshot Preservation:
  • Preserves genuine unmodded vanilla backups through successive cross-route swaps without requiring an intermediate restore.
  • Guaranteed clean uninstall and rollback with 100% byte-for-byte file parity, preventing mod proxies from corrupting backup directories.

📜 Previous Releases

DLSS 5 Studio v2.0.2 — Sunshine / Apollo Streaming Lifecycle & Smooth Big Picture Transitions

• Sunshine / Apollo Stream Lifecycle Management:
  • Registered DLSS Studio in apps.json with canonical Sunshine options (auto-detach: false, wait-all: false, exit-timeout: 5).
  • Resolves an issue where exiting Big Picture left the Moonlight stream hanging on a frozen screen. Sunshine now detects process exit immediately, terminates the stream, destroys the virtual display, and returns Moonlight to the client menu.
• Dual-Event Streaming Process Bridge:
  • Spawning a secondary instance via --big-picture signals the running desktop window to switch to Big Picture mode and holds the stream session until exit without single-instance mutex collisions.
  • Monitors both the stream exit event and desktop process lifecycle with zero CPU polling via Win32 WaitForMultipleObjects.
• Smooth Enter & Exit Transitions:
  • Added dedicated blackout transition screens (bp_entering_title, bp_exiting_title localized across all 14 supported languages) to conceal desktop window repositioning and virtual display switching.
  • Cleaned and reset launch overlay signals on desktop return to prevent freezes.
• Refined Exit Confirmation Dialog:
  • Simplified the Big Picture exit modal to two distinct action buttons (Exit Big Picture / Cancel).
• Core Domain Modularization:
  • Restructured monolithic core architecture into 18 dedicated submodules (routes/, advisories/, payloads/, scan/, steamart/, journal/, addons/, platform/, vibepollo/, utils/) for clean domain separation and improved maintainability.
• In-Process Setup Extraction:
  • Replaced external process invocations during setup extraction with in-process Win32 registry and process APIs for instantaneous payload unbundling.

• DirectX 11 OptiScaler D3D11on12 Interop & Streamline 2.14.1 Stack:
  • Robust first-class DirectX 11 OptiScaler support bridging DX11 DLSS calls through D3D11on12 to modern DLSS 5 Neural Rendering.
  • Deploys verified Streamline 2.14.1 stack into OptiScaler/streamline/ and nvngx_dlssg.dll to root on DX11 titles, permanently eliminating DXGI_ERROR_DEVICE_REMOVED crashes.
  • Injected non-blocking blue configuration notice (AdvisorySeverity::Info) alerting users that DirectX 11 Multi-Frame Generation operates via D3D11on12 and requires an in-game DLSS setting.
• Cumulative Injected History (added_history.json) & Backup Continuity:
  • Introduced cumulative added_history.json tracking immune to 5-manifest rollback pruning, guaranteeing 100% clean restoration with zero orphan DLLs.
  • Carries forward genuine unmodded vanilla backups through successive route hot-swaps without intermediate restore.
• Scanner Accuracy & Vulkan Gating:
  • Gated Vulkan titles from reporting false positive Frame Generation support (Unsupported (Vulkan API)).
  • Removed sl.dlss.dll from the Frame Generation heuristic.
  • Prevented mod-deployed nvngx_dlssg.dll from triggering false Native DLSS-G detection via journal verification.
  • Sandboxed test environment for vulkan_layer.rs to prevent automated test runs from modifying host registry keys.
• Dynamic Route Advisories Engine:
  • Added get_mfg_advisory_with_route evaluating active route and backend limitations across Vulkan, Feeder, and DirectX 11 with zero user lockouts.
• Multilingual Copy Refresh:
