2.0.6 release, 2026-10-07: VFG real-time submission optimization, NR-first output preservation through FSR, and Blackmagic/DeckLink capture compatibility with driver properties. Full release notes.

VFG measurements: RTX 5070, GTA 4K30, original single-layer internal 1080p NR, actual Normal priority: adjacent comparisons improved Medium 4X submission readings 80→120fps (+50%), High 2X 35.5→60fps (+69%). These are local software submission measurements, not universal GPU or display-latency gains. Medium 6X+ and High 3X+ remain limited; NVIDIA VRAM growth remains unresolved. Actual AMD inference/consoles and physical Blackmagic hardware need further verification. Conditions and limits.

Highlights

2.0.4 NR controls: each NR layer's Enhancement delta → Total strength now reaches 5. Picture control defaults off; enable it and select Automatic or Manual. Automatic values now adapt separately to styles 0/1/2, with an amount slider (0 retains raw strength, 1 applies full correction). The nine manual controls cover hue, chroma, neutral tint, source color retention, lightness retention, shadows, highlights, local compression and temporal stability. Use this style’s automatic values provides a manual starting point. Switching modes keeps manual values; turning control off preserves the original residual algorithm. Five extrapolates one inference's residual, and protection reduces the corresponding changes; it cannot promise full gain five with no artifacts on every video. Presets, List/Node sessions, PNGs and video exports share the settings. Local validation and known limits.

• Rebuilt interface: Home, Cinema, Professional List, Nodes, Colour, Export and Settings; Simplified/Traditional Chinese, English and Japanese.
• Node editing and layered NR: executable connections, independent NR/colour parameters, separate List/Node configurations, sessions and presets.
• PC / Xbox streaming: Moonlight/Sunshine-compatible PC streaming and unofficial experimental Xbox support, alongside PS5, capture cards and screen capture.
• New export workflow: editable ordered queue, trimming, MP4/MKV, multiple audio/embedded subtitle tracks, cancellation/retry and completion sound.
• Enhancement and compatibility: four NR runtime choices (NVIDIA original for RTX 50, Lecram, SF-v2 and AMD lmxxf), DLSS/XeSS/FSR options, capture improvements and a persistent OBS Game Capture switch with restart confirmation. Full details are in the Release.

New in 2.0.6

• VFG real-time submission: bounded asynchronous SDK work keeps presentation moving, with per-frame success checks and ordered teardown; exports retain synchronous SDK verdicts.
• AMD NR→FSR: preserve the NR result through upscaling and first-frame/discontinuity fallback instead of reading the original image.
• Blackmagic/DeckLink: WDM upstream connection, native HDYC/BT709, driver/input property pages, exact format restoration and sustained-black observations. Physical hardware still needs verification.
• Community: switch to group 5; retain WeChat donation, Discord and Ko-fi.

Install and upgrade

Download Veyra-2.0.6-NVIDIA-win64-portable.zip or Veyra-2.0.6-AMD-win64-portable.zip for Veyra's active GPU. Extract with Windows or 7-Zip into a new writable folder and run veyra_qml_ui.exe. You need one GPU package to run the application; source assets are only for rebuilding. Windows 11 x64 and DirectX 12 are required; Qt and approved runtimes are included, while GPU/capture drivers are installed separately. Backend hardware requirements vary; most local tests used an RTX 5070.

Start with effects off, check picture/sound, then enable effects individually. High resolution, layered NR and frame generation increase GPU/VRAM requirements.

The 1.4.4 UI guide is obsolete. Version 2.0 uses separate settings. Retain the old version for rollback; do not overwrite the new package with old veyra.ini, an entire runtime_local folder or mixed DLLs.

Using 2.0

Sources and pages

Home offers files, capture card, PS5, PC, Xbox and screen capture. Files/images can also be dropped into the window. Move to the bottom edge to reveal navigation between Home, Cinema, Professional, Colour, Export and Settings.

• Cinema prioritises the picture with a floating source/transport/audio/fullscreen bar, optionally hidden in settings.
• Professional List has Picture, Frame generation, Colour, Sound and Display tabs. The order strip locates effects; bottom panels report source/output, GPU stage time and load.
• Click a file's picture to pause/resume; left/right arrows seek five seconds. Double-click or use the fullscreen button. The fullscreen top-edge bar switches Cinema/Professional; Home opens quick controls in fullscreen List mode, Ctrl+L locks controls. Shortcuts are configurable.
• Use Screenshot and the preset menu to save pictures and personal settings. No imposed built-in quality presets.

List mode

The NR version selector offers RTX 50 · NVIDIA original, RTX 50 · Lecram, RTX 20–50 · SF-v2 and RX9000 · lmxxf (experimental) in both List and Node mode. Unsupported versions remain visible but gray; switching supported versions updates the entire NR chain. AMD NR requires driver HIP 7. Video export uses at most internal 1080p inference and composites to the original output size; this is not native 4K NR and actual AMD offline encoding still needs hardware retesting. Image exports retain the native model pixel budget; HDR NR is unavailable. See runtime identities.

Select List at the top of Professional. Enable SR, NR or RTX Video HDR as needed. Up to four NR layers have independent internal resolution, strength and parameters. The master switch disables all layers and restores their previous enabled states.

List mode's global NR protection region excludes every NR layer inside it while retaining non-NR effects, useful for HUDs/subtitles. Colour controls include basic adjustments, curves, mixer, wheels, LUTs and colour presets.

Choose a supported FG backend/multiplier and check cadence, display sync, low-queue mode and output cap. Original/enhanced comparison temporarily pauses FG; leaving it resumes FG. Submitted FPS is not physical display FPS or end-to-end latency.

Node mode — build a processing chain

Select Nodes at the top of Professional. This is an executable chain editor:

1. Keep a valid connected path from input to output. Right-click blank canvas or choose Add node.
2. Drag an output port to an input port, or click the two ports in order. Drop a node on a wire to insert; drag it away or release with Alt held to disconnect.
3. Edit parameters inside nodes. NR/colour nodes have independent settings and supported positions before/after SR. Right-click to delete, duplicate or reset. A duplicate is an independent disconnected copy until connected.
4. Middle-drag to pan, wheel to zoom. Fit/auto-layout organise the graph. “Draft not running” means invalid/disconnected edits, not that every visible node executes.
5. Optical flow is shared after input; SR is a single instance. RTX Video HDR stays before final FG; select one DLSS/XeSS/FSR backend. This is not an arbitrary branching/mixing graph.
6. List and Node settings, presets and sessions are separate. Returning to List restores its settings and retains the node graph. Switching rebuilds processing and may briefly pause the picture.

2.0.6 Node mode does not support offline export or List mode's global NR protection region. Switch to List and verify its effects before exporting; graphs are not silently converted.

Capture and streaming

Pausing capture/streaming freezes the preview while keeping the session, not the host game. Physical hardware, networks, HDR and controllers need individual validation.

Export

Use List mode, confirm effects, then open Export. Add/reorder files, edit individual jobs, trim, select MP4/MKV and encoding quality, and keep all or selected audio/subtitle tracks.

Keep all skips unsupported tracks with a notice; explicitly choosing an incompatible track is an error. Pause/cancel/retry and completion sound are available. Defaults are VBR 8 Mbps and closing playback on export to free GPU resources, both adjustable. Live FG does not imply every backend supports offline FG; follow accepted export settings.

OBS and settings

For OBS Game Capture, enable Settings → General & appearance → OBS Game Capture compatibility. Saved immediately: Yes restarts now; No applies next launch. Finish exports before restarting. Software UI rendering simplifies some shadows/blur; video enhancement stays on GPU. Game Capture targets video; use Windows 10 (1903+) Window Capture for the whole UI.

Settings → General & appearance → Resume last source at startup is opt-in. It restores the movie position or saved capture device, format, rate and audio selection. Startup page is configurable. Use the playback-speed button in Cinema or Professional for 1× / 1.5× / 2× / 3×; this does not speed up live capture/streams or offline exports.

Monitoring compatibility defaults to Auto: when RTSS (MSI Afterburner OSD) is running at launch, the interface uses software rendering and its OSD appears on the video only. If RTSS starts later, restart Veyra when prompted. Using RTSS with OBS Game Capture requires RTSS’s “Use Microsoft Detours API hooking” option for Veyra, or use OBS Window Capture.

Settings include language/scale, shortcuts, monitoring GPU, audio devices and component info. Report GPU/driver, media, effects, time and logs/veyra-qml.log; include a crash .dmp if available. Review private data before sharing.

Limitations

RTSS compatibility was verified locally with RTSS 7.3.7 on an RTX 5070; GamePP and other overlay/hardware combinations remain unverified. Real-console Xbox long runs and console/VRR capture still need field retesting. RTX 30/40 community NR/FG, FSR 4 ML hardware, some NR TDR/VRAM-growth reports and cross-device streaming retain unresolved/unverified cases. See the Release. Community runtimes are not vendor certification or a complete official DLSS 5 integration.

QML renders UI; native D3D12 renders video. List/Nodes share the engine, disconnected drafts do not execute, and export does not record the preview window.
