Changes

• Added background connection analysis with remote version information and concise recommendations.
• Higher capture FPS on macOS: continuous desktop capture avoids rebuilding the capture session for every frame. In a local Apple M4 Pro / 1080p H.264 smoke test, throughput increased from 9.38 to 57.19 FPS; configured limits of 20 and 30 FPS achieved 19.81 and 29.65 FPS. These are short local measurements, not guaranteed remote-session FPS or end-to-end latency results.
• Double Buffer streaming: capture, encoding and transmission now run as separate stages with two work slots at each handoff, allowing adjacent stages to overlap. The receiver also separates packet reception from decoding with a two-slot buffer. Buffer depth remains bounded to avoid accumulating outdated frames; Double Buffer alone is not a guarantee of lower latency.
• Added Windows GPU desktop capture with a software fallback. Windows performance gains still require real-device validation.
• Added automatic stream configuration options and proportional Remote Display window fitting.
• Added local Host startup checks and a confirmation dialog when an existing Windows Host process can be identified. These safeguards do not fully resolve the known occupancy issue.
• Renamed user-facing Viewer labels to Remote Display; added explanations for reduced FPS and traffic on a still screen.
• Improved warning visibility and cleaned up idle connections used for presence checks.
• After downloading and verifying an update, the app automatically opens the macOS disk image or Windows installer. The download location is labeled clearly; the red “Quit application” button exits the app and its managed remote sessions before installation.

Packages and validation

macOS Apple Silicon DMG and Windows x64 / ARM64 installers. macOS packages are signed and notarized. Platform builds and syntax checks completed; the duplicate Host issue remains under investigation.

YourDesk 1.26.0909 build 2206

What's new

• Added Apple low-latency frame interpolation alongside RIFE. Auto mode prefers Apple on supported Macs running macOS 26 or later; RIFE remains available on Apple Silicon with macOS 13 or later. Enhancement and interpolation still default to off.
• Improved Apple interpolation handling for larger frames, including Core ML upscaled inputs, to address processor initialization failures. Generated frames use a bounded working resolution; original frames retain their resolution. Warm-up or processing delays can still fall back to original frames.
• Expanded the macOS monitor selector into up to four numbered buttons in the center of the toolbar, with separators on both sides and a green outline for the active display.
• Fixed macOS toolbar click handling, including display buttons covered by the drag area and tooltips consuming the first click.
• Improved bidirectional clipboard synchronization and retry handling. Mac-to-Mac clipboard operation has been confirmed by user testing. Update both Macs to receive the complete clipboard fixes.
• Updated the feature-focused README in all four languages and the engineering documentation.

Downloads

• macOS Apple Silicon: signed and notarized DMG.
• Windows x64: installer.
• Windows on ARM: ARM64 installer.

Close the running app before installing over the previous version. SHA256SUMS contains checksums for all three installers.

Frame interpolation remains experimental and is currently available only on supported Macs. Smoothness and artifacts depend on the source frame rate and device performance. This release was compiled for all three platforms; Mac-to-Mac clipboard behavior was additionally confirmed by the user.

YourDesk 1.26.0909 build 1855

About page and update reminder

• Remove the Core ML super-resolution, RIFE and FSR license expanders from About. A short attribution is available in the GitHub README, and full license texts remain bundled with the application.
• Remind users to quit the running app before installing and replacing the previous version.
• Replaces the withdrawn build 1848 release.

Streaming controls

• Configure remote source FPS from 5–60 (default 20), target bitrate from 1–64 Mbps (default 12 Mbps), and GOP from 1–300 frames (default 10).
• Explicit FPS settings take priority over enhancement strategy multipliers. Bitrate is an encoder target, not an instantaneous network traffic cap.
• H.264/HEVC can now use inter-frame encoding with negotiated GOP settings. Older peers retain compatible behavior; update both ends for configurable GOP.
• Add Viewer pipeline diagnostics for received, decoded and rendered frames, sequence gaps and decoder recovery.

Experimental frame interpolation

• Add RIFE 4.25 Lite through Core ML on Apple Silicon with macOS 13 or later. Windows interpolation is not yet supported.
• Continue interpolation during dragging and other input, and improve scheduling when combined with FSR or Core ML super resolution.
• Show actual Render FPS in green while interpolation is enabled, including generated frames. Stabilize enhancement status during short transitions.
• Screen enhancement and interpolation both default to off. Existing saved preferences are preserved.
• Interpolation runs in Viewer and does not by itself require updating the remote Client. It may add latency or distort fast motion; missed deadlines fall back to real frames. A 2× display rate is a goal, not a guarantee.

Desktop usability

• Close Viewer with one action and return to the main window.
• Support Cmd+W / Cmd+Q on macOS and Ctrl+W / Alt+F4 on Windows for local window/app actions; preserve clipboard shortcuts.
• Show hover bubbles immediately. Move FPS, bitrate and GOP explanations into tooltips and simplify enhancement settings.
• Rename the development launcher to runUITest.command and provide a generated clientUI.app launcher without a Terminal window.

Packages

• macOS ARM64: Developer ID signed and Apple-notarized DMG.
• Windows x64 and Windows ARM64 (WOA): NSIS installers; Windows executables are not Authenticode-signed.
• Bundled Core ML super-resolution models remain QuickSRNet Small 2× and SESR M5 2×. RIFE model source, conversion inputs and license are included in the repository.

Validation: cross-platform release builds and syntax checks. No additional automated functional tests were run for this release.

Screen enhancement

• Added an experimental Screen Enhancement settings page with FSR 1 (EASU + RCAS) and Core ML backends.
• Bundled QuickSRNet Small 2× and SESR M5 2× for Apple Silicon Macs. Selecting Core ML reveals a model selector, defaulting to QuickSRNet Small. Model availability is checked at startup; failures fall back to FSR 1.
• Reduced transmission width and height to 75% of the original when enhancement is supported by both endpoints.
• Added three strategies: Auto adjustment, Display smoothness priority, and Network load priority. Auto preserves the existing FPS and rate policy; smoothness requests twice the source FPS limit with the configured bitrate budget; network priority retains the FPS limit and halves that budget.
• Added a toolbar indicator with the active strategy, actual backend, source/transmission/display dimensions, bitrate and fallback status.
• Empty unsupported-method groups now display “None”.
• No frame interpolation is included. Actual FPS and bandwidth depend on the hardware, encoder and network.

When enhancement helps

Current user experience indicates that enhancement benefits become more noticeable at higher remote desktop resolutions, such as 1440p or 4K. Scaling each dimension to 75% leaves 56.25% of the original pixels, a 43.75% reduction. The percentage is constant, but the absolute number of pixels saved increases with resolution: 907,200 per frame at 1080p versus 3,628,800 at 4K.

Actual FPS and bandwidth depend on the selected strategy, encoder, hardware and network bottlenecks; Viewer upscaling also costs more at larger input sizes. Lower-resolution desktops and dense small text may show more noticeable detail loss.

Streaming and usability

• Added versioned, composable streaming parameters with capability negotiation, session/revision tracking and effective-setting acknowledgements.
• Retained compatibility with older streaming parameters. Update both endpoints for the new 75% resolution and strategy controls; changing a Core ML model only requires the Viewer update.
• Closing the Viewer now brings the main window back to the foreground.

Downloads

• macOS Apple Silicon: Developer ID-signed and Apple-notarized DMG.
• Windows x64: NSIS installer.
• Windows on ARM (WOA): installer containing native ARM64 application binaries.
• SHA256SUMS: checksums for the three installers.

Windows installers are not Authenticode-signed. Core ML is available only on supported Apple Silicon Macs; Windows uses FSR 1. Windows ARM64 builds have been compiled, but WOA hardware behavior has not been validated on a physical device.

Validation

Go builds and JavaScript syntax checks completed. Both Core ML model packages compiled successfully. Release packaging validates macOS signatures, notarization tickets and Gatekeeper acceptance. No additional functional regression suite was run.
