[SUPERSEDED by v6.1.0-vrr6] v6.1.0-vrr5 - Smooth VRR for SteamOS/Linux + Windows 10/11 (beta)

Warning

This release is superseded by v6.1.0-vrr6 - lower latency, better calibration, and VRR is now a simple opt-in checkbox. Please use that release instead.

v6.1.0-vrr5: Smooth VRR game streaming for Linux and Windows This is a special version of Moonlight that fixes VRR game streaming on Linux and Windows. VRR includes FreeSync, G-Sync, and Adaptive-Sync. Previously, VRR did not always work as intended because Moonlight’s frame pacing was not properly synchronized with the display. This could cause uneven motion, stutter, or tearing, especially when the stream FPS did not exactly match the display’s refresh rate. This build fixes that by synchronizing frame pacing with the display, so frames are shown at a smooth and steady pace. The result is smoother game streaming on VRR displays. ## Supported platforms | Platform | Download | | ------------------- | ---------------------------------------------- | | SteamOS / Linux | Moonlight-VRR-6.1.0-vrr5-x86_64.flatpak | | Windows 10 | MoonlightSetup-x64 / MoonlightPortable-x64 | | Windows 11 | MoonlightSetup-x64 / MoonlightPortable-x64 | ## How to use VRR pacing To use the new VRR pacing: 1. Enable V-Sync in Moonlight settings. 2. Set Moonlight to Borderless Windowed mode. 3. Set the stream FPS to the same as, or lower than, your display’s refresh rate. 4. Use a VRR-capable display with VRR enabled. ## New in this release: Linux support VRR pacing now works on Linux and SteamOS using the Vulkan renderer. Install the Flatpak with: bash flatpak install --user ./Moonlight-VRR-6.1.0-vrr5-x86_64.flatpak ```` This build installs next to the normal Flathub Moonlight app and uses the same settings and paired hosts. ## Windows support Standard VRR pacing works on both Windows 10 and Windows 11. ## Optional Windows 11 feature: Smoothest VRR Windows 11 users can enable an optional setting called: **Smoothest VRR (OS-scheduled presentation)** This lets Windows handle the final timing of when each frame appears. It can make VRR even smoother and fully tear-free. To enable it: **Settings** → check **Smoothest VRR (OS-scheduled presentation)** This option only appears on Windows 11. ### Trade-off This mode adds about one extra frame of display latency. Use it if you want the smoothest possible VRR. Leave it off if you prefer lower latency. If your system does not support this mode, Moonlight will automatically use the normal VRR pacing instead. ## Beta notice This is a beta build. Feedback is welcome. For troubleshooting, please include your session logs. On Windows, logs are next to the portable `.exe`. On Linux, run Moonlight from a terminal with: bash flatpak run com.moonlight_stream.Moonlight Linux logs can also be found here: bash ~/.var/app/com.moonlight_stream.Moonlight/cache/ ```
