Note that Moonlight sees the "Driver Version" column, not the "Release Version" column.I own a Huawei Matebook D15 with Manjaro Gnome. See Intel's page on driver version semantics for more details on both the new and the old version semantics. We would be catching the driver baseline as part of the build number which would result in incorrect matches as mentioned above. Using this "proper" version checking logic on drivers below version 100 would be incorrect. despite having a "higher version" in the traditional sense. On the graphics drivers download page, we can see that 15. Prior to version 100, the 3rd version field was a mapping of the "driver baseline" and doesn't indicate the chronology of the releases. Certain parts of the version have specific meanings that are unrelated to the chronological order of the driver releases (which is what Moonlight needs to check).įor example, the left-most portion of the version number is the WDDM version.
Next time, better pattern detection please with regex.Ī "proper regex" would not have caught this. This should be very easy and quickly to fix. I would assume there is some stupid dirty code in Moonlight just looking at the last 4 digits of the driver, and the new 30.0.101.1069 is detected as an "old" driver, because of the 1069, which would be in the previous build a very old version, when it would have been xx.0.100.1069 I guess because Intel changed the driver numbersįrom 30.0.100 to 30.0.101. So I guess this is just a bug in Moonlight code, with bad pattern detection. Update your Intel GPU driver to enable HEVC! Did Intel mess something up pr remove something in that driver?Įdit: Looked into Moonlight logs and this line is the culprit I guess:Ġ0:00:00 - SDL Info (0): Detected buggy Intel GPU driver installed. Whats going on? Is this a bug of the Intel driver, so hevc decode is broken everywhere? I cant think it is just Moonlight related. Since I upgraded to 30.0.101.1069, Moonlight says the hardware doesnt support HEVC decoding anymore. Same for me on UHD630 on 8th gen Intel 8750H, it is not Iris Xe only.
