Right, we may have to look at that. We're currently looking into a non-GuC workaround as there doesn't seem to be any OpenCL kernels for the Surface Pro 7/Surface Laptop 3 devices (that's another issue...), but we will keep that in mind for the older devices. > No idea about the details of what goes on on Windows.

Just wanted to know if there's any special stuff on Windows. Given that the newer devices (Pro 7/Laptop 3) don't seem to have any IPTS firmware at all (OpenCL kernels etc.) could suggest that they might use a different implementation (maybe non-GuC/no GPU processing), altough the IPTS driver still seems to be in use. Thank you for sharing your insights, this has really helped us.
