Intel has published a Linux patch which brings a new adaptive sharpening feature to the company's upcoming Lunar Lake Xe2 integrated graphics (via Phoronix). According to the patch notes, this adaptive sharpening filter will be available on Lunar Lake and future devices, and can be used for multiple use cases, including gaming and images in general.
As with most patches for new features on upcoming hardware, it's not completely certain what exactly the new adaptive sharpening feature does, but the gist seems to be that it can selectively sharpen portions of an image. The cover note for the patch states "it works on a region of pixels," and that the filter "blend[s] the sharpened image to original image." There are more technical details in the rest of the patch notes, but nothing that can realistically tell us how good this solution would be.
