    **★★★★★ Excellent Video Upscaling Extension!**

    Sharpview is a fantastic extension for improving video quality on YouTube and other streaming sites. I'm using it with an AMD RX 6800 XT and a 1440p monitor, and it does a great job upscaling 1080p video. The GPU acceleration works smoothly, and I really appreciate the ability to adjust sharpness, reduce noise, and compare the enhanced video with the original in real time.

    The extension is lightweight, easy to configure, and offers a noticeable improvement without unnecessary complexity. It's especially nice to have a free, open-source solution like this for Firefox.

    **One feature I'd love to see added is support for newer versions of AMD FSR**, ideally with the ability to select different FSR versions in the settings. I understand newer FSR technologies may have technical limitations when applied to browser video, but having more upscaling options would make an already excellent extension even better.

    Great work by the developer! I'm looking forward to future updates. Highly recommended!

    Thank you so much for the kind words and the detailed feedback! I'm glad it works well on your RX 6800 XT at 1440p.

    About newer FSR versions: I looked into it carefully, but unfortunately they can't be applied to browser video. FSR 2, 3 and 4 are temporal upscalers: they rebuild detail by combining several frames using motion vectors and depth information that a game engine provides for every frame. A video only contains the final image, so that data simply isn't there. FSR 4 also relies on dedicated hardware on RDNA 4 GPUs, which isn't accessible from a browser. FSR 1 is the only version that works on a single image, which is why Sharpview uses it.

    That said, I'm working on adding more upscalers. Version 1.4.0 adds an Anime4K quality for anime and cartoons: it cleans up compression artifacts and redraws the lines at a higher resolution (it needs a capable GPU, and your 6800 XT will handle it easily). You can select it from the popup or with Alt+Shift+G. More options may follow in future updates.

    Thanks again for the support!

    Top! Fantastic, useful for amd gpus without the nvidia video upscale, especially on Linux without the video upscale options. It would be amazing if it was possible to implement heavier version of FSR for powerful GPUs

    Thank you! I'm really glad it's useful on Linux, where browsers don't offer any video upscaling of their own.

    About a heavier FSR: FSR 1 has no heavier mode, as it always runs the same two passes. The newer versions (FSR 2, 3 and 4) are temporal: they need motion vectors and depth data that games provide but videos don't, so they can't be used in a browser.

    I'm studying other upscalers that can make use of a powerful GPU, though. The first one is in version 1.4.0: an Anime4K quality for anime and cartoons, which cleans up compression and redraws the lines at a higher resolution. You can choose it from the popup or with Alt+Shift+G. I'm also looking at heavier options for regular video.

    Thanks for the feedback!
