These Ryzen chips look like game changers for laptops. Intel has stagnated for so long in comparison. Preliminary reports show near desktop performance for the Ryzen chips, and they blow Intel mobile chips out of the water - like 200% faster and much better thermals for sustained computing. On the downside, I've read rumors that Intel is leveraging its OEM relationships to keep AMD processors out of top of the line models such as Thinkpad X1. Intel is also preventing AMD laptops from using TB3. So it seems the options for an AMD laptop right now will remain limited - but I hope this will improve over the next year or so as demand increases for the cheaper and faster AMD laptops. You should not be buying an Intel laptop anymore IMO.

Meanwhile I would be happy if my AMD GPU was able to support OpenGL 4.1 like it used to do with fxglr, instead I have to be happy that it does OpenGL 3.1 at all with Mesa 20, or reboot into Windows to enjoy DirectX 11.

  Which GPU do you have? According to https://mesamatrix.net https://mesamatrix.net the radeonsi driver for GCN and RDNA cards supports OpenGL 4.6 (the latest), and the r600 driver for older TeraScale cards supports 4.5.

    Which given my hint about FXGLR doesn't do me much good. https://www.techpowerup.com/gpu-specs/radeon-hd-6310-igp.c2286 https://www.techpowerup.com/gpu-specs/radeon-hd-6310-igp.c22... With fxglr, I enjoyed OpenGL 4.1, hardware video decoding, even though as you see from the specs, it can do more than that on Windows. With the wonderful open source driver, I get OpenGL 3.1 without hardware video acceleration.

      Do you mean fglrx? Regardless, the problem is nobody wants to spend development time supporting 10+ year old cards when there isn't enough time to support all the features on newer cards.

        Indeed, which proves the point that having FOSS drivers is just publicity if there isn't anyone willing to do the job. My laptop works perfectly fine, so the consequence is me switching to Windows, where Asus still keeps its DirectX 11 drivers for the laptop up to date for Windows 10, although the laptop was bought during Windows 7 days.

        Or that whoever manufactured the device didn't care about supplying/maintaining drivers for Linux so the community is left maintaining them. There's nothing stopping the device manufacturer from spending the time to support the device like they do on Windows, they just don't think it's worth it due to the smaller market share (which makes sense from a business perspective).
