    Phoronix: Ubuntu 20.10 / GNOME 3.38 Could See Better Intel Gen9 Graphics Performance

    While more laptops are shipping these days finally with Icelake "Gen 11" graphics and Tiger Lake with "Gen 12" graphics are expected soon, there still is an incredible amount of hardware out there making use of Intel Gen 9 graphics that have been in use since Skylake. It's looking like for the Ubuntu 20.10 cycle, there is going to be an emphasis on offering better performance for this very common generation of Intel UHD Graphics...

    Mutter 3.38 will get a lot of big changes soon so there will be a flood of bugs and regressions. It’s good to have a guy like Daniel on the team.

      UHD 620/630 graphics are simply a bit too slow for a smooth 4K experience, despite the name. Remember, Gen9 graphics go back to 2015 (Skylake) and are more or less unchanged since then, except for some clock speed improvements. Windows has a well-optimized compositor, but the 4K experience is rather sluggish with UHD 620/630 on this OS, too.

      Apple only uses high DPI displays. Do you think it is a surprise that Apple only uses Iris graphics? Nope. Iris iGPUs have roughly twice the number of shader units and they benefit from fast last level cache memory. You simply need that kind of power for smooth 4K desktop rendering.

      So, if GNOME gets some further performance improvements for systems with slow GPUs that's great, but it's unlikely these slow iGPUs will ever work well for 4K.

        I have a 630 ...more precisely P630 (but I havent found any differences). And on 4K Gnome running PopOs20.04, I have no issues at all. Everything is rather smoothly. Ok gameing sure not possible. but everything else is ok.

        edit: Youtube [email protected] feels more like [email protected] but not really lame. "normal" 4k clips (with 29fps?) are fine.

          Smooth means 60 fps with little or no drops, in all typical situations. That simply won't happen with these GPUs.

          Yeah, that alone makes it a no-go.

            The strange thing would be if on windows there is no such problem doing 4K on 630

              exactly it is not the chip IMHO.

                Spent a day with a 4K monitor and good/bad news: gnome-shell performance at 4K with Intel HD Graphics 630 is quite bad. So that will be another goal this cycle...
                Eh.. then stop using the Xorg session?

                The Wayland session works so much better, that's why it's default.

                  Ok 60fps in typical situations. 4k any desktopstuff works. 4k60fps is not so common. [email protected] yes but there are no issues.
                  I would say that this is typical. Gaming [email protected] fps is also very untypical because it might not be even possible with a nvidia 2080 rtx.
                  So everything is smooth but not in the Luxury case of [email protected] I bet in VLC it is better.

                  Im rather sensitive to such stuff. Yes the quadro T1000 is snappier on X11 but intel is smoother on wayland.

                  But with my latest PopOS Nvidia setup and autotiling there is no wayland switchable anymore by default

                    Thanks

                    p.s.: it is a bit of an unfortune that the autotiling of PopOS is not so much working on Xorg
