Confirmed on Pineview and Diamondville now so just about anyone with a netbook can join in the fun.
https://en.wikipedia.org/wiki/List_of_Intel_Atom_microprocessors#Single- core_Netbook_processors In both cases, Mir demos run 60Hz-smoothly (Diamondville requires a workaround in bug 1388490 first). Only Unity8 and mir_demo_client_eglplasma are unbearably slow (first observed in bug 1275684). ** Summary changed: - Unity8 on Intel Pineview performs poorly + Unity8 on Intel Atoms performs poorly -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1580792 Title: Unity8 on Intel Atoms performs poorly Status in unity8 package in Ubuntu: Confirmed Bug description: (problem forked from bug 1549455) Unity8 on Intel Pineview performs very poorly. Frame times appears to be up to 900ms, Qt's renderer thread using 100% CPU. Running unity8 with MESA_DEBUG=1 EGL_LOG_LEVEL=debug reveals a few MESA errors: http://paste.ubuntu.com/16344427/ Quoting @vanvugt "Those Mesa errors "Mesa: User error:" all look like OpenGL features that Unity8 is hitting but mir-demos don't. So those gl calls are also good candidates for explaining poor performance, especially if Mesa is falling back to software rendering for them." Since Qt tends to perform just fine on that hardware in X11, something isn't right.
