Thread: Firefox 93 and newer editions will work slower with old hardware - no more OpenGL compositing

    Angry Firefox 93 and newer editions will work slower with old hardware - no more OpenGL compositing

    With Firefox 93 Mozilla is throwing away OpenGL compositing (rendering), only Webrender will stay.
    User will need compatible GPU, otherwise FF will use software Webrender.
    I cannot find exact data about Webrender system requirements. It worked on AMD Terascale 2 with OpenGL 3.3 support. Maybe it'll work with all AMD/ATI Terascale chips (Radeon HD 2000 series and newer), but not previous ones.

    Another flaw: even with fully compatible GPU with slow CPU Webrender works slower than OpenGL compositing (~ 20% slower).
    Here for slow CPU I mean this: using FF loads CPU to 100% continuously.

    You may use FF ESR (78, 91) for some time: https://wiki.mozilla.org/Release_Management/Calendar

    Mozilla is eliminating desktop users.

    Quoting from this bug:
    Code:
    We have never shipped the OpenGL compositor on Linux
    so I am really curious what this thread is about.

    It worked for me.

    Mozilla wrote wrong answer: 1731688 - OpenGL compositing works faster than Webrender, but is throwing away

    At least I get system requirements for Webrender: https://bugzilla.mozilla.org/show_bug.cgi?id=1731664

    WebRender will work without hardware acceleration on all platforms.

    WebRender requires D3D10.0 level hardware on desktop on OpenGL ES3 on mobile.

    AMD Terascale and actual GCN-architecture (Windows, Linux)
    Nvidia (Android), Tesla G80+: Linux, Windows 7+
    Intel HD Graphics Sandy Bridge and higher (Linux)
