      It is probably best to wait until something is committed - sometimes there can be many proposals thrown at the wall and then rejected after further investigation, or like the triple buffering one, become a long saga that takes months to years to polish and fix any regressions and bugs.

      Also, while this was tested on nvidia, but unless I am mistaken, there is nothing suggesting this will only impact nvidia - everyone with high refresh displays could benefit.

        The reporting is subpar once again. Why would this restriction be limited to Nvidia GPUs only? The "4.1 ms" interval applies to any graphics card that is trying to render at 240 Hz. Also it sounds like the limitation in Mutter is a generic one and not something specific to Nvidia cards.

        Reading through the merge request, it seems that Nvidia is suffering the most because they are using EGL streams. The MR seems to imply that with EGL streams there's an inherent additional 0.5 ms delay which is not present with GPU vendors who provide proper drivers.
