    That is the impression I got when playing those games, that they were going through the ALSA device.

    of course! that's what quite a lot of programs/games are doing. actually it is a quite easy task.

    Would it be possible to just bypass pulseaudio and talk directly to ALSA when playing games?

    As far as I understand there are virtually no latency-centric test profiles for PTS at the moment.
    I tried to write profiles for latency-focused benchmarks like D-bus-pingpong or latt, but I the bits of documentation I've managed to google and dig up on phoronix-test-suite.com were insufficient. Is there a reference or tutorial or something on writing test profiles?

    This is similar to their desire to have better Linux OpenGL drivers but not with any real commitment for major changes upstream but are looking to more or less offload the work to the community.
    Again, people like to pick on Lennart Poettering but at least he actively tries to DO SOMETHING to fix up the Linux desktop, rather than just yakking over and over.

    Phoronix: Ubuntu Desires Lower Audio Latency For Gaming

    At the Ubuntu Developer Summit in Copenhagen today, developers discussed audio latency for gaming on the premise that "audio latency is relatively high on Linux and we need to be competitive with other platforms."..
