    It is much more complicated than that : CPU cycles vary depending on context : cache locality, pipelining and superscalar micro-instructions are the most prevalent factors that make cycles varying...

    Debian is the base of many distros, it must be as pure as possible. Being totally free removes constrains for other distros that want to stay fully free (gNewSense and the like) and do not stop...

    The game publisher uses OpenAL, not PA : disabling PA if needed would be the role of the distro, or OpenAL, or even PA, not the game. That's pretty much my point in most of my posts : game studios...

    1. "pasuspend" is not out of the box. PA disabling should be done automatically.

    2. When working with PA, these libraries eat 30% of my core 2 duo, which is too high. It also eats the system bus...

    IsawSparks is true : today's games are modeled after XBox360 capabilities : hardware assisted video and software mixed sound, and that perfectly makes sense : mixing audio is essentially free on...

    PA, ALSA and OSS are not facilities available for game developers, but for software mixing libraries like OpenAL and FMod. Topic changed since long ago ... Nobody care about ALSA or PA in the video...

    These projects mostly use OpenAL and Neverball is based on Quake engine, which is commercial grade. Here only the high-level library counts. Still, what you say is true, but I would try to rephrase...

    Of the few games I play under Linux, Neverball (OpenAL), vDrift and PrBoom had severe drops. And SDLMAME is just unusable (plain SDL sound). All of this is on an unmodified Ubuntu 9.04 and 9.10. All...

    This was the case in the DOS days, as for the myth of sync on sound output. Game developers expect a much higher level interface, which is usually an embedded software mixer that needs a plain...

    Except that the norm is now DirectX 10 and companies are looking toward DirectX 11. To be more precise, all AAA titles are tailored for XBox360 hardware, which is between DX10 and DX11. You need at...

    To avoid flaming against the Registry idea, I would say that the equivalent of "User Shell Folders" in simple text files would be cool : a /etc/directories with a simple syntax and a per-user...

    Of course ! And it works so well. But it is not a viable solution for games, which cannot be rebuilt for every distro out there (too many of them, too difficult to test). Windows sucks in that...

    Being in the video game industry for years as a developer, I just see a problem in your PA/OSS/ALSA/OpenAL/... flame war (no offense meant, it is rather constructive).
