It uses glamor for acceleration, just like modesetting, but it is much better in terms of screen tearing. On intel, modesetting is the *only* way to use glamor, since the 'intel' driver uses old UXA or SNA stuff (sort-of native 2d acceleration that Intel doesn't really want to maintain anymore) > also, with your current config does "glxinfo" show support for the > missing extensions? interestingly enough I do not see support for > GL_EXT_shared_texture_palette nor GL_NV_register_combiners on my > intel system. it' been a while since i've done any 3d work so I'm > not %100 sure of the criticality of those last two extensions are. I think doom3 would specifically error if an extension was a hard requirement, not segfault :)
