sorry, I should have warned I was reviving an old thread... nevertheless, the problem is current. and those directives don't solve it. the whole DoomConfig.cfg copied over from base (which works - base Doom3 works flawlessly on Intel GMA!) doesn't do anything. and I'm using alsa.
no, this argument won't hold, unfortunately (or not). Doom3 game by itself works like a charm on Intel GMA965 (low-res and low-quality settings) and it unpacks all the same GUIs, textures, assets, etc. from base/pak000.pk4 et al. try it yourself; if you don't have license key files, you can use this. edit: it must be related to this thread.
