In my last WoW test all render correct but there is somewhere an sw fallback an an bug in the driver ( if you enter OG the game crash ) and i dont have installed this libary
Use driconf to tell Mesa to advertise the S3TC extensions without it. WoW won't crash so long as the extensions are there, but you'll get a black screen until S3TC textures are at least partially supported.
I think it would be a good thing for would-be devs to see where to optimize.
I haven't seen an actual list, although I suspect most of the devs would point to the same general area of the stack if asked (state management/command submission, synchronization/flushing, memory management).
Mostly the nasty areas that are hard to make reliable and easy to break.
Most of the drivers use two compiler stages - one common, and one hardware-specific...
Thanks bridgman and marek for clarifying.
I'm amused at the extra translations back and forth between Mesa/TGSI but I suppose this is allows maximum code re-use/sharing between classic and gallium3d until the new stack is more fully in place and can be re-factored/cleaned up.
