"… The LLVM JIT optimizations combined with the new multi-threaded
OpenGL stack have yielded a doubling of the frame-rate in "a very
popular MMORPG" (which is code for "WoW"). Yikes!
The multi-threaded OpenGL feature may appear in a future version of
Tiger, but it currently works exclusively in 10.4.7 on the new Mac
Pros. …"

Yes please !

As nice as this sounds in theory, lets wait untill people can get
their hands dirty with it. Most things like this have a huge caveat
which no one mentions from the get go.

Who knows, maybe it will be 2x faster, but somehow I doubt that.

The LLVM optimization is most likely what leads to such improved
performance. Jitter shouldn’t see any improvements from MT OpenGL,
since all OpenGL commands in Jitter are made from one thread. LLVM is
Leopard only.
