What is taking the most cpu time? I love optimizing code, and I might take a stab at it, though I assume all the low hanging fruit has been picked a long time ago...
As far as I can tell, Dolphin is complex enough that finding a bottleneck which can be optimized is more time consuming than actually optimizing it. So.. if you love optimizing code, you'll have to spend some time finding optimize-able code first
Anyway, hanging around in our IRC chan is probably more effective (the general rules apply, i.e. be patient for answers
).
Isn't that what Vtune is for?
