I didn't see anything in the MagicEyes docs about performance counters such as cache hits/misses, branch mispredicts and pipeline flushes.

Do you know if the 920/940 are capable of reporting performance statistics like that? It would be *very* useful for optimizing a 3D library. :ph34r:
 
The core doesn't report that kind of stuff, but you can get a lot of info from debuggers - some will tell you the normal of cycles required to run a subroutine for example, so you task would simply be to get it to run in the minimal amount of cycles possible.
