   GLSL Compilers
  Well, I may be living in the past (and dwelling on an issue of ~10% performance (thats the only figure i've seen, from shader x3) but glsl compilers have been sub-par, nvidia's was non-standards compliant due to its cg backend, and ati's was sub par for another reason i can't quite remember. So anyways, my question is simply this: have the compilers been improving? Do we know if our ihvs have been improving the compilers in their drivers?  Theres no question where the future of openGL shading languages is, but i'd still like to know how things have been evolvingthanks-Dan   
  Well it is way better than it was a year ago, i havnt had any problems compiling any code samples from the net. Im running a Radeon 9600Pro.
