i did a fragment shader test on iphone 3gs (power vr sgx530) and i estimate i get something around 500 Mflops ? is my estimation in the correct order of magnitude or is my code much too slow (code compiled with iphone sdk 3.1 and run under ios 3.1.2) ?  
  
  
  
  
  
has someone got detailed informations on power vr sgx530 performances in a fragment shader ?
