No, and moving windows or opening applications is a poor way of testing 

To get full benefit of forte you should enable all the architecture specific 
optimizations (-xtarget=native), enable inline expansion of math (-xmlib) and 
loop prefetching. 
The places you will get the biggest speedups are still in algorithmic dependen 
calculations such as rendering in KHTML, searching in KMail or highlighting 
in Kate.
The speed improvements are only in 10-30% range (higher for floating-pointer 
maybe, but not much of that is used in KDE), so don't expect much you can 
notice without benchmarking.
