Hello,
You may want some screenshots which expose the performances with rembrandt
at WAAJ and the PAF team DR-400 and the computer with Nvidia GPU 560 TI i
refer to .
It could help you to understand why you are getting that poor performances
with your pretty fast beast GTX 670M.
Let's consider right now the 560 TI is an old outdated GPU.
