Why guiminer is using different amount of GPU each time I restart my computer?
NVIDIA GeForce GTX 670M,
poclbm.exe with flags
-s 0.005 -f 60
What I noticed was, it was 35Mgash/s with 75% GPU usage. And after I restart my computer, it became 50Mgash/s with 100% GPU usage with the same flag settings.
Also, before when I tried only with flag
-s 0.010 it utilized 100% GPU, but without restarting computer, using flag
-s 0.011 reduced GPU usage to 60%.
What's going on??
