I swear god I tested this, with exactly the same condition. Ok, just to be sure let's test this again... And.. I can't reproduce the situation I described above... Now same flags gives same hash rate and GPU usage. So I guess I was wrong.

<p>Why guiminer is using different amount of GPU each time I restart my computer?
I'm running <code>guiminer-20121203</code>, <code>NVIDIA GeForce GTX 670M</code>, <code>poclbm.exe</code> with flags  <code>-s 0.005 -f 60</code>
What I noticed was, it was <strong>35Mgash/s with 75% GPU usage</strong>. And after I restart my computer, it became  <strong>50Mgash/s with 100% GPU</strong> usage with the same flag settings.</p>

<p>Also, before when I tried only with flag <code>-s 0.010</code> it utilized <strong>100%</strong> GPU, but without restarting computer, using flag <code>-s 0.011</code> reduced GPU usage to <strong>60%</strong>.</p>

<p>What's going on?? </p>

Why guiminer is using different amount of GPU each time I restart my computer?
I'm running `guiminer-20121203`, `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??
