Hey guys, I'm new here, but I see this is the place for any info in regards to tinkering with such things. Anyway, I was playing BF3 yesterday, and noticed my FPS went down horribly making the game unplayable. I've started eVGA Precision X just to see that my max GPU usage was roughly 71%, and my GPU core clock was at 950 Mhz and temps around 83 C. This freaked me out, since I did not implement any overclocking via the Precision software. On a side not, a day earlier I was messing around to see if there's a way I can control or even see the fan speed, and I've installed the Lenovo Energy Management software from a Z580 (I think that's what it was). Also, for some reason, the GeForce drivers were disappearing on me. I never turn off my laptop, and trying to pay BF3 yesterday, I saw horrible performance when I got into the game, so I closed it, shortly thereafter realizing that Device Manager was showing "Unknown VGA Device" instead of GTX 660M and NV CP wasn't in the context menu. After reboot, they were installed again. So I uninstalled the Energy Management app from the Z580, and re-installed the proper one, and re-installed the GPU drivers, I have yet to see if the issue persists. Does anyone know if the Lenovo Energy Management software is the culprit for this? Or is it a bigger issue?
