Hi, I've already followed all the steps stated in other threads, after doing a serch. The issue: As soon as I unplug the AC the performance drops dramatically (during SFIV benchmark goes from 100+fps to 25fps). Tried: - Changed energy settings in AlienFusion (High performance > Advanced > Graphics processor : Max performance on both AC and Batt). - Changed energy settings in Windows Control Panel (High performance plan > Advanced > GPU Power state : Max Performance). - Changed Global Settings in Nvidia Control Panel: Power management mode > Prefer maximum performance. - Updated BIOS to unlocked A08 and disabled Intel Speedstep, but I can't find any other values that I should change. Is there any other thing that I could try? (PS: Sorry about any spelling mistakes, English is not my first language)
