So I got a new laptop few weeks ago. All games were running perfect and Sony Vegas was rendering videos with 2.90Ghz usage. But since yesterday games use much lower fps and Sony Vegas rendering at 1.15Ghz (Screenshot while rendering video: http://gyazo.com/17197c3554bf9b062b294ea8f50f9e80 )
I didn't switch anything in BIOS or power options.
So I got a new laptop. Till yesterday it was working fine with fps on games doing well and CPU at 2.90Ghz when playing games or rendering videos with Sony Vegas 12. Since today it uses 50% (1.15Ghz), slow on rendering and low at fps. (screenshot while rendering video http://gyazo.com/17197c3554bf9b062b294ea8f50f9e80 )
Also my power plan is switching automatically to 'power saver' after the start of laptop.
