From what I can tell, that slider has always been on high-performance for me.
StV == Sync to VBlank
Video Texture Adapter: StV off
Video Blitter Adapter Settings: StV off
Cursor Shadow: off :)
Performance: StV off, Allow Flipping on, Image Settings: High Performance
Antialiasing/Anisotropic: Application Default
Texture Sharpening: on (?)
Overclocking disabled.
Could it be that you'd installed some kernel or driver update before the reboot? 195.22 driver here.
