Can't play Watch_Dogs and some other games using switchable graphics on a Sager laptop

Hey guys, even after setting the Watch Dogs.exe to run on my dedicated Geforce 675m in the Nvidia Control Panel, the game continues to run on my Integrated Intel Video card. A similar problem also occurs when I try to run the Dolphin GC/Wii emulator with my Nvidia card. Do you guys have any ideas on how to fix this screwy Optimus technology? I have updated my drivers to 337.88 and restarted my computer.

 

hi
strange one as the 337.88 is a game ready driver for watchdogs.
changing the exe in nvidia control panel should sort it as this also happened with titanfall.

when you changed in nvidia control panel did you scroll down and hit apply as quite a few people had missed this in the past.

are you running on high performance and also plugged into mains.
only other thing i can think of is a conflict with previous driver (which was loaded before).

you could dry a manual clean in safe mode to make sure all the registry crap has been deleted (link in sig below).

 

What happens if you do this?
