I know what's going on, but I'm not sure how to fix it. (you'll probably know some of this alread) Your laptop has both integrated and discrete graphics and switches between them as required because the integrated chip uses less battery power. I think I know how to fix it based on a video I watched demoing how this stuff works, I recall there being an option within the context menu of.exe files that allows you to force one adapter or the other.

On my new laptop I have NVIDIA GeForce GT 540M installed and driver up-to-date, but when I configure Sonic Generations, it only allows me to choose Intel® HD Graphics Family.

Might also be worth mentioning that I can play games like Half-Life 2 and Left 4 Dead 2 very smoothly, but I dunno if those games can compare to Sonic Generations graphic-wise, I am so bad at this! =D
Found another post which might describe my situation better:
I read up about connecting to a monitor through HDMI will magically make the graphic card compatible, but it still does not show up for me. T.T
C:\Program Files (x86)\Steam\steamapps\common\sonic generations
and then right click on ConfigurationTool.exe and then I think there should be an option to get it to run using the discrete (the 540) chip. I think there might also be an option to make it the default. You might have to do the same to the game's main .exe.
EDIT: OH WAIT!! You need to add that option to the context menu. This done through the Nvidia control panel. Open the nvidia control panel (right click on the desktop and select it), then go to view and check "add run with graphics processor to context menu".
