Enderboi No tlp won't switch gpus just save you a little juice. There are some people that got bbswitch working which is a utility that allows you to turn off your nvidia card when not using it, but I've seen no good or definitive guide.
For me bbswitch never worked. I have GTX 960 M
Edit: You can play games just fine I guess, also you should have installed 32bit driver from hardware manager if you plan on playing windows games.
