gaming on linux

[kaladhar]

i'm very new to Linux. i'm running linux mint 13 Maya 64 bit edition in my rv518 laptop. it has nvidia geforce gt520m with cuda gpu. i installed playonlinux to play nfs most wanted. I'm running the game but the graphics are very bad. i'm getting the game in gray colour. i think installing the graphic card drivers could improve the game performence . i installed nvidia graphic drivers. i don't know how to use it. i installed bumblebee and tried to run the game and i'm getting the below error
-------------------------------------------------
[ 1005.603800] [ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect.
[ 1005.603913] [ERROR]Could not connect to bumblebee daemon - is it running?
-------------------------------------------------
can u help me sorting this out?

Experiment using one of the other Nvidia drivers, and/or using Wine.
