LAG PROBLEM NBA 2K13

Greetings everyone.. i'm playing nba 2k13 in my laptop with specs as follows:
ASUS K43SD model
Intel core i3 2350m, 2.3ghz
Nvidia Geforce 610m 2gb
2gb ddr3 ram
win7 home basic operating system 64-bit

i'm really greatful if someone can help me decrease the lag in my game.. thank you so much..

Lower settings. Especially player quality probably.

another thing that might help is use your graphics card program to higher the settings instead of 2k13. Increase AA and such in cataylist control or nvidia control

i have lowered all settings.. and i've already set it in window mode with lowered screen resolution.. still its too laggy.. do i need drivers for this game?

thanks for the help guys.. its working just fine now.,,
