Even though laptops have been known to play games ok I personally would'nt recommend it,unless it has specs to equal or rival some of the top end machines today.

But..first I would check in your task manager,and go to running processes,and uncheck everything that you really don't need,as anything like real time virus scanners can interrupt things like games.

I would also look into trying to fit more RAM into the laptop,if you can

*Make sure you know you absolutely have your latest vid card drivers,from the card's manufacturer site.This can ensure your card is optimized for the latest games*

Turning off shaders 2.0 probably wont help your games,in fact some games actually require shaders 2.0,so i'd leave them on,at least for the time being.

Defrag the main drive also,this causes stuttering if the drive is fragmented

Let me know how you go on.
