maddogfargo is also correct, ensure of your laptop has good air flow and ventilation particularly the bottom air exhaust.. if you can check dust or any that block the air passage and exhaust to cool down your pc.. your system will lag if its overheating.. also always wall plug your system whenever your playing games with intensive graphics - just observe if there's difference between battery power and plug..
In addition, monitor temperature of your cpu (CoreTemp will do) as well as gpu (GPU-z sensor will do)..
