Laptops normally run on DualCore processors, that is why it might just be the bottleneck. Recording on laptops is very hard even if you have top-of-the-list laptop.
If you don't know what is your CPU, I recommend running CPU-Z and check from there the info.
Last two Toshibas laptops I had broke down, also broke FuSi's laptop... Laptops, aaargh!
