Thank you, and no problem!
I'm looking over your computer specs, and your processor is on the weaker side. For optimal performance, try playing with as few things open as possible. Including extra browser tabs/windows. You can also try to monitor your RAM usage using the task manager. You may have programs running in the background that are reducing your performance(HP bloatware like HP Assistant/Advisor). Also, your graphics card shares memory with the rest of your rig. So really, your processor should be plenty good to run the game, it's just that your computer is possibly starving for free ram. So try to only use the built in notebook monitor, and as I said before, run as few programs as possible while playing. With the way your computer works, having extra tabs open will increase ram usage, and reduce performance. If you were running a YouTube video in another tab or something like that, you would notice a dramatic change in performance most likely (especially if you run it in HD).
