Please excuse my ignorance here but I am not a gamer
Are the two games that you are having issues with played via Steam online, the reason that I ask is I noted the presence of AVG Safeguard in your Speccy results, AVG (even the toolbar) on it`s own is demanding on system resources but put it alongside another AV program such as MSE in this instance and it will drop your system performance and cause conflicts, use the AVG uninstaller tool to get rid of the AVG toolbar to ensure that nothing that can cause conflicts is left behind,
