Hello again and my apologies for posting due to my problem.
So recently, I have done a fresh install of Windows 7. I have also gotten my drivers updated along with the necessary programs installed too like anti-virus, etc. But why I have noticed is that whenever I were to exit the program using the red cross, it will have some 'lag' issues but it doesn't happen on Alt+Tab or minimizing. Any help would be appreciated. Sorry for my poor explaination. And thanks for viewing and replying.
