I forgot to mention that because I have tried a no of solutions and I don’t even remember how many, actually I have already installed the direct x update as well and I had made sure that I reboot the machine after installing it but then it is making no such difference where I can say that the performance has been improved and now I will also like to add that after updating the graphics driver I am now having anti-aliasing problem with java as well because of which the text is also getting blurry and it is really appearing to be weird.
