Today I was playing CS online game on my p48 and few people came and asked for “How to run CS 1.6 in my Windows 8?”. It was just loaded on Software mode and bad graphics. And I researched on my friend’s Windows. Previously we couldn’t play Angry birds on the same PC and did some research. And found that the internal default graphics driver needs to be installed. Then I downloaded the Update for Windows and download the remaining packages on windows 8. And found the remaining after the first update of Windows 8. And clearly see the Intel graphics driver. Then I ran the Angry birds and it went good.
After the successful test for Angry birds, I tried opening the game in OpenGL mode and whoooo it ran successfully and very smooth. I can’t feel the difference in any part between the previously played game and now. But the fps has decreased but soon the bug might be fixed for Windows 8.
So, I suggest you to download first:

Update for Windows (KBXXXXX)
And after few minutes, try checking for windows update or restart Windows
It automatically checks for update and install the Intel graphics driver.

Happy fragging.
