A friend of mine has just upgraded from Windows xp to windows 7 ultimate, he is happy with the performance of his pc but he keeps getting graphical glitches on the steam overlay and in Cliffs of Dover il2. On the steam overlay they are red in the game cliffs of dover they are blue.
Here is a picture of the glitch in steam below, all the drivers are installed, the only thing I should mention is the PC wouldn't shut down after updates and needed to be forced to shut down the same day windows was installed.
I took a look at his pc last night uninstalled drivers and reinstalled them. Visited the microsoft website and downloaded direct X runtime and run it.
Is this a direct x problem still?, when file was run it read your direct x is up to date.
