Recent patch creating massive graphical artifacts

[Imaginary_Star]

As a preface, I had no big graphical issues with the game since beta, but one of the recent patches (not sure which one, since I had not played for over a week) introduced some major issues.

Upon entering maps I can immediately see some dark, shifting graphic artifacts, that change as I move/look around.
Some maps have random textures stretch across the portions of the sky, rendering the game nearly unplayable.

AMD Radeon 6550M is the video card.

Yep. Try updating drivers, and then post back results.

I've actually had this happen several times and it were pretty much always driver issues.

Seems like it was the issue, though auto driver update did not detect the new version, there was one.
Thank you.
