UPDATE:
As a workaround, enable dynamic shader generation in the video configuration. This fixes the problem but I'm currently testing to see whether there are any side effects on Nvidia cards. Are Nvidia drivers becoming like AMD/ATI drivers now? That option is supposed to be for AMD/ATI.
UPDATE 2:
Yeah, as I expected this workaround causes various graphical and text glitches in games. Depending on the game, these glitches range from minor glitches to pretty bad.
