Braid is a puzzle-platformer, drawn in a painterly style, where you can manipulate the flow of time in strange and unusual ways. From a house in the city, journey to a series of worlds and solve puzzles to rescue an abducted princess.
If you have been having problems on AMD cards running Braid, this driver is likely to fix the problem:

Over time this fix should make its way into the non-beta driver.
