When the performance of something significantly degrades over time.

The names comes from the Nvidia Kepler GPU architecture (GeForce GTX 600&700 series), which was infamous for suffering severe and steadily bigger performance losses in games after its release.

This was caused by poor optimisation in Nvidia’s drivers after the release of the Maxwell architecture (GeForce GTX 900 series), as without shader optimisation the raw performance of Kepler cards fell off a cliff.

West Midlands slang word for rockers, bikers, greasers etc. In the late 1980s it was used by the UK music press to refer to a specific scene centered around the bands Pop Will Eat Itself and Crazyhead. The term never found favour with readers of 'the inkies' (Sounds, Melody Maker and the still extant NME) and was soon dropped. Now often used in predominantly working-class areas of the midlands and the north to mean someone who listens to rock-derived music and/or dresses in a manner that suggests they affiliate themselves with rock music of some kind.
