I need to see some actual evidence that nvidia is making performance worse over time for Kepler.
Like driver #1 is faster than driver #2 is faster than driver #3, where #3 is the latest in the series, etc.
And I think we need a bigger sample size than four games, two of which just came out.
If you revert to 347.88 drivers you get better performance in the Witcher 3 than with the release day Witcher 3 drivers.
Why do you need evidence by the way? Are you planing on buying a 7xx series or do you own one? I own a 7xx series card and this is a problem for me, the evidence is in how the new games I play are playing like shit on my card, not only in overall FPS but in the hard drops I get while playing games too.
