    Display Driver Stopped Responding and Has Recovered -- (Vista TDR ?)

      Vista GPU automated recovery

      Hi Guys,

      While running a Brook program on Vista 32, I'm entering a recurring GPU reset crash (whenever the GPU load starts being heavy):

      "Display Driver Stopped Responding and Has Recovered"

      The program per se works fine, as long as the GPU computation time doesn't exceed a weird hidden limit... then the crash occurs.

      I suspected some form of a time-out watchdog and after some googling, I had a hint that this may come from a Vista TDR feature, which automatically tries to recover the GPU whenever nothing happens on the screen for some time.

      Is there any fix or tweak that may prevent Vista to perform this automated "recovery" whenever the GPU is still busy computing???
