Display driver crash if too many iterations

-

i've made computationally intensive filter many loops and

when push on limit screens go blank a

moment , see "display driver recovered" message

and pixelbender frozen. crash happen when

it takes around 3-4 seconds filter finish.

 

in pixelbender tolerance higher in photoshop

plugin crash occurs @ around 10% less iterations.

 

my pc running windows 7 x64 , has nvidia gf8800 gt 512 mb.

 

any suggestions why happens?

can post filter or more info on steps repro bug? how many loops have?
