Understanding Dynamic GPU Performance Mode
With the Release 280 drivers, NVIDIA GPU clock speeds will increase more quickly in
response to increased graphics demands. Conversely, with lower graphics use the GPU
clock speed slows down more quickly, conserving as much power as possible.
In the Release 280 drivers, some users reported a noticeable fluctuation in clock speeds
while engaging in various tasks on the PC. With the Release 285 and later drivers,
adjustments have been made to reduce the sensitivity to levels similar to the R275 driver.
