BioShock Infinite Frame Experience Analysis

5968_per

Above, the percentile chart of the 30 seconds gaming @ 2560x1440. Here we plot FPS and place it in relation to percentiles.

  • 50% of the time measured frames is doing 80 FPS.
  • 5% of the frames is at roughly 50 FPS or lower.

On this 30 Second run the graphics card manages to remain roughly below ~20ms, we see one visial glitch or stutter, but its hardly worth mentioning really. For those that do not understand what you are looking at, the above is a gametime scene recorded for 30 seconds. With this chart, lower = better. Huge spikes above 40-50ms can be considered a problem like a stutter or indicate a low framerate. Overall we see measure tiny hint of microstuttering for AMD, but it's so incredibly low in latency that it is not possible for the human eye to see it really. That actually is very impressive.

One problem seems persistant though, dropped frames, this round we count nine of them.
