FCAT Frame Experience Analysis BioShock Infinite

BioShock Infinite Frame Experience Analysis

Above a percentile chart of the 30 seconds @ 2560x1440. Here we plot FPS and place it in relation to percentiles. This methodology could be used to determine average FPS as well.

Check the 50% marker:

• R7-260X does roughly 21 FPS on average in this scene sequence
• GTX 780 does roughly 63 FPS on average in this scene sequence
• R9-290X does roughly 58 FPS on average in this scene sequence

But now lets look at frame latency.

On this 30 Second run the graphics cards all manage a good result. Despite one or two very small spikes we cannot detect a glitch or stutter that is significant or long-lasting. 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 40ms to 50ms can be considered a problem like a stutter or indicate a low framerate. We see one spike, but honestly nothing to worry about as the overall plot is extremely smooth. 

Concluding on FCAT, the results show a very synchronous frame experience. It is as good as it is going to get.
