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 22 FPS on average in this scene sequence
• R9-270X does roughly 34 FPS on average in this scene sequence
• R9-280X does roughly 47 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 longlasting. 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. And yes the R7-260X is at high latency, that indicates a low framerate, but remember this is measured at 2560x1440. That is not the resolution intended for a card like this. Absolutely no worries.
