FCAT Frame Time 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:
- R9-295x2 does roughly 95 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 spike 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 40 ms to 50 ms 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.
And here the FPS plot for today's tested card, recorded for 28 seconds in the timedemo.
