BioShock Infinite Frame Experience Analysis

Above, the percentile chart of the 28 seconds gaming @ 2560x1440. Here we plot FPS and place it in relation to percentiles.

• GTX 970 - 50% of the time measured frames is doing roughly 65 FPS, so that is the average framerate (high = better).
• GTX 980 - 50% of the time measured frames is doing roughly 75 FPS, so that is the average framerate (high = better).

We cannot detect a significant glitch or stutter in frametime scaling (chart wise) that is extremely significant or long-lasting. For those that do not understand what you are looking at, the above is a gametime scene recorded for 28 seconds. With this chart, lower = better. Huge spikes above 40ms to 50 ms can be considered a problem like a stutter or indicate a low framerate.

All cards show minor glitches so it is game engine rendering related. Again these are impressive results.

And here is the FPS plot for today's tested 970 card, recorded for 28 seconds in the timedemo. We are way above 60 FPS on average, good.
