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. As you can see at 50% of the frames is rendered at roughly 45 FPS for a single tested card and it goes up to ~65 FPS when going for a 2-way SLI.
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 40 ms 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.
