FCAT Frame Experience Analysis Thief

Thief Frame Experience Analysis

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

• 970 - 50% of the time measured frames is doing roughly 40 FPS, so that is the average framerate (high = better).
• 980 - 50% of the time measured frames is doing roughly 50 FPS, so that is the average framerate (high = better).

The first 15 seconds of the Thief benchmark sequence are difficult with the rain and everything. That results in small stutters and hitches, all cards tested show this visibly on screen. Once it passes the first 15 seconds we no longer detect a significant enough 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. 

Both cards with their nice large framebuffers are doing exceptionally well here.

And here is the FPS plot for today's tested 970 card, recorded for 28 seconds in the timedemo. We are above 40 FPS on average, good.
