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 54 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 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 recently moved from 60 seconds frametime recordings towards 30 seconds. The 60 seconds black bar is a GTX 980. Overall you'll see the same behaviour for all cards with minusculeframe drops.
