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 SLI - 50% of the time measured frames is doing roughly 75 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.
But again, you can see a lot of framedrops. This issue continued persistently through all FCAT results. We are still investigating what is going on there. These are not stutters, frame-drops like these can not be seen with your eyes.
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.
