Alien Isolation Frame Experience Analysis

Above, the percentile chart of 55 seconds of gaming. Here we plot FPS and place it in relation to percentiles.

• 50% of the time measured frames is doing just over 150 FPS, which would be the average framerate.

The higher and flatter the line, the better.

On this 55 second run the graphics card manages to stick at roughly 10 ms!!! (lower is better). We see one, maybe two extremely tiny stutters in the chart. You can't see these on-screen though. That's downright nothing. Again, with this chart, lower = better as, the faster one frame is rendered, the lower latency will be. Huge spikes above 40 ms to 50 ms can be considered a problem like a stutter or indicate a low framerate. What you see right there is tremendously impressive actually.
