Tomb Raider Frame Experience Analysis


5618_per

Above, a percentile chart of the 30 seconds @ 2560x1440. In this particular chart we plot FPS and place it in relation to percentiles.

  • 50% of the time measured frames is doing 33 FPS. 
  • To the right you'll notice that the last 5% of the frames is at roughly 28 FPS or lower. This is another and valid way of looking at performance.

For comparative reasons and a little extra scaling in the charts we include a GeForce GTX 760.

5619_plot

Above, the card at 2560x1440. You'll notice that here frametime scaling (chart wise) still needs to be altered, the charts are incredibly blown up, but on this 30 second run the graphics card manages to remain roughly below 17ms.

There are no recordable stutters or weird things measured with the graphics card whatsoever, what you see here is rendering perfection. 

The plot is averaging roughly 30ms to roughly 35 ms per rendered frame. With this chart, lower = better. Huge spikes above 40-50ms can be considered a problem or indicate a low framerate. Spikes below 5ms indicate a frame being dropped.
