A A measure of gaming performance that includes average Fps and frame drops.
The effective Fps (EFps) approximates gaming experience by measuring the speed and stability of frame times. Inconsistent frame times result in stuttering which ruins the gaming experience. EFps is calculated as the average of the following seven key statistics:

Min, Avg and Max

The minimum, average and maximum figures are calculated from the rolling one second Fps average. These statistics are shielded from the absolute minimums and maximums by taking a complete one second window rather than individual frame times.

0.1% and 1% Lows (Avg|Max)

To calculate the 0.1% low we first sort all the frame times in a sample from slowest to fastest. For a 60 second sample, the frames that are in the first 0.1% = 60s * 0.1% = 60s/1000 = 0.06s are used for the 0.1% low. We calculate the average and maximum Fps of those frames. These two figures are our Avg|Max 0.1% lows which can be used to measure stuttering and framedrops. A similar calculation is done for the 1% lows.
