FCAT Frame Experience Analysis Metro Last Light
Matro Last Light Frame Experience Analysis
Above, the percentile chart of the 30 seconds gaming @ 2560x1440. Here we plot FPS and place it in relation to percentiles.
- 50% of the time measured frames is doing 49 FPS.
- The last 5% of the frames is at 28 FPS or lower.
For those of you that do not understand what you are looking at, the above is a gametime scene recorded for 30 seconds. On this 30 second run the graphics cards all show massive spikes. and thus indicate stutters, we can confirm these as visible on screen. This happens with ALL cards tested at any resolution, so it is Metro game-engine related.
With this chart, lower = better. Huge spikes above 40-50ms can be considered a problem like a stutter or indicate a low framerate. During the recording I focuessed soley with my eyes on the monitor and noticed four to five visible stutters. This correlated perfectly with with the graph as five stutters are peaking well above 40ms. Again this is game engine / benchmark related.
