Frame Experience Analysis - Metro Last Light

Metro 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 60 FPS.
• 5% of the frames is at 25 FPS or lower. 

For those that do not understand what you are looking at, the above is a gametime scene recorded for 30 seconds. On this 30 Second run both the graphics cards show spikes and visibly noticeable stutters. This happens with ALL cards tested at any resolution and any brand, so it is A4 game-engine or system related.With this chart, lower = better. Huge spikes above 40-50ms can be considered a problem like a stutter or indicate a low framerate.

Though NVIDIA seems to behave a notch better, the R7990 is being really impressive here though. Again the three stutters are game enigine related. We do not see any microstuttering, but do see three dropped frames.

Our plotted chart confirms that there are three dropped frames, but again... you will not notice these.
