In an ideal world what we want to see is a nice slim 'fuzzy' line stretching from one end on the chart to the other. What we do not want to see are 'spikes'. This spikes are delays in frame time rendering and are where stuttering will occur if they go above a given threshold.

Random, thin spikes are not too much of an issue however should there be a block of spikes in close proximity to one another, especially if these spike jump quite high will likely be noticeable and interpreted as 'stutter'.

Using Frame Time Analysis as a means of measuring GPU performance is clearly a valuable tool. So much so that some would say it should replace the frames per second method of measuring performance. We would tend to agree because as previously stated, it is little point in having a GPU that can produce stupidly high framerates if the end product results in choppy gameplay. For gamers, frame time latency is clearly the better measurement as it is what 'gaming experience can be measured upon'.

Sure, a frametime graph can show you which is the faster card simply by it's length and thus the number of frames rendered over a given period but to get an accurate figure you would also have to calculate this yourself to gain an accurate, by the second average FPS figure. It's no good saying an entry level card has excellent frame time latency and then comparing it to a much faster (FPS) card which has a slower latency. IF both cards are below your own perceived level then you would obviously go with the faster card.
