FCAT Frametime Performance Single GPU

 

Frametime Performance GeForce GTX 980 & Radeon R9 290X 

With a benchmark technology called FCAT on the following two pages, we will look into Frame Experience Analysis. Basically with the charts shown we are trying to show you graphics anomalies like stutters and glitches in a plotted chart. Lately there has been a new measurement introduced, latency measurements. Basically it is the opposite of FPS.

  • FPS mostly measures performance, the number of frames rendered per passing second.
  • Frametime AKA Frame Experience recordings mostly measures and exposes anomalies - here we look at how long it takes to render one frame. Measure that chronologically and you can see anomalies like peaks and dips in a plotted chart, indicating something could be off. 
Frame time
in milliseconds
FPS
8.3 120
15 66
20 50
25 40
30 33
50 20
70 14

We have a detailed article (read here) on the new FCAT methodology used, and it also explains why we do not use FRAPS anymore. Frametime - Basically the time it takes to render one frame can be monitored and tagged with a number, this is latency. One frame can take say 17 ms. Higher latency can indicate a slow framerate, and weird latency spikes indicate a stutter, jitter, twitches; basically anomalies that are visible on your monitor.

What Do These Measurements Show?

Basically, what these measurements show are anomalies like small glitches and stutters that you can sometimes (and please do read that well, sometimes) see on screen. Below I'd like to run through a couple of titles with you. Bear in mind that Average FPS matters more than frametime measurements. It's just an additional page or two of information that from now on we'll be serving you.

Frame Pacing Enhancements Single GPU


 

980


Above a frame-time recording of the internal benchmark @ 2560x1440 performed with a single GeForce GTX 980. So the light grey line is the benchmark. The benchmark is time based, meaning the quicker it finishes, the faster the card. The GeForce GTX 980 is showing exceptional smooth performance without any stutters. The one spike is due to the internal benchmark changing scene and loading shaders into graphics memory, you will see that with any graphics card. 

 

290x

Let's have a look at the AMD Radeon R9 290X. As you can see if you compare with the GeForce GTX 980, the resul is close to similar. Perfect rendering, you are looking at excellent frame-rates without micro-stuttering or serious enough anomalies. On the next page we'll address multi-GPU solutions in terms of Crossfire and SLI.
