Battlefield 4 VGA graphics performance benchmark review - FCAT Frame Experience Analysis Multi-GPU

FCAT Frame Experience Analysis Multi-GPU

But let's have a look at multi-GPU behaviour. Above a percentile chart of the 30 seconds @ 2560x1440. Here we plot FPS and place it in relation to percentiles. This methodology could be used to determine average FPS as well.

Check the 50% marker:

• Radeon R7-260X does roughly 21 FPS on average in this scene sequence
• Radeon HD 7990 does roughly 85 FPS on average in this scene sequence
• GeForce GTX 690 does roughly 70 FPS on average in this scene sequence

And again lets look at frame latency.

On this 30 second run all graphics cards manages to remain at a very constant rendering flow with fairly low latency for the two fastest cards. The Radeon HD 7990 is dropping frames a bit here and there though. NVIDIA actually does show the same with the 690, it's just not that apparant. Overall this is pretty good though, especially for the R7990 we can see that frame-pacing really works well.

For those that do not understand what you are looking at, the above is a scene rendered, the first 30 seconds of our benchmark. With this chart, lower = better. Huge spikes above 40-50ms can be considered a problem like a stutter or indicate a low framerate. For all three cards this is a really nice result and overall experience.
