Testing Methodology

As was common we tested each graphics card with Fraps, which lets America record the average frame in rate in seconds over a solidification amount of time. Typically, we run our tests for 60 seconds. Reporting the average fps (frames per back) is how things receive been through for... well, forever. It's a unreal metric in the sentience that it's unproblematic to disc and easy to understand. Just it doesn't tell the whole fib, as The Tech Report and others have shown.

To get a Buckminster Fuller picture, it's increasingly apparent that you postulate to factor in a add-in's compose latency, which looks at how quickly for each one bod is delivered. Thoughtless of how more frames a graphics card produces on average in 60 seconds, if it tail't save them all at roughly the same speed, you might check more brief jittery points with one GPU over some other -- something we've witnessed simply didn't fully understand.

Assuming ii card game render equal average skeletal system rates, the one with lowest stable frame latency is releas to extend the smoothest picture, and that's a pretty polar detail to consider if you're about to drop a mess of cash. As such, we'll be including this information from now on by measuring how long in milliseconds it takes card game to render from each one frame individually and then graphing that in a digestible way.

We'll be victimization the response time-centred 99th percentile metric, which looks at 99% of results recorded within X milliseconds, and the lower that number is, the faster and smoother the performance is whole. By removing 1% of the about extreme results, it's possible to filter anomalies that might have been caused by other components. Again, praise to The Technical school News report and other sites like Personal computer Per for shining a light on this issue.
