How Do We Benchmark Graphics At 4K Resolutions?
Benchmarking At 4K
Unfortunately, we can’t use the DisplayPort interface for our testing. The whole point of FCAT is recording video from the display output, which is then used by a combination of Perl scripts to analyze frame rates. As it stands, capturing video at 2560x1440 already maxes out the Datapath Ltd. card responsible for that task. By splitting the stream into two HDMI signals, however, creating a pair of 1920x2160 outputs, we keep the capture manageable.
The rest of what we do remains very similar to the FCAT-based analysis we adopted months ago. Even though only one panel’s output is memorialized in video, because the graphics subsystem is still rendering to two, the performance measured by our capture card still reflects the complete experience.
Today’s exploration only involves one GeForce GTX Titan, two GeForce GTX 770s, two GeForce GTX 780s, and two GeForce GTX Titans. This is by design.
AMD is now up to its Catalyst 13.10 beta driver, which incorporates the company’s frame pacing functionality that was so warmly received in Radeon HD 7990 Vs. GeForce GTX 690: The Crowd Picks A Winner. We also quantified the benefit of frame pacing in Dual-GPU Battle: Does Frame Pacing In Catalyst 13.8 Turn The Tide? The caveat was that AMD only supports this feature at resolutions up to 2560x1600. Eyefinity, which is needed by Asus’ tiled PQ321Q, isn’t yet enabled either. So, rather than publishing a bunch of graphs that remind everyone what a lot of dropped and runt frames look like, we’re simply omitting multi-GPU configurations in CrossFire for the time being. AMD is fully aware of the issues preventing a good experience at 3840x2160, and we’re now hoping to get our hands on its phase-two frame pacing driver before the end of the year. That’ll be the release expected to add support for higher resolutions, Eyefinity, DirectX 9, and OpenGL.
