AMD & NVIDIA 4K Gaming with the ASUS PQ321Q Testing:

Testing how well the XFX HD 7970 and GTX 770 perform in both single and multi GPU configurations will consist of runniing each combination through a series of games, most of which are in the OverclockersClub.com suite of games and synthetic benchmarks. The one notable removal from the suite is Metro Last Light as both the AMD and NVIDIA cards had issues running this game through the Dual HDMI interface at 3840x2160. In Lieu of Metro Last Light I will add Splinter Cell Blacklist in its place.

The system specifications will remain the same throughout the testing. No adjustments will be made to the respective control panels during the testing to approximate the performance the end user can expect with a stock driver installation. The NVIDIA comparison cards will be using the 327.19 drivers while AMD-based cards will be using the Catalyst 13.19 beta. The results generated in my testing reached by utilizing the latest FCAT tools to illustrate the true picture of the gaming experience. To do so will require a second PC setup to capture the data stream generated by the compared video cards.

FCAT Capture Setup:



 

Setting up the FCAT tools to be able to measure the output signal to the display creates some challenges in measuring the raw data just due to the screen size and is more along the lines of measuring the results when running a 5760 x 1080 resolution. You can take a look back at our introduction to FCAT or Frame Capture Analysis Tool for a more in depth look at the technology and hardware required to pull these results. While FRAPS is a valid measurement for what it does, it does not give an accurate picture of what is actually hitting the screen. For that reason we choose to stay with FCAT as our method for capturing FPS and illustrating anomalies in performance from one manufacturer to the other. To capture the data stream going to the PQ321Q the setup is a bit different than capturing the data at lower resolutions. Since we have a two monitor setup basically with the UHD panel, we can hook up the hardware-based capture solution as indicated below to keep the data stream at a manageable level.

 

Gaming Tests:

  • Splinter Cell Blacklist
  • Crysis 3
