4K Resolution Testing
We also ran a handful of tests on the Radeon R9 290, R9 290X and GeForce GTX 780 using a tiled 4K display with a native resolution of 3840x2160. Unfortunately, for these tests, we could not record frame times using our FCAT tools. We’ve been fighting with the setup for weeks, trying to get captures working using the HDMI inputs on the screen, but have been unsuccessful in our attempts. We are still trying though, and are hoping to include FCAT results at 4K in the future. For now, we only have minimum and average frame rates to share.
For these tests, we cranked the quality down a notch in a quartet of games. In AvP, we lowered the anti-aliasing to 2X, from the 4X we use in our standard tests. In Hitman and Sleeping Dogs, we lowered the AA level to 2X as well, in addition to reducing in-game image quality options to their high-quality settings. We simply increased the resolution in Bioshock, however.
As you can see, save for Bioshock Infinite, where the GeForce GTX 780 finished just slightly ahead of the Radeon R9 290, the Radeons offered the best performance overall at 4K. In AvP, Hitman Absolution, and Sleeping Dogs, the Radeon R9 290 was about 10% faster than the GeForce GTX 780.
