4K Resolution Testing
We also ran a handful of tests on the GeForce GTX 780, GTX 780 Ti, and Radeon R9 290 and 290X 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.
Although the Radeon R9 290X outpaced the original GeForce GTX 780 in all of the games we tested at 4K, the new GeForce GTX 780 Ti's beefier GPU and ultra fast memory allow it to take the lead in half of the tests.
