I was wondering if people could post their FPS while watching 4K video on YouTube or other 4K sites with the specs of their GPU as well. To start: Video: Surf NYC (4K resolution) http://www.youtube.com/watch?v=9dgSa4wmMzk CPU: Intel Core i7-920 (D0) @ 2.66Ghz (stock) RAM: 8 gb DDR3 @ 1066 MHz GPU: Visiontek Radeon HD 5870 Core clock: 850MHz Memory clock: 1200 MHz Using Fraps, I got these results: Min. Max. Avg. (frames per second) 14 28 20.992 I'm curious to see what other people get as results. I believe an alternative to using Fraps is right clicking in the video window and click "show video info". (YouTube). However this does not show an average frame rate, and only updates once a second.
