Gaming at 4K Resolution
Putting the teething issues aside, I loaded up Crysis 3 to put my GTX 780Ti through its paces. Setting the resolution to 4K (3840 x 2160) and all other options except Anti-Aliasing to “Very High”, I was greeted with the most breathtaking gaming visuals I have ever seen. Textures were crisp to the point of being photo-realistic and the game just looked amazing. At 25 Frames Per Second. Hmmm. It became quickly obvious that one of the fastest single-chip graphics cards in the world was simply not good enough to run games with this standard of visual fidelity, as it has to push 4 times as many pixels as 1080p.
