4K - BioShock Infinite
BioShock is fantastically playable and looks great on the PC. We benchmark a 60-second section near the start with all available eye-candy turned on.
The wow-factor of 4K gaming is, we feel, a key reason to upgrade your PC hardware. But are the new GPUs enough of an improvement to drive over eight-million pixels? BioShock Infinite is certainly playable, and it does look fantastic, but we're some way off the desired 60 frames per second.
Keeping the demands of 4K gaming in mind, we've adjusted the frame consistency to measure the percentage rendered within 33ms, equating to around 30fps if considered for a full second. A card would ideally need to score in excess of 90 per cent to be considered playable, so this particular benchmark does a good job of separating the wheat from the chaff: a fair few previous-gen cards can't cope with this sort of demand.
Still rocking a GTX 680, or, God forbid, something older? Now might be the time to consider an upgrade.
