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.
Here's where it should get interesting. A 1080p resolution is a doddle for high-end cards. 4K quadruples the number of pixels and places a commensurately larger load on the GPUs. GTX 980's 4GB framebuffer and improved memory performance keep it ahead of the GTX 780 Ti and R9 290X.
We've changed the standard from 17ms to 33ms, to better reflect the kind of performance we expect to see at 4K. In BioShock the quality levels remain exactly the same as at 1080p.
What's telling here is that GTX 770, GTX 680 and the R9 290 don't cut the mustard; these settings are a reach too far for them.
The game does slow down in places, evidenced by the 99th per cent frame taking 42.1ms (circa-24fps over a full second) to be spat out of the card. Note the three slowest cards; their worst frames are poor.
