1080p - 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.
Do more with less is the Maxwell mantra. Forget die sizes, TDPs and cost for a moment, the GTX 980 is the fastest GPU in our line-up.
We can also calculate the percentage of total frames rendering in under 17ms, equating to around 60fps if considered for a full second. We'd ideally want all frames to be within this timeframe, intimating super-smooth gameplay, but higher remains better.
No GPU has any real difficulty in maintaining excellent frametimes.
Moving on, we can also determine just how poor the slowest one per cent of frames are. You want the slowest to be, well, not that slow, because your eyes perceive choppy frames far more readily than fast ones.
99 per cent of the GTX 980's frames are rendered within 16.9ms. It's only the two Radeons that semi-struggle with this test.
