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.
We see a similar trend in our first gaming benchmark, BioShock Infinite. Running with two of Gigabyte's GeForce GTX 980s sees in-game performance increase by 75 per cent. Introducing a third GPU adds only 13 per cent on top.
If it's playable framerates and not 3DMark records that matter to you, it's worth pointing out that Radeon R9 295X2 is a very good bet: the dual-GPU card is now available for less than Ā£500 and averages over 60 frames per second in this title.
Digging deeper into the results, we can observe how smooth the gameplay experience really is by logging how many frames are rendered within 17ms (equating to around 60fps if considered for a full second) and recording how long it takes the GPUs to render the slowest one per cent of frames.
A higher percentage on the left graph coupled with low frame times on the right are an indication of smooth gameplay absent the unwanted choppy frames.
