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.
This is promising. Two R9 295X2s are faster than three overclocked GTX 980s. 4K performance is lush and smooth.
The two 'X2s produce a large number of frames within 17ms, as expected, and the slowest one per cent of frames occurs at the 22.7ms mark. Factoring these two observations together enables us to say, rather obviously, that AMD wins out here... at a fraction of the WaterForce price.
