Crysis 3
Crysis 3 is a beautiful-looking game that continues to tax high-end systems. We've benchmarked a 60-second section near the start of the game, with lashing rain, numerous reflections and full DX11 pomp on show. 4xMSAA is enabled at 1080p and disabled at 4K.
A single Sapphire Radeon R9 295X2 is swamped by the load imposed by Crysis 3 at very-high quality settings and a 4K resolution. Such swamping limits the ability of the card to perform to its potential. Adding a second card takes care of this bottleneck enough for performance to increase by almost 2x, or near-perfect scaling.
Want to play Crysis 3 in full 4K pomp? A grand's worth of AMD hardware ought to do it.
The vast majority of frames are rendered within 17ms on the Sapphire duo - impressive.
Lots of sub-17ms frames usually means, as in this case, that the worst one per cent won't be so bad. The 99th percentile is crossed at a reasonable 29.9ms.
