Benchmarks: DOOM, The Division, Ashes of the Singularity
Unfortunately, the scaling seen in DOOM was rather sad - we saw a meager 21% increase in performance when adding a second Palit GTX 1080 GameRock PE graphics card.
Up until recently, SLI didn’t work at all in Tom Clancy’s The Division, so seeing the performance scale by up to 65% isn’t too bad, considering. This also meant that the game went from a slightly choppy 43fps to a silky smooth 71fps at 4K.
Sadly, even under DX12 with multi-GPU technology enabled, the scaling in Ashes of the Singularity is very poor.
