3DMark Time Spy
Rendered at a 2,560x1,440 QHD resolution and making use of DX12 technologies such as asynchronous compute, explicit multi-adapter and multi-threading, Time Spy is a forward-looking 3DMark benchmark that hints at GPU potential in various upcoming games.
Performance scaling is solid in these synthetic tests, and so too is stability - adding a second card did not have a detrimental effect on the Time Spy Stress Test.
