Performance - 2-way SLI GPU - Tomb Raider

GeForce GTX 980 2-way SLI DX11: Tomb Raider

Lara Croft is back and has the distinction of being one of the true breakout stars of gaming, an icon every bit as important as Mario or Sonic. But in many ways, she has always taken second place to the titular Tombs of the games she inhabits, with attempts to flesh out her character some of the weakest moments in a venerable series of games.

This particular test has the following enabled:

• DX11
• Ultra Quality mode
• FX AA enabled
• 16x AF enabled
• Hair Quality Normal (TressFX disabled)
• Tessellation On
• SSAO Ultra

We are testing at 2560x1440 (WHQD). With an exception here and there, this is roughly what you will see in terms of performance difference, from Gen 1.1 to 3.0 that is close to 8 FPS on average, thus 4% over the entire scope of bandwith --  not at all interesting.

Frametime Recording

• Grey line - GTX 980 @ x16 Gen 1.1
• Dark green line - GTX 980 @ x16 Gen 2.0
• Light green line - GTX 980 @ x16 Gen 3.0

We once again spread out the 57 second benchmark recording and then overlay latency results from the difference generation PCIE slots (lower latency - better) we can see a hint better as to what you are seeing on screen. The latency differences in-between the PCIE Slot configurations are close to nothing. The latency difference is so low here as in SLI we render roughly 200 FPS on average, that's the 4 to 5 ms marker per frame rendered here.
