I have another thread with screenshots of that. I did not have that issue with my 680's in SLI so its something with the kepler and maxwells and how they are using the SLI driver and the game. There are multiple people with 7xx's Titans and 9xx's in SLI, Triple and Quad all having the same issue and a separate thread open for that issue.

In order to actually raid, I have to drop to one GPU, but I am still getting 80 fps uncapped in instances. at 1440p, one GPU, settings to max with SweetFX and other AA running, that is pretty damn good performance from a 350 dollar card.
I noticed this too and I think it has more to do with the switch from 1080p to 1440p. I was running advanced lighting on high @ 1080p fine for months on my 680 SLI. I picked up an Asus Swift PG278Q 1440p monitor and still ran the 680 sli and noticed stuttering or frame pacing/dropping issues. I moved up to SLI 980s and the issue still exists on high advanced lighting. There is more than enough gpu power pushing for this not to be an issue, but the game is choking somehow. I'd say its either an effect that scales with resolution rather than having a set resolution itself (think full res DOF effects in other games) or its a drawcall/bandwidth issue. I never set my resolution back to 1080p to confirm this, but I highly doubt its related to the hardware itself.
